User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.15) Gecko/20110303 Firefox/3.6.15
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.15) Gecko/20110303 Firefox/3.6.15

Using the Control/Tab keyboard shortcut, occasionally Firefox will zoom in significantly. It's at random and very strange, but very annoying as i have to command/0 to reset the sizes back to normal. 

Reproducible: Sometimes

Steps to Reproduce:
1.open firefox with multiple tabs
2.press control tab at the same time to attempt to switch tabs
3.repeat step 2 until desired (undesired) result/glitch
Actual Results:  
strangely, it was happening almost ever twenty or so tab switches, but now i can't recreate it with the current open pages. i wonder if it has anything to do with what windows are open and what code/etc they have..


feel free to email/call. i'm glad to help as this is a significant bug and extremely annoying.

I'm similarly having odd zoom behaviour when pressing the control key. I'm utterly unable to reproduce it as it happens sporadically, both when switching tabs as well as closing tabs with ctrl-w.

I've not seen anything specific in common on the pages where this happens but perhaps those better familiar with what's underneath the hood might be able to figure that out.

I'm similarly available to help track this down. Annoying it is, indeed.
Is it possible that the reason why you sometimes see this bug and sometimes don't due to bug 767197? Can either of you test whether the behavior you see seems related to recent scrolling?
