Titlebar Tabs Cleaner 0.4.1 Requires Restart
by Realraven (Axel Grude)
A toolbar button to remove the tabs from the Windows titlebar back to their original place. Provides an easy way to undo the changes introduced by Thunderbird 17 or switch between the two modes effortlessly.
About this Add-on
- right-click the Toolbar and select customize
- find the button "Titlebar Cleaner"
- drag it to your toolbar (I recommend the left hand edge)
The same can be achieved much more laboriously, by editing the configuration database directly, so if you only want to change it once and then "rip the knob off" you can do this by setting mail.tabs.drawInTitlebar to false.
