The features of this extension are:


Unified Back-/Forward Button 0.6 [released 2007-08-25]

This release works for Firefox 2.0 (mainly tested with the Winstripe theme).

Note: Parts of this extension have been integrated into Firefox 3.0, so there won't be another update.


The maximum length of the unified menu can be changed by creating a new Integer pref called browser.sessionhistory.unified_length in about:config and setting it to a value different than 11 (the default).


The button could be styled further through userChrome.css. E.g. to make it easier to hit with the mouse:

/* Fitts' Back Button - bigger target on the icon-only toolbar */
toolbar[mode="icons"] #back-button > [anonid="button"] {
   -moz-box-orient: horizontal !important;
toolbar[mode="icons"] #back-button > [anonid="button"] > label {
   display: -moz-box !important;
   margin: 0px 2px 1px 2px !important;
   -moz-margin-start: 5px !important;

And if you prefer the history to be ordered in reverse (earlier visited entries at the top):

/* Order the drop-down menu in the same way as the Forward button's menu */
#back-button[unified] > menupopup scrollbox > box {
   -moz-box-direction: reverse !important;


Back and Forward are as usual [Alt]+[Left] and [Alt]+[Right]. To access the drop-down menu, you can use the following keyconfig macro ([Esc] closes the menu):

document.getElementById("back-button").open = true;


Current: version 0.6
After the update, you might have to move the two buttons provided by Firefox to where the combined button used to be. Also any further customization through userChrome.css will have to be adapted.
The original Back and Forward buttons are merged now (a separate button is no longer provided).
The button parts can be individually added/removed from the toolbars.
