Question

Flash is crashing Firefox constantly

FF was acting normally all day, including YouTube. I viewed some instructional videos, and they played fine. Then in the evening, I went to YouTube, and FF started crashing constantly. Sometimes a video would play for a few seconds before crashing, other times FF would crash as soon as I clicked on something. I changed absolutely nothing, no settings, nothing since when it was working fine earlier in the day. Sometimes it crashes even when I'm not playing any video. I assume that some video on the site I'm on probably started automatically (ads).

I've been looking through tons of questions, threads, etc. for the last two days.  The only thing I can find is that it's probably related to Flash. I've uninstalled it (v17), reinstalled v18, hardware acceleration is off, Windows updated, etc. I can't find anything else to try.  FF works in Safe Mode (obviously no video plays), and Chrome plays video just fine.  The only way I can use FF is to disable Flash, or use it in Safe Mode.

Below are the crash reports.

Isn't this because Firefox has disabled Adobe Flash?  I can't watch a single video on YouTube or Creative Live.

Best forum post ever.  Thanks for the details. 


Mozilla's crash-stats site is being crazy slow at the moment, but I got through half of these.  These are *all* weird internal Firefox crashes, and nothing I'm used to seeing in terms of Flash Problems.

These all look like they're bunched pretty closely together.  If this just started up and you haven't rebooted yet, I'd start there.  I'm guessing that the machine is just in a bad state from how weird this looks.  If that's not it, I think I'd run a good anti-virus/malware scanner after that.  http://www.malwarebytes.org/ is free and well respected.

If you're still stuck, just update the thread and I'll take a deeper look, but this is the weirdest collection of crashes I've seen in a while.

Thanks for the reply, but I've already done all that.  In troubleshooting, I've rebooted many times.  I've had Malwarebytes since last October, and I've been running that and Webroot with no problems.  The weird thing is that everything was fine, then I do the exact same thing two hours later and FF starts crashing constantly.  I've found that LastPass (which I've been running for over a year) is possibly part of the problem.  I can run LP or Webroot with no problems, but the two of them together suddenly is causing an issue. I seem to be able to run only one or the other, but they've been running together just fine for over a year.  If I have Flash disabled, I don't have crashes either.

Oh, and I already have Malwarebytes Support working on it to see if there's a virus that isn't being revealed in the Malwarebytes scan.
