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
In this excerpt from
Answercast #101, I look at an installation of Firefox that is crashing while

Flash crashes in Firefox
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
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.
Try to fix Firefox
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.
Reinstall fresh programs
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
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
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
Reinstall your addons last
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
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
