== Firefox 2.0 config tweaks ==

All of these tweaks are implemented in [b]about:config[/b] and are documented at the [[http://kb.mozillazine.org/Firefox_:_FAQs_:_About:config_Entries|Mozilla wiki]]. Any questions, make a thread in the forums, or add comments in here - just use the sig button (second from right) to sign any comments. :-)



=== Revert close button behaviour ===

Miss the old school "One close button to rule them all" interface, you luddite ;-)? Well, you can bring back the glory days of Fx 1.5.

Set [[http://kb.mozillazine.org/Browser.tabs.closeButtons|browser.tabs.closeButtons]] to **2**.
Changing it to **0** will only have a close button on the active tab - handy if you keep closing tabs by mistake when trying to select them. 

=== Reduce memory usage ===

Feature, bug, whatever, it was annoying, no?

Set [[http://kb.mozillazine.org/browser.cache.memory.capacity|browser.cache.memory.capacity]] to one of the following [[http://www.computerworld.com/softwaretopics/software/apps/story/0,10801,111065,00.html|recommended values]], dependent on RAM:

^ RAM ^ Value ^
| {{{<=}}}512MB | 5000|
| 512MB - 1GB | 15000 |
| > 1GB | You're having problems?|


=== Turn off prefetch ===

I never liked this, and being stuck behind a proxy that dies if too many concurrent HTTP requests go out, it's dangerous.

Set [[http://kb.mozillazine.org/Network.prefetch-next|network.prefetch-next]] to **false**.


=== Remove "go" button ===

Ugly and useless.

Set [[http://kb.mozillazine.org/Browser.urlbar.hideGoButton|browser.urlbar.hideGoButton]] to **true**.


=== Disable "Install Missing Plugin" ribbon ===

If you're unable or unwilling to install Macromedia's latest bloatware, you can nix the annoying ribbon that appears with every Flash advertisement.

Set [[http://kb.mozillazine.org/Plugin.default_plugin_disabled
|plugin.default_plugin_disabled]] to **false**. 
//(Note, you may need to restart Firefox for this to take effect.)//


=== Disable toolbar tooltips ===

If you're like me, you don't need a tooltip to find your stop button.

Set {{{browser.chrome.toolbar_tips}}} to **false**.

=== Disable large image resizing ===

I don't want large pictures made smaller. There's probably a reason why it's large.

{{{browser.enable_automatic_image_resizing}}} = **false**



=== Session preservation ===
To have whatever you had opened when you closed Firefox open again when you start Firefox, set the following:
* {{{browser.startup.page}}} = **3**
* {{{browser.sessionstore.enabled}}} = **true**


=== Spellcheck textfields ===

To use the spellchecker in textfields as well as textareas, set the following:
[[http://kb.mozillazine.org/Layout.spellcheckDefault|layout.spellcheckDefault]] = 2
