gmail in tab displays [object window]
I have a tab with gmail (mail.google.com). When I go to another tab and then come back it occationalls displays "[object window]". This only happens occasionally and is fixed when I refresh the tab. Any ideas on what might be causing this problem? Thanks.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

Thank you very much. It appears that it was the hardware acceleration which I found quite surprising. I turned that off and have not seen the problem since. Thanks.
