Thanks for providing the option to move buttons right before the tabs. But is there a way to show the actual hamburger menu symbol with the three horizontal lines instead of the big blue Thunderbird button?
EDIT: Amazing, thanks for the quick update! Really appreciated!
This review is for a previous version of the add-on (1.3).
This Add-on adds no button. In customize mode (right click on toolbar and select Customize) you should now see before the first tab a rectangle. Here you can move the AppButton ( ≡ ), or every other button, to this place. After ending the customize mode the AppButton changes to the style on the screenshots.
I hope this helps to understand my extension a little better.
Works great! Helps for TB17 to add the new AppMenu in front of the tabs-bar permanently. (see also bug "Appmenu" should permanently appear on "tabs-toolbar" https://bugzilla.mozilla.org/show_bug.cgi?id=795602)
