Flash Player crashing in Firefox

System is:
MacBook Pro
OS X 10.10.2 (14C1514)
Firefox 37.0.1
Flash Player 17.0.0.134
Any web site with flash video causes the beach ball spinner, firefox freezes, flash then crashes and firefox unfreezes. This has been happening through different versions of ff and fp. I have turned off hardware acceleration and flash protected mode - no change. When will this be fixed? As is, Flash Player is useless, I have disabled it.
Ron Halstead

ProtectedMode is a Windows-only feature, so that doesn't change anything. If it's happening in software mode, then it's not related to the GPU (Mac configs are pretty constrained, so that's not typically the deal anyway).
You might want to run Disk First Aid and repair both the filesystem and filesystem permissions (sometimes verify filesystem permissions will return clean, then repair will fix a bunch of issues).
https://support.apple.com/en-us/HT203176
Caveat: Sometimes corrupted software is an early indicator that your disk is going bad. It's wise to ensure that you have current working backups, especially if you have anything important on the machine. Checking the disk for problems is a relatively safe operation, but will also give the disk a workout. If it's on it's way out, you may not get a lot of additional warning.
At that point, go ahead and blow away all of Flash Player's data files by going to:
Control Panel > Flash Player > Advanced > Delete All
If you're *still* having problems, let's try a clean install:

Adobe Flash Player crashes on Firefox (NetSteam, Stratus)

Flash Player version: 11,8,800,97 (last)
OS: Windows 7
Browser: Mozilla Firefox 22.0 (last)
Problem: Adobe Flash Player crashes on Firefox, when runnig project with such elements like NetSteam, Stratus.
When problem happen: Only when some streamed data is incoming, after random time. Time before crash can be 4 minutes, it also can be 2 minutes. Memory leaks or disk space usage didn't change and don't seem to be a reason. Problem happen when I was testing my voice chat together with few people. At one moment it crashed at few computers at the same time (which were using Firefox). Then we had luck with repeating this problem several times - simply by asking one of us to play any music into Microphone. Then Firefox Flash Player always crashing.
Here you can see repeating of problem: http://youtu.be/BdkoQxloyDA
It also show that it does not crashes if nobody is sending audio stream in created group, but it does when somebody is sending audio stream. In that video I'm repeating problem by myself, with help of one computer and 2 tabs of Flash Player. First is running in Chrome, second in Firefox. Player in Chrome is used to send system sound from speakers to peer group. Player in Firefox is listening and playing everything he hears (this is why I set it's volume to near 1).
Here is .swf :

It's very simplified voice chat which only displays streams which are being heared. It's adding " is talking" when stream is sending data. "g" parameter is a group name, I think you can choose any, but tests were made with this one.
Hope it helps. If you will need .fla file - just tell me.

Your issue is distinct from the original poster's issue about a crash on Mac. I've branched this out to a new thread so that we're not confusing everyone.
Firefox on Win8 isn't very stable. We're collaborating with Mozilla on improvements, and my test results with the daily development builds are really promising, but it will be a few more weeks before they actually make it to production releases.
In the meantime, you're way better off using IE or Chrome.

Trying to find out which line of AS2 code is causing flash player crash in firefox & chrome browser

