Hello Guys,

My name is Hilmi, I'm having problem viewing non-html5 video as it will always show error adobe flash plugin crash everytime I try to play the video. I am using Dell Inspiron 5400 laptop, adoble flash player 20 NPAPI, mozilla firefox 43.0.1 and windows 7 SP1.

I found one discussion most similar to my issue and they gave instruction to disable hardware acceleration by right click on flash picture in website: Flash Player video playback issues, but the flash picture itself failed to load.

My system restore is not available as there is no restore points has been created. one of the website that i have issue playing the video is http://www.gogoanime.com/dragon-ball-super-episode-24

kindly need assistance from you guys as i dont know what to do to solve this problem anymore. i have tried to uninstall/install flash player and updating my firefox but the error still persist.

Thank you.

Hello guys,

I have finally solved the crash issue and now I can play Non-HTML5 without crashes anymore!! After you said the plugin container might be the cause, I noticed there is no plugin container running in task manager. So I googled about plugin container crashed issue and found solution from this page: Plug in Container and Flash Crashing Issue | Firefox Support Forum | Mozilla Support

The cause is actually due to the protected mode feature of the Flash Player plugin where we need to disable it so the plugin container will not crash anymore. I quoted from the page:

This worked 100 % Thanks!

Hi nonsaya, thank you for that.

A common problem on Windows Vista and higher is incompatibility with the protected mode feature of the Flash Player plugin. I recommend disabling it.

See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

Or if Windows gives you problems with permissions, try this way:

(1) In a My Computer or Windows Explorer window, open this folder:

C:\Windows\SysWOW64\Macromed\Flash

If that folder does not exist, then you are using 32-bit Windows, and you can open the following folder instead:

C:\Windows\System32\Macromed\Flash

(Note: This folder exists on both 32-bit and 64-bit Windows, but on 64-bit Windows Firefox uses the Flash player in the SysWOW64 folder instead.)

(2) Check for a file named mms.cfg:

Note: If you do not see file extensions such as .ocx, .dll, .exe, and .cfg on the files in this folder, then Windows may be hiding these from you. In order to work with file names accurately, it is best to unhide the extensions. This Microsoft support article has the steps: http://support.microsoft.com/kb/865219.

(A) If mms.cfg exists, drag it to your Documents folder where you can edit it without being bothered about administrator privileges

(B) If mms.cfg does not exist, open your Documents folder, right-click > New > Text File and name the new file mms.cfg

(3) Open mms.cfg from Documents into a text editor such as Notepad.

Add this on its own line (I put it last):

ProtectedMode=0

Save the file and close Notepad.

(4) Hold down the Ctrl key and drag the mms.cfg file back to the Flash folder to make a copy there, keeping the original in Documents

This change will take effect once the Flash plugin is completely unloaded, which may require exiting and restarting Firefox (allow a few minutes for all the Flash processes in memory to terminate after exiting Firefox). "


Flash Player Protected Mode on 32-bit Firefox is an important defense against malware.  You significantly increase your risk of infection by disabling it.

You would be far, far better off moving to either 64-bit Firefox for Windows, which includes a native NPAPI plug-in sandbox (we use Firefox's sandbox instead of the one we had to retrofit to 32-bit Firefox), or to another browser.

You can find the 64-bit Firefox Beta here: https://www.mozilla.org/en-US/firefox/beta/all/

Don't forget to right click ans run as administrator, or they will not delete

I have downloaded the del_prefetch.cmd and run it as administrator, but it keep showing waiting for 30 seconds.

After that I close the file and tried to play Non-HTML5 video in Firefox but still unable to load.

Actually there is no flash player plugin in my Firefox as I downloaded the installer using internet explorer. Do I need to re-download installer in Firefox?

It is designed to loop like that! It will keep prefetch files clear, let it do its thing and minimize it, right click and run as admin. You can change the time period if you right click and choose edit, and change it to whatever you like. You will see the timeout period when you right click edit that file, then save.

Yes you need to re-download the files again. If you go back to that link , and click parent folder, it will bring you to a menu and you will see a folder called BAT version. you can get this one downloadFlash_XPandUP.cmd and right click, run as admin, this will preform the clean install of all the flash player versions for you,


Then run that thing that runs in a loop and then launch Firefox. Remember just minimize the thing that runs in a loop

I am going to chime in on this as I have found some relief.

I have been crash free as far is this issue.

I implemented a small program which keeps certain prefetch filed deleted. Now I know what some are saying what does this do and how does it help? The answer is I am not entirely sure. I kind of stumbled upon this while troubleshooting the issue. All I know is that i have been crash free since i use something like this myself for several years now.

