Helping people with computers... one answer at a time.
Flash crashing in Firefox means something is wrong with either Flash or Firefox. We'll take an investigative approach to get running again.
Running Windows 7, Home Premium with Firefox 18.0.1 and Adobe Flash 11. Adobe Flash does not work in Firefox probably 90% of the time. However it works fine in Chrome and IE. On Firefox, which is my usual browser, when clicking to play a YouTube video or any other video on any other website, the following is displayed: "The Adobe Flash plugin has crashed. No report is available. Reload the page to try again." Reloading the page of course has no effect. Firefox, Windows and Adobe Flash are all up-to-date. This is driving me nuts and I really hope you can help. My computer man says his crashes all the time too.
In this excerpt from Answercast #101, I look at an installation of Firefox that is crashing while watching videos.
Well, there are two approaches to this problem. There's the practical approach, which you're probably not going to like, and then there's the investigative approach.
The practical approach is... well, you know what? If it's working in IE and Chrome, use IE or Chrome.
Clearly, things are working there - just avoid the problem rather than fixing the problem.
Now, as to why it's crashing in Firefox? That's the investigative approach. Let's take a look and see what is going on in Firefox.
The very first thing that I would do is actually disable all of the add-ons in Firefox. That may happen to disable the Adobe Flash add-on, which you can then re-enable to test out whether it's made a difference.
If it hasn't, what I would actually do is uninstall Firefox completely; uninstall Adobe Flash completely. I would even potentially go so far as to use Revo Uninstaller to make sure that "completely" really means completely.
Then, I would reinstall Firefox from scratch. I would download the latest Firefox and install it. Then, before installing any of the plug-ins you might have, I would immediately go to a site like YouTube and try and watch a video.
It will prompt you, saying, "You need Flash for this." See if, at that point, a fresh installation of Flash into a fresh installation of Firefox might work. My guess is that it will.
Either of two things will have happened:
Either there was just something wrong about the Firefox installation;
Or the Flash installation was manifesting as a crash when you tried to display video in Firefox.
We don't know which it is, but we do know that a clean reinstall cleared it up.
The other thing that might happen is - as you now go back and add the various add-ons you had in Firefox, one of those might cause the problem to reappear.
I suggest that you be very careful about how you go about reinstalling your add-ins in Firefox. In fact do them one at a time... very carefully - making sure to try a video after each one.
If after installing a plug-in the video starts failing in the way that
you've described, well, then you know it's that plug-in's fault. Don't use that