Hello,
I have a flash movie (AS2) created for the website visitors' registration and this flash movie is longer in size than the browser's window height so that site visitors need to browse down using browser's vertical scroll bar to see all of the contents in the flash movie.
When users click the submit button in the flash movie then
Firstly, the AS2 code attached to the      on(release){    event scrolls the html page back to the top (because the user must have scrolled down to view the flash movie content at the bottom of the page and I want the html page to go back to the top of the page)
getURL("javascript:window.scroll(0,0)");    // this is the AS2 code I have used for scrolling the page back to the top. I suspect this code is causing the flash player crash in firefox and google chrome
and also tells the _root of the flash movie to go to and stop at a frame named "StartEnteringData".
_root.gotoAndStop("StartEnteringData")     //making the _root of the movie to go to the "StartEnteringData" frame
this.gotoAndStop("Start")                                  //making this movieclip which contains the registation form to go to the first blank frame labelled "Start"
The "StartEnteringData" frame on the _root of the flash movie has AS2 code for entering the registration data to the database by using loadVariablesNum( ... )
Here's my question.
Almost everytime the user/visitor click the Submit button, the firefox browser users and google chrome browswer users see the Flash Player CRASH...
This doesn't happen often with the website visitors using MS Internet Explorer.
I have read some www articles (by searching google) saying that Adobe Flash Player in Firefox and Chrome browsers crash a lot.
But, for my flash movie, everytime the visitor clicks the submit button, flash player crashes. Therefore, I guess it is the AS2 code that I'm using (associated with the on(release) event of the submit button) is causing the flash player crash rather then the flash player compatibility with Firefox and Chrome browsers.
So, someone please tell me what's causing the flash player crash.
Is there a better code to make a web page to go back to the top?
I am also using the codes shown below on the first keyframe of the main movie. (_root)
//For custom flash right click menu:
var myMenu_cm:ContextMenu = new ContextMenu();
myMenu_cm.builtInItems.zoom = true;
myMenu_cm.builtInItems.quality = false;
myMenu_cm.builtInItems.print = false;
myMenu_cm.builtInItems.save = false;
myMenu_cm.builtInItems.loop = false;
myMenu_cm.builtInItems.rewind = false;
myMenu_cm.builtInItems.play = false;
myMenu_cm.builtInItems.forward_back = false;
_root.menu = myMenu_cm;
//For tiling the flash movie background with bitmap picture
import flash.display.BitmapData;
var tile:BitmapData = BitmapData.loadBitmap("pattern");
this.beginBitmapFill(tile);
this.lineTo(Stage.width, 0);
this.lineTo(Stage.width, Stage.height);
this.lineTo(0, Stage.height);
this.lineTo(0, 0);
this.endFill();

by repeatedly commenting out lines of code you suspect are causing the crush and retesting you should be able to pinpoint the problem.

Flash Player crashes on Firefox and Windows 8

I too have this problem and it occurred after Firefox's recent update.
The Flash Player crashes any time I open a website with embedded Flash videos.
I cannot watch anything that requires Flash Player and when on Facebook, the pages continually crash. I send a crash report each time then reload and it crashes again. I send about 20 reports per hour and am sick of it and have started using another browser where I do not have this problem but my preferred browser is Firefox.
I have Firefox 35.0.1 which is the latest version.
My operating system is Windows 8
The plugin I have for Flash Player is Firefox, Mozilla - NPAPI 16.0.0.296 however when I check with Flash Player, it tells me the version I have is 16.0.0.235.
When I try to upgrade, I am informed that my version is up to date.
Steps taken
- updated Flash Player
- Cleared caches
- Unchecked hardware acceleration in Firefox.
I cannot find the menu for Flash Player as I'd like to try to disable hardware accelerator there too.
HELP please.

Flash player crashes in firefox but not in waterfox ??

You can check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
*disable hardware acceleration in the Flash plugin

Flash Player crashes in Firefox immediately

The Message goes as follows:
Adobe Flash Player 11.6 r602 has stopped working
A problem has caused the program to stop working correctly. Please close the program.
This message appears over and over until the page is closed. Also, sometimes the "plugin container" crashes too.
Attempts at Fixing It:
I've tried disabling the plugins.
I've tried disabling the hardware acceleration thing.
I've tried updating adobe to the latest version.

