374005 - Using tabs with "Show the New Tab Button on Tab Bar" crushes all tabs to far left

Status: VERIFIED WORKSFORME

(Firefox :: Tabbed Browser, defect)

Description

[Dustin]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2

I experienced this bug when first starting up Firefox 2.0.0.2. Upon hitting Command-T for a new tab, all of the visible browser windows were pushed to the far left 1/2" of the window. All that was visible was a very thin column of the new tab, the New Tab tab bar button, and next/last tab buttons. Upon turning off the "Show the new Tab Button on the tab bar" in Preferences -> Tabbed Browsing -> Display Options, the tabs were able to stretch out to a usable size. I wish I could affix a screenshot...

Reproducible: Always

Steps to Reproduce:
1.Go to Preferences -> Tabbed Browsing -> Display Options
2.Select "Show the new tab button on the tab bar"
3.You may not even need to create a new tab for your visible browser window to get pushed to the far left, leaving a large, white, unusable space.
Actual Results:  
The active browser tab was pushed to the far left of the screen.

Expected Results:  
Opened a new tab, without pushing all tabs to the far left.

Reporter, are you still able to reproduce with a more recent build of Firefox? If not, could you please resolve this bug WORKSFORME? Thanks.

I'm now using version 2.0.0.5 and it's still happening. Screenshot now attached.

Dustin, can you reproduce this with a new profile? This looks like a problem with an extension.

I created a new profile and was not able to reproduce the bug.

Dustin,

This is likely due to a problem extension. Feel free to go through and determine which extension is causing the problem by disabling them one by one or by migrating files to the new profile and seeing which file caused the problem. If you don't wish to do either of those, please close this bug as WORKSFORME.
