Comment 28 for bug 124581

The problem has been intermittent, and I haven't been able to find a trigger for it, so it is difficult for me to test properly.

However, it hasn't happened to me for the last week or so; I do have hardy-proposed enabled and am therefore now updated to 3.0 rc1. I would cautiously say that, for me, the problem appears to be solved. I shall continue to monitor and will test (with and without Compiz) if symptoms return.

For what it's worth the extensions I'm using are Adblock Plus 0.7.5.4, Download Statusbar 0.9.6.1, Ubuntu Firefox Modifications 0.5 and User Agent Switcher 0.6.11. Adobe Reader 8.0 Plugin is present because the Royal Mail postage label printer refuses to work with Evince... Other Plugins are present of course.
