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.

This review is for a previous version of the add-on (4.1-signed.1-signed). 

Could you make sure you are running v4 or v5? That should fix the problem from v3.
