Stopped Working Rated 3 out of 5 stars
My system is Ubuntu 11.04, 32bit, the addon worked well when I installed it. But after I reopen my Firefox 4, it didn't work at all.
If I want it function normalily, I have to restart the addon.
Problem is that I have to restart every time I open my browser.
I really love the function, but the bug bothers me a lot.
Could you make sure you are running v4 or v5? That should fix the problem from v3.
