Comment 9 for bug 396252

I also just started getting this. I can't see any patterns with websites, and it occurs whether or not my plugins (ABP, Noscript, firegpg, flashgot, torbutton) are enabled or disabled. A new user account also had the same problem.

This is on karmic, 2.6.2.6.31-14-generic, and firefox 3.5.4.

Hmmmmm, just then, pasting the output of uname -r into here (select, then middle-click in the text box) pasted the info twice... and pasting into another application in the same way sometimes pastes twice. I don't think this is a bug in firefox.
