Longer Flash videos cause Firefox to hang.

I let the video download completely and it will play, skipping a few frames on occasion for approx. 10 min before the video freezes. The audio continues but Firefox hangs and takes about 98% of my CPU according to Task Manager, making it nearly impossible to run anything else. It used to run pretty good. Maybe it's the upgrades? Short videos work okay mostly, but the longer ones die.

Thanks for the replies guys.

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.

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.

Good work jc! You are a good student:-) All Java add ons in IE are correct and FF also. Nice.
Now that we have all of that out of the way, we can Uninstall and Install FP
This is the Uninstaller that you will download and SAVE to your Desktop:
http://kb2.adobe.com/cps/141/tn_14157.html
This is the Installer FOR INTERNET EXPLORER, download and SAVE to your Desktop:
http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_ax.exe
This is the Installer FOR FIREFOX, download and SAVE to your Desktop:
http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player.exe
After those are on your Desktop, you will do the following:
Close ALL browsers
Disconnect from the Internet
Disable All Anti-Virus/Spyware and any Firewall other than Windows Firewall Also check to make sure no applications that use Flash are running, check the system tray.
RUN the Uninstaller Once. Then Reboot and RUN the Uninstaller again(to make sure old files are removed)
Then RUN the Installer for IE and Reboot ONCE
Then RUN the Installer for FF and Reboot ONCE
Re-enable your Anti-Virus/Spyware and Firewall
Re-Connect back to the Internet.
Then using IE first, go to the test site:http://www.adobe.com/products/flash/about
Then using FF do the same test.
Then post back the results or if there were any problems and/or any messages.

Having Adobe Flash Enabled caused Firefox to Hang, and then to "Not Respond".

I Have the Following:
Firefox 19.0
Adobe Flash 11.6.602.171
Windows 7 Home Premium 64 Bit SP1
After I first install a new version of Adobe Flash, everything works perfectly.
If I shut down my computer & start it up again maybe 10 minutes later, I will START having a problem.
I Click on my Firefox Icon.
Then I click on one of my bookmarks, like for Tucson Weather ( at www.weather.com ).
While Tucson Weather is "transferring data' or "waiting" or "connecting" the small blue indicator that spins to indicate that the computer is working to get the requested page loaded freezes & stops spinning.
Now, If I click any where on the page including the scroll bar, the page becomes dim & a very light color, white the cursor resembles an hour glass. This only lasts a minute or so.
If I click on the "X" to close the window, either nothing happens, or I get a message that Firefox is not responding, & do I want Windows to close the page. I have Windows close page.
Next I return to Firefox, disable Adobe Flash, & Firefox now works perfectly - Only Videos at You Tube are mostly not possible. I have had this problem since at least last September.

hello, maybe it's an issue with the protected mode in the flash plugin - you could try if [https://support.mozilla.org/en-US/kb/flash-113-crashes#w_solution-2-downgrade-to-flash-10-3 downgrading to flash 10.3] (which is still supported) or [http://forums.adobe.com/thread/1018071#TemporaryWorkaround disabling protected mode] makes a difference.

Fan speed and CPU temp viewing Flash video in Firefox vs. Safari ?

My MacBook (two months old) running the latest Safari version (3.1) seems to be working unbelievably hard when viewing a flash video. The temps seem to cycle between the high 60s and mid 70s, and the fan blows at max speed constantly. On the other hand, when viewing the same flash videos using Firefox (2.0.0.12), there is only a slight boost in temp (high 50s to low 60s) and the fan speed hardly increases at all.
Has anyone else noticed this?
Why would the flash player on one browser be so much more efficient than another (Safari seems to labor, while Firebox breezes along)?

Thanks!
Well I guess the code in the Safari browser just wasn't well written. This is true even of the later version of Safari. It does work much better in FireFox, with no crazy heat-up or fan action.
I've pretty much given up on Safari now on everything by my iPhone and iPt, and only because I have no other choice.

What is the proper way to fix the Flash Plug-in issue that causes Firefox to hang when playing Flash videos

This is annoying and causing me to set my default to Chrome. Firefox hangs when playing Flash. I have tirelessly tried everything I could. Uninstalling Flash via the Adobe download. Uninstalling FF and every single one of it's folders. I've done it all, multiple times....and continue to have the exact same problem, any Flash video hangs. Please help, I have read countless articles about others having this same problem, yet nobody offers a real solution.

