(Firefox :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b12) Gecko/20100101 Firefox/4.0b12

I just recognized that when i go to Firefox's About Menu and click on the "Get involved" Link the new Pop-Up Window cuts the Edges of the Firefox-Tabs that are opened in this new Window.
No 3rd Party Addons are running while testing this Bug.
It seems that this occurs only with this Pop-Up Window, maybe a few more people can check that with other Pop-Up's.

I made 3 Screenshots to demonstrate it for better understanding (:
(Look at the left Top Corner)

1. Normal Firefox Window with correct positioning

2. About Dialog Box

3. Cropped Top of the Browser Tabs after clicking "Get involved"

Reproducible: Always

Steps to Reproduce:
1. Go to Firefox Icon in the left Corner
2. Go to Help -> About
3. Click on "Get involved" Link
4. Check the Left Top Area in the previous Window and the new "Get involved" Pop-Up Window
Actual Results:  
The Window looks cropped at the Top

Expected Results:  
The Window should look like the normal Firefox Windows where the Tabs aren´t cropped

I am working on an Screen Resolution of 1920x1080 (Tinypic rescaled my Screenshots somehow...can´t turn it off sorry)
