User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b13pre) Gecko/20110303 Firefox/4.0b13pre

I could reproduce this issue with Flash player version 10.2.152.26 and 10.2.152.32 in Windows XP and Windows 7 in safe-mode and new profile. Chrome hangs a bit, but does not crash and Opera does not hang or crash.

I tried disabling hardware acceleration in both Firefox and Flash players, but did not helped.

Firefox starts hanging for few seconds then later plugin will crash.

Reproducible: Always

Steps to Reproduce:
1. Open http://www.thedailyshow.com/full-episodes/mon-march-7-2011-rand-paul and click on play.
2. While video is buffering move time bar forward, example 8:00
3. Click on pause and play very fast.
4. While video is buffering move time bar backward, example 1:00.
5. Click on pause and play very fast.
6. Repeat step 2 to 5 continuously fast until Firefox start hanging.

Now this is the hard part to reproduce:
7. With firefox hanging keep repeating steps until Flash player crash.

This issue is based on timing and I could not find a correct timing to reproduce. Sometime you may need 30min to get a plugin crash, sometime not.

These are all hangs where Flash stops responding for 45 seconds. From what I can see, the Firefox behavior here is correct, and Flash is actually hanging.

In several cases here, it appears that Flash is using wininet calls such as HttpSendRequest, which appears to be a blocking call. If Flash is making blocking networking calls on the plugin thread, this is the intended behavior.
Is this still an issue in Flash 10.3?

Looks like a dupe of bug 567645. Do you have the same regression range as pointed out there?
