Nice add-on for multi OS users Rated 5 out of 5 stars
While Firefox button is initially located on the left-top of the window when you use Firefox with Windows, the default position of the button in Ubuntu is right-top. That may be a trifle difference but always annoys me. This is what I wanted.
A small problem I met was:
When I installed this add-on and restarted Firefox, the bookmark tool bar didn't show up and I had to restart it in the safe mode to got something fixed. Ok, now I could put Firefox button from the customize window. But again, something went wrong. Starting FF in the normal mode and I found the customize window was disabled for some reason I couldn't figure out. Then, I got FF to restart in the safe mode and the matter to be fixed. Good. Every thing is all right.
Anyway, even though this add-on is not completely perfect, it really worked as I wanted and I'm happy now. Thank you.