Re: How to roll back to a previous version
From the link I provided:
Step 1: Uninstall Flash
To uninstall Flash on Windows, you will need to use the uninstaller provided by Adobe.
Download the uninstaller program from Adobe - uninstall_flash_player.exe (676 KB)
At the top of the Firefox window, click on the Firefox button and then select Exit
Run the uninstall Flash program that you download and follow the prompts.
When you are finished, start Firefox again and continue with the next section.
See the Adobe help article Uninstalling Flash Player on Windows for more details.
Step 2: Install Flash 10.3
The following instructions will show you how to download and install Flash 10.3.
Download Flash 10.3 from the Adobe site - install_flash_player_10_plugin.exe (3 MB)
At the top of the Firefox window, click on the Firefox button and then select Exit
Open your downloads folder and double-click the file named install_flash_player_10_plugin.exe to start the installation.
Follow the instructions in the installer. When the installation is complete you can open Firefox again.

Flash Player crashes IE9, Firefox and Chrome

The latest version of Flash Player 11.4.402.287 is causing my browsers (IE9, Firefox and Chrome) to crash when I'm on Pixorial. I've contacted Pixorial customer service but they say it's a Flash Player problem.
I'm running the following:
Windows 7 Professional
Chrome 22.2.1229.94 m
IE9 9.0.8112.16421IC
I have updated the display adapter driver (I read somewhere that might help) but no change. I am having the same problem on my laptop at home which is using the exact same versions I have typed above, except it uses Windows XP.
Any help is sincerely appreciated. I'm at the end of my rope and I don't know how to fix this.

I got reply and they said it's not necessarily a Flash Player problem. The app need to load heavy resource to run so it might be causing performance issue under your HW/SW configration. Have your machine with same setting worked fine before and suddenly started the issue after installing Flash 11.4.402.287?

Flash player crashing w/ Firefox

hi everyone,
I have been having an annoying issue where flash player is crashing only when I use Firefox. no problem with Chrome on the same system.
Can you point me in the right direction?
Thanks in advance for you assistance.

I have had the same problem for some time. Not only with Firefox, but with Internet Explorer (7 and 8) and Google Chrome. I am running a Windows 7 Home edition (version 6.1 build 7600) 64 bit O/S, and have read through multiple forums where the web browser is being criticised (unfairly?), and have tried all solutions offered there and here. I have uninstalled and re-installed the adobe flash/shockwave flash at least a dozen times, I have disabled all add-ons to try to isolate if this was a problem, and the flash player wouldnt work at all, but as soon as I enabled the Adobe Actve X the problem began again, so it is not another add-on causing the issue. I have disabled the hardware acceleration. Still a problem.
I am running version 10,1,102,64 of Adobe Flash Player
Firefox version 3.6.12
Internet Explorer version 8.0.7600.16385
Google Chrome version 7.0.517.41
I use Windows updater so I am assuming that all Service packs, drivers etc are up to date.
I use Avast Antivirus
Any help to solve this ongoing very frustrating problem would be much appreciated. It used to be that after un-installing and re-installing Flash it worked for a few weeks before constantly crashing, this last time it is crashing immediately, hence I am posting here.

Flash player Crashing in Firefox 6 Beta

the Adobe Flash player is regularly crashing in Firefox 6 beta I have the latest version updated, so whats the problem?

Yeah, I've been having this issue too. It wouldn't be such a bother if all it was was a simple refresh away, but with that god damn poorly coded plugin container in tow it causes my computer to drag it's feet so bad that it nearly crashes the whole damn thing. I'll give them a little time to fix it, but Chrome is looking nicer and nicer all the time.

