Firefox closes on websites with Flash content

I have been experiencing this problem after the last couple of updates. I'm currently running 3.6.6. On nearly every site that runs Adobe Flash content, the content loads to the point that I know it will work, but Firefox stops loading the content, freezes, and then closes with no error messages. I reopen it and it asks for a session restore, but only about half of the time. The other half, it restores the tabs to about 10 seconds before the crash. I would open Speedtest.net, for example, it would load the player to when the blue line appears in the bottom, and then the loading wheel in the tab would freeze. After that, it closes. It has happened every time I opened that website. It would happen on other site with flash games as well.
I have reinstalled Adobe Flash by uninstalling and then reinstalling. I have also manually upgraded Firefox again. None of these have fixed the problem.

Open up computer case, unplug and take out the processor fan cooler and wipe out all the dust, speccially in the heatsink, with a soft little brush and compressed air spray (also check power supply fan). I discovered this solution after weeks of trying all software related recommended steps and nothing worked, adobe flash player was still crashing in firefox, chrome and opera even after completely uninstalling flash and installing latest version 10.2.152.26 of the plugin. I realized this was the problem when pc started to crash unexepectedly when not playing flash videos. So, EUREKA, that did the trick for me. Hope it does for you.

Websites with flash content are causing tremendous CPU usage!!

Greetings!
I finally installed the long-awaited version 4 of firefox, and I am really disappointed. In addition to slight sluggishness now and again, it turns out that websites with Flash content (even those sites with a little flash advertising banner) are causing my CPU usage to really go up.
It's slowing down my machine, making my CPU fans spin loudly, and making for a disappointing web browsing experience.
I have disabled all add-ons, and done the usual. Even tried installing Chrome for the first time ever!
The problem is definitely Flash + Firefox 4.
I have created a brand new profile, but no dice. Wondering if anyone else experiences a high CPU load on pages with flash...

Adobe Flash Player has also been crashing periodically on 2 of my computers, I'm still running XP, one of them a powerful HTPC, Dell Optiplex 755 SFF over a new Cable Internet Connection. Buffering, Lagging, crashing when streaming video for Catchup TV (Freeview) via Firefox Adobe Flash Player Add-On, does not happen on Youtube though. Lagging & Crashing does NOT occur AT ALL in Google Chrome, but I hate that browser.
Have tried the usual disabling Flash Hardware Acceleration + Protected Mode, setting storage to Unlimited, disabling FF Ad Blockers + Hardware Acceleration, cleaning Caches, updating program versions, everything bar reinstalling programs. It's not happening in Chrome, why in Firefox?

Opening Safari websites with Flash content

Opening websites with flash content
How do I open these types of websites on my IPod Touch Software version 3.0?
This is a huge oversight if it cannot be done and a Flash Player App is not available for download.
Thanks for any response. Derrell Brown

This is a huge oversight if it cannot be done
Flash is a proprietary technology owned and controlled by Adobe. It's nothing to do with Apple. Flash is also slow, buggy and RAM hungry. You can't really expect a technology that even runs poorly on relatively high-specced computers to run that well on a low-powered handheld device.
Web-sites are generally moving away from proprietary technologies like Flash in favour of open-source technologies such as Javascript, AJAX and HTML5 - all of which work on the iPod touch, and can reproduce many of the Flash-type effects you see on Flash web-sites.
Over time, I'm sure Flash will be used less and less as more and more people access the web 'on-the-go' from handheld devices, and open-standards become the norm.

Firefox crashes on pages with Flash content

MacOS 10.6.5 on a 2008 MacBook Pro
Firefox 3.6.13
See below for Flash Player version info
Well I just updated to a new version of Firefox (3.6.13) and I had Flash Player 10.1 installed. Every time I open any web site with Flash content, Firefox crashes. This happens with Yahoo Mail, CNN, New York Times, etc. So I disabled Flash temporarily, and my Yahoo Mail no longer crashed. Of course I can't watch any online videos now....
I tried uninstalling Flash Player 10.1 using the Adobe uninstaller, and then re-installing it. No go. I tried the beta 10.2... still crashed. Finally I found a version of Flash 9 for Mac on Adobe's web site, and that does indeed work. Of course it's an older version, but at least I can use Firefox. The bad news is that the plugin is used by Safari also.
Any ideas?

