Why doesn't the bookmarking button doesn't work on Ubuntu?
When I use firefox on Ubuntu, the bookmarking button doesn't work unless I restart the browser. Why do I only get this problem on Ubuntu?
The shortcut key doesn't work either. The bookmarking feature on Ubuntu is broken.
Are you referring to this button? see screenshot Can you try downloading a separate version of Firefox to a folder? Run it from there and test the bookmark button.
