Flash plug in causes Firefox 4.0.1 (on Vista Business) to hang

Flash plug in causes Firefox4 (on Vista Business) to hang, on sites with flash content (videos, etc)
I tried everything I found in firefox forums (uninstalling - reinstalling the plugin, disabling hardware accelaration, etc ), but it was useless
I tried installing Firefox 5.0b2 and I have the same problem: with the flash plug in activated, I get CPU usage up to 100% and Firefox hangs...

Make sure that you allow the plugin-container process in the firewall.
You can try to disable the hardware acceleration in the Flash Player.

The Flash plug-in causes Firefox to crash for about 2 minutes every 20 seconds, it is the newest Flash update. It has happened to me both with Firefox 3.6 and 4!

Firefox for me has been fine for the past couple of years or so. Then all of a sudden about 5 months ago, everytime i would use Firefox it would crash after browsing for about 1 minute. I uninstalled and reinstalled numerous times to no avail. I then got sick of the problem and then used IE till now.
However, i heard about Firefox 4 and thought maybe this would fix it. Unfortunately, the same problem occurred! I then heard about being able to start Firefox with add-ons disabled to find any sources of problems, and i've found that the cause if Flash! It is the newest version and always has been, so i don't know what i can do, since Flash is important for most websites nowadays!?

Could you please do the following.
Download the following two files and save to your desktop. These are direct download links so you'll only see the dialog boxes which looks like the ones you see in the screenshot.
* [http://download.macromedia.com/pub/flashplayer/current/uninstall_flash_player.exe uninstall_flash_player.exe]
* [http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe install_flash_player.exe]
Next, close Firefox via File | Exit (''it's important that you do it this way and not just by clicking the close button'')
Next, double click the '''uninstall_flash_player.exe '''file you downloaded earlier and then '''reboot'''. A reboot is necessary to remove the setting from the Windows Registry.
Next, double click the '''install_flash_player.exe''' file to reinstall Flash.
Finally, restart Firefox and see if it made any difference.

Make Flash Plug-In for Firefox Remember Privacy Settings for Camera and Mic Access on Local File

My company is using Flash Player to develop some kiosk-style applications to run on a standalone computer (no network connection). This computer will contain web pages containing Flash content. They will be opened from the local HD with Firefox with the Adobe Flash plug-in (v11.7.700.224). One of the applications accesses the microphone hooked up to the computer. When this application is started, it always asks for permission for "local" to access the microphone and camera. In previous versions of our system, we could click "Remember" if we did it once and that would make it so it wouldn't ask for permissions again (in this case, the Remember option isn't available, and the site settings don't even offer the Privace tab). However, in the previous case, we were running IE with a previous ActiveX Flash version (unfortunately, this approach is no longer available as we have had to switch to Windows 8 and that changes the game with IE and Flash entirely).
At this point, we have tried to use the Global Settings for "Camera and Microphone Settings by Site..." to enter "Local" as an always allowed site. This does not seem to have any effect. We also tried entering the root directory of the applications in "Trusted Location Settings", but that also seemed to have no effect.
I'm not sure what has fundamentally changed here. I think there might be some differences in the Plug-In version (compared to ActiveX), but I'm not sure what they might be or how to do the same thing as before.
Any help would be appreciated. Thanks in advance.

Chris,
We learned that the Privacy tab (in Settings) can be found under the Flash plug-in for Firefox, but only if Firefox is running under an administrator.
Unfortunately, we haven't had much luck with the mms.cfg file. The following was used in the mms.cfg file (placed in both the %WINDIR%\SysWow64\Macromed\Flash and %WINDIR%\System32\Macromed\Flash” directories):
AVHardwareDisable = 0
AVHardwareEnabledDomain = local
AVHardwareEnabledDomain = 127.0.0.1
AVHardwareEnabledDomain = localhost
AutoUpdateDisable = 1
The AVHardwareEnabledDomain settings seem to be getting ignored regardless of whether the user is a standard user or an administrator. I also checked to make sure it wasn't just a local problem by going to a website that uses a microphone (http://www.testden.com/accent-reduction/systemcheck.htm). Adding the requested domain to the list (AVHardwareEnabledDomain = train.act360.com) still didn't bypass the allow/deny dialog box.
We know that the mms.cfg file is being read because setting "AVHardwareDisable = 1" will result in no prompt and that section being greyed out in Global Settings. I saw a post that suggested this setting was required to even make the AVHardwareEnabledDomain work, but it seems to block the local entirely and still brings up the dialog query on the internet site.
Thanks,
Torrey

Adobe Flash XI repeatedly causes Firefox to crash

I'm running Firefox 20.0.1 on Windows 7. Flash XI frequently, but not always or consistently, causes a particular website to crash and sometimes causes Firefox to stop responding. Sometimes when Firefox stops responding I have to use the Task Manager to shut it down; other times it starts responding after a few seconds. The website is an important one I visit daily so there may be others I'm not aware of. The problem began two or three months ago (I always install updates). I can't force t to happen. When it happens I can get one of two prompts: "A script on this page... or A movie on this page... is causing Flash to run showly" followed by the options of waiting or stopping the script. Any suggestions?