I tried something else for now, since I'm using Flash Player 9 on my main system hard drive at the moment....
I have a bootable 48GB SSD in my ExpressCard slot. I often use it since it's faster. It has the same configuration of Firefox 3.6.13 and FlashPlayer 10.1, but it seems to have no problems. I right clicked a Flash animation and the hardware acceleration in on. Now why would it work on my SSD drive, but not my main hard drive?

Firefox crashes/closes on websites with flash

This started yesterday when I was prompted to download and install the 3.6.7 update for Firefox. After restarting the browser, I get a message that it was not installed correctly, and then it closes without warning. It does not give the usual message that there is a problem and Firefox needs to close.
After experimenting, I've noticed that this only seems to happen when trying to load websites that include Flash content. Gmail and Youtube cause it to crash immediately. Other websites, like Facebook and certain forums will load initially, but will crash on certain pages, where there is probably a flash video or other application.
I tried starting Firefox in Safe Mode, but I still get these crashes. When I go to about:crashes, I get no reports of the recent crashes.
I still can't update Firefox to latest version, so I still have 3.6.6. Every time I try, the installation fails. I do have the latest version of Flash.
I believe I've tried everything suggested in the Knowledgebase, so if anyone has any suggestions I would really appreciate it.

Firefox 7 consistantly crashes with flash content

This is quite frustrating. Ever since the release of FF6 the performance of Firefox with Flash related content literally sucks! The plugin container is ALWAYS crashing consistently.
It seems that in Mozilla race to compete with Google Chrome in their rapid releases has resulted in rapid blunders. If better testing was in place this crap would not be happening. Mozilla needs to slow their roll in all honesty of people that have been long time Firefox users are going to move to Google Chrome since it is not plagued with issues that are getting all kinds of loyal Firefox fans pissed off over something so simple as flash.
I have had more problems with crashing since Firefox 5 has come out. Obviously the proper testing has not been done by Mozilla. In the 3. series i maybe crashed once a year, now is daily! WAKE UP MOZILLA!
Before I go any further i have read numerous post in here with people have the same problem. I have also done some testing on my own from what Mozilla suggests, in which NONE of their solutions corrects this issue. My solution however, which is not a solution but more a work a round solves totally any plugin-container.exe crashing. It was simply to roll back to Firefox 4.01. I updated to the newest flash player via their site.
I have been crash free for days now! THIS IS NOT AN ADOBE FLASH ISSUE. If it were then i would have crashed in 4.01 as well. For those concerned with the update nag, simply go to options->advanced-> and the tick boxes. that will prevent the nag
I thought that i could re-install Firefox 7 and simply replace the plugin-container.exe from 4.01, however that did not work. It resulted in a complete lock up of Firefox 7.01, and was honestly hoping that it would be that straight forward.
I read some peoples success with the 8b3. So, I tried that, and didn't solve my problem. I crashed within 24 hours again on flash related content. ( the crash ids are for the 8b3 i listed ).
Maybe someone needs to take the plugin container, and associated components in 4.01 and incorporate it in a new release, or revert back to that engine all together so that we can have a nice web experience without all the crashes.
You can get Firefox 4.01 here:
ftp://ftp.mozilla.org/pub/firefox/releases/4.0.1/
edit: replaced random unofficial download site link.

