Adobe flash plugin keeps crashing. Please help!


So my adobe flash plugin apparently keeps crashing and this has been going on for awhile now. When I watch videos on youtube, the audio will stutter. Sometimes the video will crash too and whenever I watch a video on teennick.com, the video is constantly freezing and/or crashing. I've tried using the 'safe mode" version of firefox and the problem still happens. This is so frustrating, someone please help.

Chosen solution

acidhead, Thanks for reporting your solution to Flash lockups, which included reinstalling the Flash plugin after first doing a complete uninstall, including manual removal of leftover Flash files and folders.

For the benefit of others reading, Adobe includes instructions for uninstalling Flash on Windows in their own help article (linked from the Flash Plugin - Keep it up to date and troubleshoot problems Firefox article) which is:

If adobe flash player keeps crashing why can't firefox fix the problem? I'm a bit computer illiterate and don't understand half this stuff that's posted on how to fix the problem and don't want to leave my computer unprotected or mess things up worse!

Hi mtjensen5, Mozilla is working on a replacement for the Flash plugin (Shumway), but that won't be ready until some time next year and probably won't be perfect until, well, it might never be perfect. Until then, we're stuck with the plugin Adobe provides.

The Flash Player's protected mode feature does have theoretical security benefits because it splits up Flash applications into separate compartments so that it is more difficult for a malicious Flash application to infect another one. But... on some systems this feature makes Firefox unusable on sites that use Flash, so if you want to keep using Firefox, and keep using Flash in Firefox, I don't think you have much choice but to disable the protected mode feature.

I been running Firefox and experiencing NO problems with flash player crashing! Why you might ask? Simple I wrote a script, compiled it to an executable and ran it in windows task scheduler every 15 minutes to delete the following files:




I see the same people posting solutions that same stuff over and over and over to all these people having this same issue, and find it funny they keep posting this like safe mode, hardware acceleration, update, reinstall, and most of the time it don't work and SO MANY people are facing this issue.

Do you really think posting the same thing so many times is helpful when so many are having this issue? Not really! It just bumps your number up, that's all.

I will share my script with everyone and they can report back to see if this resolves their problem, but first a quick overview of what to do.

First the script clears out all temp directories I made for this installer, and then recreates them in case you run it multiple times. The same goes for the folder it creates under C:\Programdata\scripts\Delete_prefetch.exe

There is a simple executable in there made in AutoIT that preforms the following deletions mentioned above.

When you run the installer i have a link below, you will see a cmd window appear and disappear quickly, followed by a folder appearing on your desktop called " Firefox_Flash " in that folder is an xml file which is what you import into task scheduler, a readme file for SIMPLE instructions to import it, and a picture of the import process that is mentioned in the read-me file. You will have to either modify the XML file , which is super easy in windows 7, or make the changes while importing it as it shows for my machine and username. Unfortunately I don't know how to make this so you don't have to modify it.

I am sharing this with everyone so people can stop dealing with the headache.

So is this a Firefox or Adobe problem? Well, each one will point the finger at the other, however, i am hoping since i posted this here Mozilla will take the initiative and look at what i found ... hint , hint..

PLEASE NOTE: this is for win 7 64 and 32 bit systems. It may work on win 8 64 bit, but untested.

Not sure whether or not it worked. After editing the script, I was denied access from saving it. Even when I imported it, the author name had not changed to my name after editing it? Is there a way of testing it to see if it works or not?

Carm 6 solutions 132 answers

Alternatly you can just create a task:

1) On the general tab: a) call it whatever you want b) Run only when user is logged on c) Run with Highest privileges

2) under the triggers tab: press the new button at the bottom

3) In the new triggers window: a) Begin Task On a schedule b) check the one time radio box c) Create a start date in the past & check sync across time zones d) Delay task for one minute e) Repeat task every 15 minutes f) for the duration of: Indefinitely g) Press OK

4) under the actions tab press the NEW button

5) Under New action a) Start a program b) under setting browse to: C:\ProgramData\Scripts select:

Delete_prefetch.exe c) Press OK

6) Under Settings tab a) UNCHECK the box that says Stop the task if it runs longer than : b) Press OK

NOTE: You will see your task when you highlight " Task Scheduler

Library " and you should see it

I made some changes in the instructions and hopefully people will not have to edit the xml file as i have made it so that your hostname (computer name ) and username are inserted in the file .

Once again a folder will appear on your desktop called "Firefox_Flash" after you see to quickly appearing and disappearing cmd prompts.

The pdf now as visual pictures on what to do, hopefully, this will clear up some things and make it easier. This will work on 32 and 64 bit systems on Windows 7. Windows 8 is untested but should work?

The script does not work. We may as well accept it, Adobe Flash is just not compatible with Mozilla Freezefox.

I am finding out this is a flaky issue, i have had 100% success with a basic install, now im not saying it will fix everyone's, flash issue. Mine was intermittently crashing, but someone else who i worked with for over an hour had it crashing upon start up and that didn't fix it.

By the way if you want to undo what that did , open a cmd prompt and type or copy paste these commands in:

rmdir "C:\ProgramData\Scripts\" /s /q

SchTasks /Delete /TN "Clear Firefox Prefetch" /f

fyi if you get a " ERROR: The system cannot find the file specified. " after running the second command that means the fix was never properly implemented. ( i have properly automated this thing since the original posting )

Best Regards

I have enough of Flash crash, could you send me your fix?


Carm 6 solutions 132 answers

I have chosen to go public with my solution as i have had a few users benefit from my methods. Notice i said methods, as there are two completely different solutions to all the canned responses that everyone keeps slinging out.

All you have to do is click my name on the left and there will be a blog link in which i laid it all out for everyone.

Sorry for the late response, the answer is yes updates are irrelevant to what my solutions do. Click on my profile and in there is a link to a blog i created and laid everything out. There are two possible solutions.

As far as windows 8, from what i have seen it should work as the directory structure is the same. I personally do not have windows 8. the fix will work on 32 or 64 bit platforms. When you read the info in my blog, you will find that there is nothing that my script can do to create any ill effects on anyone's machine.

@KevinM333 Try disabling the plugin-container.exe

I find it interesting that none of the other browsers suffer with flash player like this to be honest and its clearly a Mozilla issue not adobe is what i think, more specifically the plugin-container.exe.

Go here:


go to where it says disable plugin container. All the information is in my blog posting. Instructions, links, videos on how to. The whole thing takes 2 minutes max to implement and very easy to do and undo.
