I would like Firefox to do something that seems to be "natural" in other browsers (it's one of the few things I like about other browsers): alphabetize the hidden extensions in the Tools menu (overflow menu) .
That, at least a simple task.
Now, if you wanted more points in your favor, that the overflow menu has a behavior similar to the Bookmarks menu, have the ability to sort items alphabetically on user request (selecting the corresponding option from the context menu).
Thank you very much. One more user since the first versions of Firefox, do not disappoint me, you are still on time.
