After downloading Firefox ver: 4.0b9, this alert keeps poping up. Never had it on 4.0b6. This happens two to three times as I back space to another page. A real pain. Going back to 4.0b6.

The problem is that you have the "colorfull tabs" extension installed. That is what generates this error. Try disabling it

I guess Tab Utilities add-on also causes this problem, only with a different Stack Trace value. I'm getting this message:

Stack Trace: 0:([object XULElement],[object XULElement],5512)

A work around is goto about:config

toggle the following line so that it is set to false.

browser.tabs.animate

I got the TabGroups manager 2011.22.01 extension, and sometimes when I close the last tab from a group the same error pops.
