(Firefox :: General, defect)

Description

[Bogdan Maris, Desktop Test Engineering]

Reproducible on the latest Nightly (BuildID: 20150120030203):
Mozilla/5.0 (Windows NT 6.1; rv:38.0) Gecko/20100101 Firefox/38.0

Steps to reproduce:
1. Launch latest Nightly with a clean profile.
2. Visit a youtube page which has an ad. (eg: https://www.youtube.com/watch?v=fhcZ6b2FSsk)
3. Open another video or the same one in a new tab and enter full screen.

Expected results:
The video is displayed with no issues.

Actual results:
While the video is in fullscreen the ad from the first tab can be seen over the video..

Notes:
1. This issue is a regression

2. Not reproducible in Mac OS X and Ubuntu only on Windows.
3. If the video from step 2 does not contain an ad visit another one randomly until the ad appears. It is not important if the video from second tab contains an ad or not, it is reproducible either way.

Bogdan, can you give us an example URL for step 1 that reproduces this?

I don`t quite know what information you requested here. In step 2 I added a link which does contain an ad (sometimes it does not, if so, chose another one randomly until you hit one that contains an ad).