Install Flash Player in Safe Mode.
Shut down the computer.
Press the power button. Immediately after you hear the startup sound, press and hold the Shift key.
The Shift key should be pressed as soon as possible after startup,but not before the startup sound.
Release the Shift key when you see the Apple logo on the screen. Startup will take longer than usual.
Login to your account. Launch Safari.
Enter this address in the Safari address bar manually. Click Enter.
http://get.adobe.com/flashplayer/
Follow the prompts. Install Flash Player.
Once done, quit Safari and restart the computer from  in the menu bar.

Flash Plugin is causing Firefox to freeze

Recently, all of my browsers have been acting up. I use Firefox mainly, but ever since this issue started popping up, I tried Chrome and IE and the same thing is happening there as well. Every time I load up a page with flash on it, the flash plugin crashes, causing my browser to freeze up for 30 seconds up to a minute (I get "Not Responding" at the top too). If I uninstall Flash from my computer, I have no problems at all, but the second that I re-install Flash, everything goes haywire and doesn't work anymore. Even when I reload the page, the plugin just crashes again immediately. I currently have Flash 10.3.181.34 installed. Running XP, and FF 5.0.1

Please upgrade your browser to Firefox 8 and check

Adobe plug-in causing Firefox on Mac to crash?

Firefox started crashing recently on my Mac, perhaps after I recently upgraded Firefox. This morning I updated Adobe Flash, and reinstalled Firefox, but it's crashed several times since then. It seems to crash while loading pages that contain moving images.
I've tried turning off Hardware Acceleration in the preferences, but that hasn't helped.
I've gone to the same web pages with Chrome and Safari, and neither of those have crashed.
I am using Firefox 37.0.1, MacOS 10.8.5, and Adobe Flash Player 17.0.0.134.
I opened a new tab in Firefox and typed "about: crashes", and will paste the five most recent crash report ID numbers below.

Any help you can give me would be great - Firefox is my preferred web browser, but this is getting problematic.
Thanks,

Having more than one version of a program may cause issues.
Grab the uninstaller from here:
'''[http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html Uninstall Flash Player | Windows]'''
'''[http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html Uninstall Flash Player | Mac]'''
Then reinstall the latest version.

Abode Flash Plug-in blocks Firefox when I am on youtube

Hi, Firefox crashes every time I watch something on Youtube (I noticed that the problem is connected to Adobe Flash). Maybe I don't have some program because I re-booted the computer, and before the boot everything was fine. I have Windows XP 32 bit.

Well, first thanks for the quik response. I didn't find it because Firefox isn't really crashing but it blocks. If I open a youtue video (on youtube page) and quickly open a new window with another page I can listen to the song but when I click on tthe youtube page... Block! ( I can watch youtube's video on social networks!)
Sorry if I used "crash" instead of "block".

Flash Plug-in crashes Firefox/Safari, Mac OS 10.7

I have had trouble with the Flash Player plug-in crashing after I upgraded to Mac OS 10.7 a few months ago. I have the latest version of flash player (version 10.3.183.10). I uninstalled and re-installed Flash Player. I also brought the computer in to the Apple store for servicing. The people at Apple believe the problem is with the Flash Player. I have re-installed the Mac OS 10.7 operating system as well without any luck. Any help would be greatly appreciated.
Neal

Sorry, I know nothing about Macs, but I'll try to give you a suggestion anyway.
Does the crash also occur when you go to http://www.adobe.com/software/flash/about/ or http://kb2.adobe.com/cps/155/tn_15507.html http://forums.adobe.com/thread/891337?
If not, can you try to disable Hardware Acceleration (http://forums.adobe.com/thread/891337) ?

