Rated 5 out of 5 stars

I've been using Copy Plain Text version 0.3.5 with the latest Firefox 3.6.10 (currently 3.6.13) for a while now, and haven't noticed any problems.

I couldn't remember where I got it so searched in Google & found a few links; this one works:
http://rapidshare.com/files/412743995/copyplaintext-0.3.5.xpi

I compared ("diff") the contents of each file contained in the .xpi from that link with those in the .xpi I had installed and they were all identical, so it should be safe. It's a useful little extension.
