Status: RESOLVED INVALID

(Firefox :: Tabbed Browser, defect)

Description

[Michael van Rooyen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.0.3) Gecko/20060426 Firefox/1.5.0.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.0.3) Gecko/20060426 Firefox/1.5.0.3

Sometimes Firefox seems to lose track of how wide the main browser window is, and the viewpanes and the tab bar become too wide.  The little X that you would normally use to close a tab dissapears off the right.  See attached picture.  The only way to restore it seems to be to restart the browser.

Reproducible: Sometimes

Steps to Reproduce:
Haven't found a way to reproduce it reliably.

Does it also happen in Firefox's safe-mode?

I've started firefox in safe mode now, and will post here if it happens again.

Michael, the point of safe mode is to determine if an extension or thems is causing the problem (safe mode disables both of these), not to use indefinitely.

Although this has happened to me several times, I haven't figured a way to reproduce it reliably.  I also can't waste hours trying to get it to happen in safe mode.  So the only real option for me is to run the browser in safe mode for a few days and see if it happens again (so far it hasn't).  The only extension that I use is the google toolbar.  If, after running for a week in safe mode, this hasn't happened again, I would sumise that the chances are very good that it relates somehow to the use of the google toolbar (which is widely used enough to make this quite serious, whether the fault lies in the toolbar or with firefox).  Shouldn't this bug be kept open until  we can figure out a little more?  There's definitely a bug somewhere, after all...