I have found the bug thread, and have posted several posts with information and some examples of sites that provide positive crashes.
https://bugzilla.mozilla.org/show_bug.cgi?id=561019
From reading the posts, it looks as if Mozilla has moved this up a bit in priority according to reading into a post from one of the mozilla's team members since I have provided information concerning the crashes.
That particular bug ( Bug 561019 - Plugin waveOutOpen hangs ) is the TOP crasher of plugins:
https://crash-stats.mozilla.com/topcrasher/byversion/Firefox/7.0.1/7/plugin
As far as reporting bug/hangs. The end user has to press the " submit crash report " link to submit it. If they do not it will sit there until you go into about:crashes
For hangs that DO NOT produce a crash you once again have to go into about:crashes and click on all the reports that DO NOT have a " bp " in front of them to get them to actually submit. They will post in about 3 minutes.
So for the "400 million" said users and " hard facts tend to suggest that most users do not crash " is unreliable to state since it is TOTALLY up to the end user to submit the report providing they know how. I know from working in a professional environment 99.9% of users do not submit error reports of any kind when something crashes the OS or any program. Even with the 9 members of my team they always click "do not send" except for myself.
" Get rid of plugin container " is a non option since you run the risk of features not working as i have found when you do that.
It does seem like a Firefox issue for several reasons: latest version of flash with Firefox v4.01 works flawlessly, and Chrome and IE do not have this issue with flash.

Autorun CD-ROM with flash content on website

I have two websites with Flash content that I need to put on
a CD-ROM for a presentation on a computer with spotty internet.
I've created the autorun part fine, but here's my issue. When the
html page pulls up in a browser and the link to the Flash content
is clicked, I get a security warning that " Adobe Flash Player has
stopped a potentially unsafe operation." Everything is on the CD -
nothing should be trying to access the internet - and I'm looking
for a way to override this security warning without having to
rebuild the flash files. So far, most of the info I've found deals
with changing something on the user's computer, but is there a fix
that can reside on the CD (so the user doesn't have to do anything,
or ever see the warning?)
Thanks!

The basics of what you are asking is pretty easy to do in
Director. To
make a menu, just import your graphics including buttons.
Create a
frame label on the timeline for each video. On each button,
add the
behaviour named 'Jump to Marker Button' (it is in the Library
under
Behaviours, Controls). Pick the appropriate label for each
button in
the resulting popup. Then import your video and place one on
each
frame. Put the 'Go Loop' behaviour on each of these frames
(in the
frame channel). That behaviour is in the Library under
Behaviours,
Navigation.
Depending upon how your movies are setup, the rest will be
different
(i.e. are the Quicktime, avi, wmv, RealVideo, etc?). But the
Library
has behaviours for a lot of them, and building custom scripts
is pretty
easy as well if you can put forth the effort to learn Lingo.
It is
actually among the easiest to learn languages in my opinion.

Win8.1/Chrome 64bit: NPAPI Flash Player crashes on every page with Flash content

Hi,
Chrome 64bit (beta+) crashes on Win8.1 64bit, if I use the NPAPI Flash Player (v15 beta or v14 stable) and open a website with Flash content.
More details here:
https://code.google.com/p/chromium/issues/detail?id=402262

