As we know from questions in this forum, many Mac users cannot find the menu bar in Adblock Plus preferences - it is located at the top of the screen rather than being inside the window. I checked this out a while ago, and there is no way to keep the menu bar inside the window on Mac. So the idea was to change the menubar into a toolbar (I though this was done in Firefox 3 for "Organize Bookmarks" but apparently it wasn't - "Import and Backup" is still inside a menu bar, it is only styled differently). I tried doing it on Windows and here is what I got:
This isn't too pretty of course, but more importantly there are some accessibility issues - access keys don't work, moving to the next menu is neither possible with the mouse (at least without clicking it) nor with the keyboard. So for the foreseeable future Mac OS X is going to be the only platform where this menu will be displayed as a toolbar.
There is a slight issue testing this because I don't have a working Mac emulator at the moment. Any volunteers willing to test an experimental build on Mac?
