HOWTO: ENABLE:
Alternative CTRL+TAB Action - v50->
Introduced in the version is the option to change the default CTRL+ALT action from cycling through open tabs to cycling through the most recently used open tabs. So if you have forty tabs open and you have gone from tab #11 to tab #33 the alternative action will take you between the two without scrolling through all the tabs in between.
- Linux: - Edit > Preferences > General > Tabs (section) > Enable "Ctrl+Tab cycles through tabs in recently used order".
- Windows: - Tools > Options > General > Tabs (section) > Enable "Ctrl+Tab cycles through tabs in recently used order".
Autoscrolling (or Middle Button Scrolling)
Under Options/Preferences >> Advanced >> General tab >> Browsing section, tick the checkbox 'Use autoscrolling'.
Safe Mode

Cache Folder Path/Location: (Windows)
In the location bar, type about:config and hit enter
Right-click in the white-space, and choose New->String, then copy and past in
browser.cache.disk.parent_directory
Click ok.
In the next box, enter the full patch to the directory you want to store your cache in, i.e. C:\Firefox Temp\
Close Firefox.
Delete your old cache directories in C:Documents and Settings\%username%\Application Data\Mozilla\Firefox\Profiles\something.username
Restart Firefox. It will create the directory specified above, if it doesn't already exist.
This same technique can be used to move your cache to a larger or faster disk.

HOWTO: FIX:
Keyboard Shortcuts Not Working
If the 'Home' and 'End' keys are not working press 'F7' and they should be activated.
Mobile Sites Opening On Desktop Browser
- Open 'about:config'
- Config name: general.useragent.override
- Right click on the entry and select 'Reset'.
Error Message On Start Up: "Well, this is embarassing...." not with my newest window & tab settings.
Answer: Completely disable session store
Firefox 3 and below: To completely disable all session saving behaviour, including the recording of session information, set browser.sessionstore.enabled to false in about:config.
Firefox 3.5 and above: Starting in Firefox 3.5 the preference browser.sessionstore.enabled is no longer used. [5] Instead, you can set the preferences browser.sessionstore.max_tabs_undo and browser.sessionstore.max_windows_undo to 0.
Error: 'inconsistency ld.so' crash caused by Google Talk Plugin
If you experience bad crashing with Mozilla Firefox 4, it could be a dodgy Google Talk plugin. Start Firefox from a terminal session command line and go to Google Maps. Or, to make it crash, just go to Tools > Add-ons. The browser will crash and show this error in the terminal...
Inconsistency detected by ld.so: dl-open.c: 583: _dl_open: Assertion `_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT' failed!
To fix it, rename the /opt/google/ directory to something else, reboot and try browsing again.
mv /opt/google /opt/google.old
Now try looking in the about:plugins page in Firefox.

Close Button Enabled On Last Tab: How To (v3.5 >)
When there is only have one tab left open it does not have a close button, because if you chose to close it Firefox itself would shut (unless you have implemented the 'Prevent Firefox From Closing When Shutting The Last Tab' 'about:config' tweak). It is still possible to close it pressing Ctrl + W, or selecting Close Tab in the File menu. While it is possible to tweak the coding of Firefox to archive this an easier method is to install an extension that provides the functionality.
