Upside down

We transfer the panels and tabs (tab) of Firefox down the window.

First thing

Find file browser.jar

In Ubuntu, it is usually located in / usr / lib / firefox-xxx / chrome /



From the archive we need browser.xul (content / browser /)

')

In it we change the location of the elements: arrange the menu and navigation below the window with the contents, the menu will also be done below the navigation:



...

<toolbox ...>

...

<toolbar id="nav-bar" ... >...

<toolbar type="menubar" ... >...

...



...





Update browser.xul in the archive.

Second act

Change the location of bookmarks (tab)

To do this, either in userChrome.css (located in the profile folder) or in browser.css (in the same archive browser.jar) add the style:



#content > tabbox { -moz-box-direction: reverse; }





Is done. We start.



PS Thanks to XUL, CSS, JS, the FireFox interface (Thunderbird, Sunbird ...) can be changed beyond recognition (for example, move the menu to the status bar).
