This seems to happen most frequently for Google apps (e.g. gmail) but I have seen it for other pages. I have seen this when all extensions are turned off.

Any ideas on how to fix this?

Do you have any extensions that deal with tabs ?

[object Window] would suggest there there is something wrong with JavaScript.

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 or userChrome.css 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

You can try to reinstall Firefox and drag the current Firefox installation to the Trash.

You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