Turning off NPAPI in Chrome 64-bit will be a very bad move. I'm using a Windows 7 Setup, with a Core2Quad 65 nm CPU and a pathetic Geforce GT 8500 GPU that is basically worthless. PPAPI flash betas are available as a standalone now at this point, but I have done lots of side by side comparisons, and the PPAPI plugin is absolute garbage compared to the far superior Netscape architecture based plugin. I'm not the only one saying that. I have found loads of forums, and instruction videos online to fix Chrome video playback on youtube for instance. I have to install "Magic Actions for Youtube" addon for chrome so that I can disable HTML5. then I have to go into the plugins menu on chrome and disable pepper flash. I keep the 64 bit flash betas regularly updated this way, and I am getting peak performance. Once in a blue moon it will crash, but I think that is Google's fault. HTML5 should not be the default option in youtube. Compared to Flash, it does not have great GPU acceleration ability, and HTML5 in 64-bit doesn't even perform superior to 32 bit web browsers, where as 64 bit flash is a leap forward, as long as it's the NPAPI version, that is. Problems I have with the HTML5 and also Pepperflash are very similar. The audio is out of sync with video, and the cpu is maxed out from memory leaking. I'm skipping frames and seeing glitches left and right. The seek functions in pepperflash never work right on youtube, you have to click an inch before wherever you want the video to play. On and on. Pepper flash has audio crackle. You can't get rid of the crackle from pepper flash or HTML 5. Yet, with NPAPI 64 bit flash beta in 64 bit chrome canary it plays PERFECTLY. once in a while I have it crash, which i think is the fault of the fact that I have to use an add on to force off HTML5. Why would I want html5, when flash NPAPI 64 bit produces superior picture quality on all quality settings. It's better in every conceivable way. Shame on Google for not putting more care into 64-bit flash on 64-bit Chrome. It couldn't possibly be a more important deal! You can tell pepperflash and HTML 5.0 are an afterthought. It's only youtube playback quality. why would that matter to google? OMG...
While I'm at it, I have one other issue that blows my mind. Adding command line flags in Chrome 64-bit (Canary) in Windows. Why do we have to add them through a shortcut in the "target" line? The target line runs out of space after 3 or 4 commands! I wish they would update Chrome Canary to allow for unlimited command lines to be added. It should be an option to add Command Lines on the About:Flags screen. I am so disappointed in these two glaring issues. It keeps me up at night.

Firefox hangs on all sites with flash content.

Firefox hangs on all sites with flash content. If I disable the flash plugin there is no hanging but obviously no flash content either. I have tried all the suggested actions found in the help sections for hanging and plugin problems. The Honda UK site listed below is one of many I am unable to access with flash enabled.

Yep, the most Windows 7 32-bit machines wont fail.
What about hardware, are there similarities here? Attached devices/drivers? Software that is running at the time?
These machines are all from DELL. They all have normal hardware, nothing special. Other machines from same type does not affected. Software: All have standard software distributed via Software-distribution (GPO). Only some PCs have special software, but it is not running. No special drives, too.
Maybe try booting Windows in safe mode to see if it still hangs?
Good idea, indeed - I will try this.
We're definitely interested in what's going on. I'll ask our security and Mozilla folks to see if they have additional clues.
Thanks!
EDIT:
Safe mode: Flash is working! (without disabled Protected Mode!)
I've set msconfig now to: Custom system start and deselected the boxes to load systemservices and system start elements.
So, now windows does a non-safe mode boot but no service or element was loaded except the drivers (right?). Flash is not working with this config!
So, whats the difference between safe mode and normal boot with minimal configuration (see attached picture).
Only drivers will be loaded, right? If so, I can exclude the network and graphics driver as source: graphics driver are updated right now and network was working in safe-mode.
Any new ideas?

My 14.1 firefox , websites with flash contain or videos don't work & youtube give me a message "an error occurred please try again later"?

'''Hi,

Can you open up your Real Player and tell me what version you have? I think Real Player 15.0.6 is supposed to fix this problem. There was a conflict between Real Player and Flash this whole summer that broke Flash videos. Real Player released a update that might help in your case.
If that doesn't help, I think a addon might be to blame here. So do this:
<br> '''Firefox button <img src=https://support.mozilla.org/media/uploads/images/2012-03-27-09-22-48-1204f1.png> > Help > Troubleshooting Information'''
<br> (or '''Tools > Help > Troubleshooting Information''')
Then click the "Copy all to clipboard" button then paste it here. It will tell us what addons you have installed and I can see which one might be causing problems.

[FP 11.4 & FF 14.0.1] Firefox hang on every page with flash-content

Hi at all
I have a problem with the new Flash Player, let me explain it:
We have a windows-domain with software distribution via GPO.
Since update to 11.4 via the msi package (11.3 was previously installed) we have in the meanwhile 3 PCs (all Win7 x32 with FF 14.0.1 and Flash 11.4) with this problem:
- While loading a page with Flash content, the Firefox simply freezes and have to be killed together with plugin-container in order to work again.
If this happens, ff and plugin-container have 0% cpu-usage. It freezes and does nothing...
If I remove Flash: Web-pages are working, but without flash.
What I've tried:
reinstall using flash-uninstaller
Using "normal" end-user web-installer
Uninstall via Uninstaller and tried 11.3 again
reinstall Firefox, both 14 and 13
Nothing helped to bring Flash-support back.
This happens only on FF, Internet Explorer is working fine...
Can someone give me a hint?