Adobe Flash crashes, continually causes Firefox 13.0.1 to crash

Firefox continually crashes (approx. 6-8 times a day or more) due to Adobe Flash player crashing.
I'm running Firefox 13.0.1 and Adobe Flash 11.3.300.262
I noticed that since the second-to-last update of Flash Firefox has been crashing a lot. Before that Firefox crashed 'only' once a day or so.
Over the past few months I've read just about every thread related to Flash & Firefox and I'm not about to spend hours troubleshooting stuff, trying to disable hardware acceleration, etc, etc. I've done that before when the Flash-crash issue started a couple of months ago. (Also, Firefox is sometimes sending you automated crash reports, so you should have that data.) I would expect Firefox to simply "work" reasonably well, and as of the past couple of months or so, it hasn't.
W.T.F, Mozilla? I've used your browsers (Netscape) since the early 90s and have been quite happy - until recently, that is. As of now I'm having to go back to using Internet Explorer.
I sincerely hope Mozilla can finally resolve this issue as I still believe Firefox could be a great browser if it didn't "fight" with Flash all the time.

whatev, For issues using full-screen mode, turn off hardware acceleration in your [http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html Flash Player display settings]:
#Right-click on any Flash video or animation (or on the Flash logo on [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues this Adobe help page]).
#Click "Settings" and uncheck “Enable hardware acceleration" in the Display tab.
This isn't the best workaround since the setting may not hold, for example, if you clear all cookies in Firefox or with an extension such as BetterPrivacy. Updating your display driver would be the best solution,

Sites using flash/shockwave cause Firefox to hang.

If the shockwave flash plugin is enabled on version >22, visiting a site that contains flash content will cause Firefox to hang/react extremely slowly. I've tried disabling all add-ons with no effect.
I'm using shockwave flash 11.2.r202.310 but it doesn't seem to matter when version of flash I use.

Thanks for the replies guys.
ComputerWhiz: No firewall or AV installed on my laptop.
cor-el: Nothing works. It is the shockwave flash plugin + >=v23 that is the problem. I've tried safemode, I've completely deleted everything eg moving the .mozilla directory and started a virgin firefox with the same results.

Flash causes Firefox to slow down and even freeze (and on a gaming laptop, too). How to fix this?

Every time I use the Flash plug-in (for videos on YouTube or PutLocker or whatever), FireFox just slows down a lot and even freezes. It happens very often now and it's really annoying.
By the way, I am using a gaming laptop so I am not sure why I am having these problems. My Flash plug-in and firefox are updated to the latest versions, too.
My specs:
Windows 7 Home Premium
Intel i7-2670QM CPU @ 2.20GHZ (8 CPUs)
nVidia GTX 560m 3GB vRAM dedicated
16GB RAM

Okay, so I uninstalled and reinstalled it. That helped only for about ten minutes and it started doing it again.
I don't know what else to do. :S

Flash player freezes in Firefox

Flash player is causing Firefox to freeze for about 30 seconds whenever I access a website which uses flash.
I am using the latest version of Firefox (v19.0.2) and the latest version of Adobe Flash (v11.6.602.171). This same problem has existing for at least the last 5 versions released by Firefox and Adobe Flash Player. My OS is Win7 64-bit.
I am 100% certain that flash is the source of the Firefox freezing problem because I can cause the Firefox freezing to stop and start again by disabling and enabling the Adobe Flash plugin. In order for me to make Firefox usable, I always disable the Adobe Flash plugin.
I have read on the web that many other Firefox users in the Win7 environment have the same problem that Firefox freezes when Adobe Flash is installed and enabled. There are many reports that the freezing in Firefox can be solved by disabling protected mode in Adobe Flash.
Unfortunately, the method available for disabling protected mode will not work for myself or anyone else that works on computers issued and supported by my Fortune 500 company. The method of adding a line to the mms.cfg file requires users to have admin rights to editing files in the \windows\system32 directory structure. The company I work for has all computers without such admin privileges. Since there is no alternate for disabling protected mode, myself and all 4000 of my colleagues have no options for fixing this freezing problem.
Can you please solve this issue by either 1) working with Firefox so that the browser will no longer freeze when Adobe Flash player is installed, enabled, and protected mode is enabled, or 2) make protected mode a configurable feature that can be enabled or disabled by any user group in Windows Control Panel.
Thanks in advance for you consideration,
jlavie5555

Hi jlavie5555,
I'm sorry you're encountering these pauses. We work very closely with Mozilla and have been hard at work trying to solve all related protected mode issues since this security feature was released. We do have a few additional troubleshooting steps you might want to consider taking (in addition to disabling protected mode.) Please see this faq for details:
How do I troubleshoot Flash Player's protected mode for Firefox?
We also have a new 11.7 beta available that contains significant changes to improve protected mode. I suspect you might be blocked from installing it, but if this option is available to you I would recommend giving it a try.
3/7/2013 - Flash Player 11.7 Beta
Thanks,

You can check for problems caused by a recent Flash 11.3 update and possibly downgrade to Flash 11.2 or 10.3.
