Status: VERIFIED INVALID

(Firefox :: Extension Compatibility, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; ca; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)

In the last two weeks I found out that a lot of pages containing flash elements get the content disappear when I switch tabs and then switch back, or when opening a new firefox window. 
This sometimes happens in youtube but not always, what makes me think it may be a problem caused by adds on the pages.

The problem only resolves when reloading the tab. But the problem is only visual, because if in the page was some kind of sound or music played, it's still played when switching back to it, but nothing can be seen.

Reproducible: Always

Steps to Reproduce:
1. Open a web page with flash elements (maybe only happens with adds)
2. Open a new tab or window
3. Switch back to the first tab/window
Actual Results:  
All the content in the page is disappeared, although sound can still be heard if there was any.

Expected Results:  
The page should still be visible.

It doesn't happen in youtube, nor with a web I made including a flash element I created.

Can you please run Firefox in Safe Mode to check if no extension interferes here? See http://support.mozilla.com/kb/Safe+Mode. Thanks.

Ok, I think the problem really lays in one extension, the RealPlayer Browser Record Plugin. When disabling it everything seems to be all right.

Thank you for the advice and sorry for the time.

You should get in contact with the developers of that extension and pointing them to that bug. Thanks.
