Uhm, bp-e939b2dc-8b8e-4926-82fa-8bfd72140622 (sorry for the noise).
No crash on my firefox:
User Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:32.0) Gecko/20100101 Firefox/32.0

I am also getting a lot of crashes, different  signature though

Thanks, it looks like the async readers changes (bug 979104) have caused some breakage and/or revealed some latent issues.

annaeus, would you mind filing a new bug for your crash, please?  It may end up being related, but as you pointed out, it does have a different crash signature.  Thanks!
Ok, filed bug 1028742
Depends on: 1028748
Depends on: 1028144
Hopefully fixed by bug 1028144.
Status: UNCONFIRMED → NEW
Ever confirmed: true
This crash (and also the one in bug 1028742 which I also saw before sometimes) seems to be no longer reproducible in the latest Nightly, so it looks like it's fixed! (although I can't figure out how to update the bug metadata to indicate this)
Same, no crashes for me so far. 

However the video seems to freeze (stops and never resumes playing) when buffering is triggered. Are there any bugs about that?
Thanks for confirming, I'll close this as fixed by bug 1028144.

Could be bug 1024858, I'm working on a fix for this now.