Flash Player Crashing on Firefox and IE9

I recently updated my firefox and Flash player to the latest versions and now everytime i want to watch a video or anything that is used with the flash player, the flash player keeps crashing and tells me that i need to update it.. I have already tried uninstalling it and installing it again and it still won't work I don't know if its because i have a bug or what is the prob exactly. It was working on my IE9 before i uninstalled and installed again the latest version, but not on firefox. Now its not working on either. I have the Acer Aspire 5100 32-bit running on Vista Home Premium. If anyone can help, I would SO MUCH appreciate it.

what i did following his instructions, was using firefox, go to http://www.adobe.com/software/flash/about/ like he mentioned above and your going to see the adobe flash player animation on top of the page. Right click on the animation and click on "settings" and then uncheck the "enable hardware accelaration".. It still won't work on my IE since i have IE9 and its still beta. But it shouls work if you follow the instructions using firefox

Flash Player Crashing Safari/Firefox

Over the last week Flash Player has rendered Safari and Firefox virtually useless... whenever I load up a site that uses it I get the pinwheel of death and if I look in activity monitor it always has a reference to Flash Player plugins not responding.
Chrome seems to be fine somehow, but it's a total resource hog so I hate using it.
By the look of this board and twitter it sounds like I'm not the only one... any help here?
I'm using a 2011 MacBook Pro and OS 10.10.3

Hi,
Could you please provide more information like browser version, flash version and the site you are trying to open
Thanks

Keith Gilabert, "Flash Player Crashes on Mozilla"

Flash Player crashes on Firefox when I have more than two browsers open. The browser that are being operated simultaneously are Internet Explorer, Firefox, and Chrome. For some season the Mozilla browser crashes when playing video.
Please advise.
Thank you,
Keith Gilabert

Hi, You may want to go to this site: http://www.adobe.com/software/flash/about/. Right click on the Flash logo, Settings,
then UNcheck the hardware acceleration in Display Settings.
Then make sure that in IE you have the Security Setting for the Internet Zone set to Medium.
Hope that helps,

With the latest Firefox, I keep getting error messages on Tumblr, and Flash Player crashes almost every time I watch a video on Tumblr.

This has been driving me mad for days now. I updated to the latest version of Firefox, but every single time I go to any webpage on Tumblr, (my dashboard, my personal blog, anyone else's blog) I am bombarded by error messages saying "too much recursion." I usually get anywhere from 3 to 5 messages per page. I reverted to Firefox 34 and can now access Tumblr just fine, but then I am faced with a different problem. When watching videos or vines on Tumblr, they can spontaneously lag, jitter, or stop playing. If I try to resume playing them, then they might start playing but all audio will be cut out. This seems to cause some kind of problem with Flash Player, because after it happens on Tumblr, then it will happen on ANY video playing site I visit. If I try to watch a video on Youtube, the video will spasm for a couple seconds and then go to static and say "An error has occurred, please try again later." I've tested it out on other video sites like Blip, and they also cause audio and video bugs. Even if I close Firefox and restart it, the issue will not be solved. The only way I have found to fixing the crashes is to manually reinstall Flash Player (which requires me to reset Firefox anyway). This has been a tremendous annoyance, as I have had to reinstall Flash Player and reset Firefox about five times on any given day for the past week or so. This is driving me to consider dumping Firefox for Chrome, and I don't want to do that.

Okay, I updated my graphics card drivers just for good measure. I also started Firefox in Safe Mode, and there weren't any bugs. So I isolated the problem by turning on my extensions one by one, and it turns out that something with my XKit extension was the cause. I manually removed XKit and reinstalled it directly from the XKit website. Now everything's working fine again when I use Firefox 35. Thank you!

Since the last Firefox update, flash player crashes when I start my cam

When I start my webcam in a chat room, Adobe Flash Player crashes. If I do not start my cam, everything is fine. I have the latest versions of Firefox and Flash Player. I have windows 98
== This happened ==
Every time Firefox opened
== I installed the most recent update

I have the same problem as well, however, I have noticed that the issues seem to be local to specific sites.
In my case, its tinychat.com, and tokbox.com. I have no problems getting into Tinychat, but when I try to cam up or even access the settings in regards to the camera dialog, adobe crashes.
So far, I can chat and cam anywhere else I please with no issues that Ive found.
Another thing i noticed, is it worked fine the first time i logged into Tinychat, but on the next subsequent visit, it was broken and remained so after.