Flash causes Firefox to hang and never recover

This has been happening since FF 13. OS is Win server 2008 R2.
Flash plugin is updated automatically. As soon as any page with flash is loaded, firefox hangs. No way to get it to respond no matter how long I wait. Have to manually end process.
Same behaviour continues in FF 14.
I keep plugin disabled, but it is enabled sometimes after updating, and FF again hangs when flash is encountered.
Very frustrating.

OK, setting protectedmode=0 has solved the issue!

I loaded 4.0 and now I cannot view any videos. Flash player causes Firefox to stop responding.

I am running XP. I recently loaded Firefox 4.0 on my system.
There were a lot of problems loading some web sites. Your help system suggested to disable all plugins. I did this and I don't have problems with web sites anymore but I cannot view any videos. I have tried reinstalling Adobe Flash but it just causes Firefox to stop responding.
Ideas?

'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''''' {web link}
While you are in safe mode;
Press the '''<Alt>''' or '''<F10>''' key to bring up the tool bar.
Followed by;
Windows; '''Tools > Options'''
Linux; '''Edit > Preferences'''
Mac; ''application name'' '''> Preferences'''
Then '''Advanced > General.'''
Look for and turn off '''Use Hardware Acceleration'''.
Poke around safe web sites and see if there is still a problem. Then restart

With many open tabs (80+) Firefox regularly (every 10sec) hangs for a few seconds because of session storing where the CPU is at 100%. Btw that is the reason why videos in Firefox are hanging every 10sec, too. Why is this operation so demanding?

When I'm using Firefox for a long time and I'm working with several open windows and many open tabs (80+), Firefox hangs/freezes every 10sec for 1-3sec. This is very annoying. The reason for this seems to be the session store operation, which gets executed every 10sec. In my experience (or rather on my computer) this isn't noticeable when I'm just working with around 40 open tabs.
This also seems to be the reason for hanging videos in firefox (although youtube is quite robust; others are not) because they stop every 10sec, too. For this time (the 1-3sec) the taskmanager tells me that firefox is using all the available cpu power. I'm really wondering why the session store operation has such an influence on Firefox' behaviour.
My computer is a Core 2 Duo E6600 with 3GB RAM and a decent hdd.

Just some additional info:
I just had the problem again, and it even occurred when I did not have any tab open! I did not even use Firefox, but just wanted to start to use it, but it did not respond. There was _nothing_ open, and when I checked the TaskManager, the memory consumption was up to 300 MB, and the CPU was again at 100%. After the CPU was down to 0% again, the memory slowly decreased as well. First, to ~260, then to ~200, now to ~170 MB. Maybe it will decrease even further...

How to download flash video with firefox only?

I leaned that I can download flash video clips using only firefox browser without using 3 rd party
software,so when a video starts playing I select tools- page info -media, then I should select the video
file and save it,I am looking for a file with swf extension in order to save it, but here is the snag as many video file names are so long that it is impossible to see the extension which is normally at the end of the name,what shall I do?

Try with Firefox Addons
*http://addons.mozilla.org/
Try with RealTime Player - move an arrow over the flash video, realtime player shows a download link

Flash Video causes PC to randomly freeze

Hi there,
I really hope someone can help me with this problem.
I have recently built a new PC and found that watching flash video on websites can cause the PC to totally freeze, which requires a hard re-boot.
This does not happen immeadiatley I am watching a flash video, however if a web page has a number of multiple flash video streams, the PC will tend to freeze within 30 minutes.
This has occured on a number of websites in Firefox, IE and Safari. Here's what I've tried so far:
-Used different browsers (IE8, Safari, Firefox)
-Disabled hardware acceleration
-Changed IDE cables to windows hard drive
-If download a stream, changed the target drive
-Increased virtual memory to: 2,046MB (Initial) 4,092MB (Max)
-Run regcure to chack for registry issues
-The system is stable at all other times, including playing high end video games that are stressing the CPU and Graphics Card.
System spec:
Gigabyte GA-890GPA-UD3H Motherboard, AMD Phenom II X6 1055T CPU, 8GB DDR3 RAM, NVIDIA GeForce GTX 470 1280MB Graphics Card, MS Windows XP Professional 32-bit SP3, Hanns.G HG281 22" Monitor at 1920x1200 via HDMI
I would really appreciate of anyone has got any ideas on this one.
Best regards,
Steve

Hi, A couple of years ago I had ZA with a Router (not wireless) and it didn't work well with my XP and had to finally switch from ZA to another AV. What you might try also is to try just using the Modem without the Router and see if that is helpful. It may be that the ZA is too much for the Wireless Router.
Testing as you say would be a good idea and also running a scan for any Virus.
With all of the browsers having those problems, something aside from addons may be happening.
Posting this article about the H.A. and Drivers, etc.
http://www.adobe.com/products/flashplayer/systemreqs/index.html
I don't think this has anything to do with the freezing, but some sites require 3rd party to be allowed.
http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html
If it's not a Virus or Router/ZA then perhaps the drivers.
Thanks,

Certain Flash videos cause instant BSOD.

