Description

[Jordi]

User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1
Build Identifier: Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1

When loading Firefox with saved app tabs it loads a default 'normal' tab to keep browsing.

If this tab is closed a strange behaviour moves the URL panel upwards overlapping the tabs panel.

Reproducible: Sometimes

Steps to Reproduce:
1. Load Firefox 4.0.1
2. Create some app tabs
3. Close Firefox
5. ReLoad Firefox
3. Close default created tab

Actual Results:  
The URL bar overlaps the tab bar

Expected Results:  
The tab panel and URL panel should keep the same distances.

Can you please test in safe mode, just to make sure that no extension is causing this issue? Thanks.

Hey

Sorry, you're right, With Safe mode the issue does not appear.

I mark the issue as INVALID because this is no Firefox Problem.

Jordi, thanks for the feedback. It would be great if you could check which extension has been caused that. Simply disable the installed ones step by step. Once you have found the right one, you could inform the extension author so it can be fixed.