High CPU usage on sites with flash content

I have a 2.8GHz, 2GB RAM, Windows XP Pro SP2 machine.
When I visit sites with alot of flash content with Firefox 3
or IE or Chrome my CPU goes to 80-90% and stays there.
I uninstalled flash player and reinstalled the latest
version, but with no fix to the problem. Don't seem to have any
virus/spyware on my system.
Uninstalling Flash player on each of the different browsers
seems to fix the problem - visiting the same sites, I don't get
huge CPU usage.
Any ideas what underlying thing might be causing excessive
CPU usage in all my browsers when visiting flash sites?

To make clarifications for my previous post (some people emailed me saying that the link says nothing about cpu hogging or excessive cpu usage), you may not visit the LINK previously provided and instead follow the steps given below.
I would also like to point out my kind of problem that these steps successfully solved. The problem was this:
The first time I start up a browser (IE, FF, Opera, or Chrome) and visits a website with flash player files running on it, the performance of my
computer is smooth and fast for the first 2 or 3 minutes. But afterwards, the CPU usage meter just suddenly shoots up from below 10% to a shocking
100%! And there was not other program opened, except the browser; and I was only visiting one website ( e.g., Youtube).
It then clearly indicates that flash player is the culprit, since I have already run windows updating, spyware and antivirus scanning, defragmenting,
browser cookies and cache clearing, junk cleaning, and drive checking. I have also tried uninstalling and reinstalling flash players, which was actually
a good thing except that during that time I have not yet known about the next 4 steps (given below).
If you have the same problem, you might try th following:
NOTE: Close your browsers and any other running programs and opened windows first.
STEP 1: Navigate your way to this folder: Computer > C: Drive > Windows > System32 > Macromed > Flash
STEP 2: Right-click over the file ‘Flash10a.ocx’ and choose ‘PROPERTIES’.
STEP 3: In PROPERTIES, choose the ’SECURITY’ tab > Click on the ‘EVERYONE’ account or your own Windows account profile, and the button called 'EDIT’ and then tick the box called ‘ALLOW FULL CONTROL’ and also choose your own Windows local account name to have full control.
STEP 4: Repeat this process for the file ‘FlashUtil10a’.
Open a browser and check the performance of your CPU.
PS:
The example here indicates that the flash player version is 10; however, you can still use the steps for lower versions. For instance,
if the version of your flash player is 9, look for all files named FlashUtil9a (disregard the extensions).
Also, the Folder Directory is applicable for Vista users. The file directory structure of your drive C:\ may be different if you are using other windows OS version. You just have to search the location of your Flashplayer.
To:
montian and franky --- i'm so glad this procedure helps you with your prob!

Can't interact with any open windows, can't interact with flash content

I've already tried reinstalling, resetting and deleting my profile, nothing's changed.
I can't close any Firefox window by pressing "x", or by pressing Alt+F4, I can only close it through the task manager or task bar. Minimising or going into windowed mode is also impossible.
If a new window opens itself (e.g. A download) I can't interact with it at all - It's visible on top of the main window, but nothing I do affects it.
I also can't interact with flash content (like pausing a youtube video)
There is absolutely no feedback when I try. The icon doesn't change.
I recently reset firefox, there are no add-ons, themes etc. installed, the problem persists.
I am running Windows 7 64bit, everything else (including other browsers) appears to be working fine and a virus scan (Avast! free version) turned up nothing.
I'd really appreciate any help!

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

If the Flash object has focus then key presses are processed by that plugin.
In such cases you need to click outside that plugin (e.g. the menu bar if you can't click on the website) to make the keyboard work.