When surfing every now and then a Flash video will cause an instant BSOD. I suspect this is related to hardware acceleration, but haven't found a common link as it's not directly related to resolution or window size. I'm on a PC that should have no problem handling several graphics intensive windows at once and I would really like to be able to use hardware acceleration to take advantage of the system as much as possible. Going to try disabling hardware acceleration for now, but any other tips would be appreciated.

This sounds like a Flash plugin problem, i.e. not really a Firefox problem. Out of curiosity, does this happen in Internet Explorer as well when playing similar videos?

Java apps causes Firefox to hang, Firefox's or Java's fault?

Recently I've had serious issues with websites using Java, all of them causes Firefox to promptly freeze and I have to restart the browser. I can't enter any site that uses Java with the Java Platform enabled. I have tried reinstalling Java and different versions, along with any suggestions I could find in Firefox's and Java's FAQs, but so far nothing has worked.

skunktrader wrote:Maybe it isn't hanging, there might just be a very long timeout waiting for an ipv6 response
At first I thought that couldn't be the problem because it is a long timeout, but then I thought about it and realized that I've seen TCP/IP timeouts that are very long when the receiving party never replies to any packets.
I immediately looked at my firewall and saw that I have
ip6tables -P INPUT DROP
in my firewall script at start-up. Since I don't use IPv6, I decided to effectively disable it a year or so ago. I removed this iptables rule and Java applets work again. Furthermore, if I let the applet just sit for about 5 minutes (literally), the applet will run. I guess I never let it sit for that long before, although it did feel like I gave it enough time. So the problem does appear to be an IPv6-related timeout. Good call.
I had this iptables rule above the rule that accepts all connections on the local interface, so it's possible that I simply need to accept all local interface packets (and only drop foreign IPv6 packets) to fix the problem.
I don't know why my interface needs to receive any IPv6 packets for the Java applet to work, but it does. I'll get a packet sniffer out later today and see if I can make better sense out of what is happening.
dschrute: Do have have anything similar in your IPv6 configuration? Possibly another iptables IPv6 rule? I wonder if your problem is also caused by IPv6 not responding.

SOLUTION: Flash Video Causing Blue Screen & Lockups

Symptoms: While playing a flash video, your screen locks up; goes black; you can hear audio in the background; and/or Blue Screen of Death. The Blue Screen indicates a fault in nv4_disp.dll.
================= SOLUTION =================
Newer versions of Nvidia Drivers are causing the problem. Disabling hardware acceleration in Flash only reduces the frequency of the lockups, but does not resolve the issue.
Use this version of the Nvidia driver (but no later): 266.58
Get it here: http://www.nvidia.com/Download/Find.aspx?lang=en-us
This is confirmed to resolve the problem.
Later Nvidia drivers added CUDA 4.0 (Unified Virtual Addressing (UVA) and GPUDirect™ v2.0) which is the root cause of the issue with "older" cards such as the 200 series and the 8 series.
If you have a somewhat older graphics card, there really is little need to update past version 266.58.
========================

Flash video causes my Mac mini to crash displaying blocks of stripes

As you can see from the picture below, flash video sometimes (often though) causes my Mac mini with Intel Graphics HD 3000 crashes while displaying blocks of stripes and repeating "tick" noise. I believe it just plays audio data in a buffer repeatedly at that moment.
It looks to me that it failed in decoding the video. Probably it can be due to mal-formated encoding, but after rebooting if I move the play position to the same spot, it plays there correctly. So, probably somehow when there is somewhat wrong encoded data filled in a buffer to decode but there is some non-allowed operation is processed. ( like divide-by-zero. I don't mean that this one is due to divide-by-zero. ) Can be somewhat related to DCT block....
Flash plugin installed on my Mac : The latest Flash plugins for Mac
Mac Mini with Intel HD graphics 3000. ( last year's model )
is this going to be fixed soon? Probably this is a bug which is already being traced?

I haven't seen this occur before. We're going to need some additional info from you. Please see this tech doc for some simple troubleshooting steps (in particular, try the HTML5 vs. Flash video tests and try disabling Flash Player's hardware acceleration). The doc also explains what information we'll need and how you can report the issue to us.
