Comment 71 for bug 65609

Hello,

I had Firefox 3 installed, and I preferred to install Firefox-2, the 2.0.0.14 version, in order to use some plugins that are not yet available with the 3 bêta 5 version of Firefox. So I did have a .mozilla directory in my home at this point.

I also found the same bug, and then found the thread here by searching on the web with the error message. I didn't get result by putting firefox profile away, but instant result came after putting the whole ~/.mozilla directory away. After restarting Firefox I could also add one more extension with no further problem.