I have a bat file if anyone wants to test it that just runs in a loop:

@echo off

:start

del C:\Windows\Prefetch\PLUGIN-CONTAINER*.pf >nul 2>&1

:: remove the >nul 2>&1 if you do not want to see messages like files does not exist for example

del C:\Windows\Prefetch\flashpl*.pf >nul 2>&1

del C:\Windows\Prefetch\firefox*.pf >nul 2>&1

del C:\Windows\Prefetch\PLUGIN-HANG*.pf >nul 2>&1

del C:\Windows\Prefetch\AGCP*.pf >nul 2>&1

timeout 30

goto :start

Firefox is the ONLY browser with this issue and i believe it is 100% related to the plugin-container.exe/NPAPI that they use.

I attempted to post this on the forums and some people were willing to try it and most have had success.

There is zero risk deleting these prefetch files

I do have an exe that sits in the system try and runs all the time as well. making and running that bat file should be a good acid test to see how many this has helped or not.

As far as I am concerned this is 100% a Firefox issue, and until they nuke the plugin-container.exe/NPAPI the problem will always exist unfortunately. I will provide my exe that will run in the systray to those who are interested

I thought I would offer this up here in these forums in hope there are some much more tech savvy and open people to do testing and understanding of this issue. If it proves useful maybe this could be built into the NPAPI flash player..

Anyways my 2 cents

Best Regards

Hello Carm01,

Where can I download the bat file? I'm interested to test if it works for my issue.

Thank you.

You can grab it here

It will run as long as you want it to

its called del_prefetch.cmd

I can't say it will fix your issue, but could very well as i had great results with every machine I used and re-imaged.

Please work through the video troubleshooting guide.

https://helpx.adobe.com/flash-player/kb/video-playback-issues.html

If you're still stuck, please follow the directions in the guide on providing the dxdiag report and additional information about what you tested and saw.

Thanks for your reply jeromiec83223024. I have worked through the troubleshooting guide just now. I can play HTML5 video but Non-HTML5 video crashed.

I was not able to disable hardware acceleration because flash logo also crashed.

I have added Bug 4102779 in adobe bugbase. Hopefully the issue will be solved soon.

Thank you.

Okay, it's probably not hardware acceleration then.

Here's what I'd do:

  • In Firefox, go to Help > Restart with Add-Ons Disabled
  • Try something that Flash currently crashes on. 
  • If it starts working, it's something to do with another plugin in Firefox. 
    • You'll basically just have to disable them temporarily all and re-enable them individually until the crash comes back. 
      Once you've identified the plugin, we can take a look and see what options are available to mitigate it from our side, if any.

If running Firefox in safe mode doesn't resolve the issue, then I'm guessing your Flash installation is damaged.

The first thing I'd do is check for and repair any issues with the local filesystem.  It's always a good idea before doing disk maintenance to make sure that you have good backups of anything critical on the machine.

Check your hard disk for errors - Windows 7:

https://support.microsoft.com/en-us/kb/2641432

Once any problems are fixed, I'd manually remove Flash Player.  This will expose any issues with corrupted/inaccessible files that might otherwise be masked during the automatic installation/upgrade process.

Performing a Clean install of Flash Player on Windows:

https://forums.adobe.com/thread/928315

If you're unable to complete all of these steps and it's a file involved, then we know that there's some filesystem corruption.  This might just be a random thing -- poorly timed power outage, solar flares  , etc -- but it might also be an early indication that your hard disk is on the way out.  Again, a really good reason to make sure that your backups are up to date.

Unlocker is my go-to utility for fixing files that I can't delete on a system:

http://download.cnet.com/Unlocker/3000-2248_4-10493998.html

If it's a registry key that you're unable to remove, then you have a bigger problem.  There are some commercial utilities that advertise their ability to fix these kinds of problems, but Windows already automatically scans and repairs the registry.  I can't recommend any of those products specifically, and personally, that's generally my queue to think about reinstalling the OS.  If it's been a few years, jettisoning all of the junk that has accreted in the registry and removing the fragmentation that occurs over time makes the system run much faster than you've probably gotten used to.  You might think about moving to 64-bit Windows 7 as well, since you have a 64-bit capable machine.  The vast majority of Win7 users are on 64-bit, so offerings from vendors are tested more on the 64-bit OS across the board.  As an aside, Windows 10 is supposed to solve the vast majority of this kind of registry-related pain.
