Firefox frequently hangs when loading websites with Flash video.

Firefox frequently completely freezes when viewing Flash video and the only way to release it is to manually kill the plugin-container process.
This have been verified with several Firefox versions, upto and including 3.6.10 and upto the lastest Flash release on systems running Windows 7 64-bit. This have been tested on multiple installations, different systems and on clean installations. However only tested on 64-bit HP systems so far.
Running Firefox with "Run as Administrator" enabled or with compatibility mode set to "Windows XP SP2" seems to solve the problem, but that solution is not good considering the security and performance problems following with that.

I have done some more testing and the problem seems to have been found:
Windows 7 64-bit with Firefox and Flash works fine until HP ProtectTools Security Manager Suite is installed. That combination makes Flash video playback hang frequently. Uninstallation of HP ProtectTools Security Manager Suite fixes the problem.
Flash video playback works fine with Windows 7 64-bit and HP ProtectTools Security Manager Suite using the browsers Internet Explorer and Chrome instead of Firefox.
At the moment I can not tell if the error is with Firefox, Flash or HP Protect Tools.
I am using the latest versions of Firefox, Flash and HP ProtectTools Security Manager Suite at the time of writing, including latest Windows security patches.
HP ProtectTools Security Manager Suite installation file name used for this is sp48447.exe.

  • Hangs when loading websites at times

    this happens only in firefox if it is taking too long to load website, which happens quite often on desktop and laptop, I have to stop the load, then restart and it always comes up immediately. Explorer doesn't do that, but I don't want to switch back unless I have to.

  • My firefox 7 frequently hangs when loading 4 tabs or more.This happens as with the old firefox 6. Trying google chrome brings me a flawless operation even for how many tabs and how much flash embedded videos it have.

    Frequently hangs

    I'm still looking for a more complete answer. "Upgrading to Firefox 8" doesn't tell me what the actual problem is, nor does it guarantee that the problem will be resolved (certainly not from what I've read online).
    But thanks for responding. I appreciate the time.

  • Ios 3.1.3 fails when browsing website with flash, doesn't skip flash, hangs

    Im just looking for someone else that might have had this issue, to maybe point me to reason or a solution.
    I know that the iphone doesn't support flash, and would expect when viewing a website, that it just bypass the flash (skipping it, or just displaying a box with "needs flash to view"), but we are finding that version 3.1.3 is locking up, when we goto www.gostanford.com with ANY IOS other than 3.1.3, the device loads the webpage, simply just doesn't display the flash and continues to render the remainder of the site. However, with 3.1.3, the whole screen goes white, and a real small "Click here to download the latest flash plugin to view content..." displays and moves no further. It just stops there, I've tested on our 2g and 3g devices with ver 2, 3.0, 3.1, 3.1.1, 3.1.2 and they all display the page minus the flash content. IOS 4.0, 4.1 on my 3gs and 4 phone due to same thing, its just version 3.1.3 that does this.
    I want to tell the customer, sorry, we dont support iphone, but the rest of the company is expecting at least a reason why this is happening? Has anyone here had or experienced any issues with the 3.1.3 that I can draw from, or point me to a location.
    Thanks in advance.

    The link you specified works perfectly with my IE6 and
    Firefox 2.0. The purpose of the javascript script is to provide a
    cross browser sloution to deploy flash animation in HTML. As IE
    uses object tag and doesn't support embed tag and other browsers
    vise versa this kind of mechanism is essential. And that javascript
    also allows you to check the installed flash version. I see no
    problem of your page.

  • When loading websites with a lot of thumbnails that are linked for example to imageshack Firefox 6 will just freeze and become unresponsive. If i press the reset page buttom sometimes they will load or sometimes firefox will crash, why is this?

    If a website has a lot of thumbnails or animated gifs for example firefox will become unresponsive and sometimes either lag and use a lot of system resources i have seen it as high as 1.2GB or it will just lock up and crash.

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.
    *https://support.mozilla.com/kb/Safe+Mode
    *https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
    In Firefox 4 and later [http://kb.mozillazine.org/Safe_mode Safe mode] disables extensions and disables hardware acceleration.
    *Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
    If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

  • Firefox runs very slowly when it opens website with flash videos like youtube or dailymotion

  • Firefox often crashes when I watch a Flash video

    If my memory serves me right, it doesn't necessarily need a video to crash.
    I tried Safe Mode and memtest86+, Safe Mode crashed anyway and memtest found nothing wrong. Also, I tried updating Flash to the latest version, without any improvement.
    == Crash ID(s) ==
    b493b847-abd1-4093-9917-932d82100607

    Hello J.
    Yes, Flash tends to do that sometimes, for some users. Thankfully Firefox 3.6.4 (the next update for Firefox 3.6) will not crash when a plugin crashes, which is very good!
    Meanwhile, you may want to make sure all your add-ons (plugins, extensions, themes and all) are up to date. To manage add-ons go into ''Tools > Add-ons''. It's fairly straightforward. If they are, or if updating them doesn't fix it, you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
    Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
    If you want support for one of your add-ons, you'll need to contact its author.

  • Errors on Website with Flash Video

    Me again. I finally got my video into the webpage, and I can
    preview it with F12 and it works fine, but once I open other
    websites, it downloads, but with errors. I tired Internet Explorer
    and Mozilla. I have tried the link checker and and stuff but I
    don't see any problems. How do I find out what is wrong with this
    page on the internet?

    The truth of the matter is that if you do not know anything

    your experience with DW will be a stumble from one mysterious

  • 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, this issue only happens on Windows 7 32-bit machines, currently 6.
    Do you have any 32bit systems that don't fail?
    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?

    ''Duplicate post, continue here - [https://support.mozilla.org/en-US/questions/934607]''

    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.

    Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See:

    Create a new profile as a test to check if your current profile is causing the problems.<br />

    There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"<br />
    If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

  • Websites with Flash Not Loading

    My browser is IE7, after installing Macromedia Flash Player I
    am still unable to view websites with flash, I have checked add ons
    in the browser settings and it shows that flash is enabled, in
    addition I use McAfee Security Suite.
    Any assistance as to solutions or settings I can try,/change
    would be appreciated.
    Regards
    Simon Ward

    You're welcome.
    I'll be backing up to a 1TB ext. drive, so I'm going to set up Time Machine and maintain regular backups.
    Time Machine is great for recovering specific files/folders. I find a clone backup much more effective for going back to a previous HD state. I think both are essential. The latter is created with SuperDuper or CarbonCopyCloner.
    I have Time Machine and a bootable backup on a 750 MB HD. One partition matches the size of my iMac HD (297 mb); the rest if for Time Machine. Works well together. I create a bootable clone every few weeks or so, or just prior to a significant update to the OS, such as an incremental update, eg 10.5.6 to 10.5.7, or any Apple update requiring a "restart". This way, if something goes awry I simply can start-up from the clone and copy it back in a few minutes to the HD (only those files that have changed in the update are copied).

  • 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?
