Ondersteuningsforum voor Firefox

I am using Firefox 35.0.1 and I have installed Shockwave Flash 16.0.0.296. As soon as Flash starts, Firefox freezes and unfreezes until it can't be used at all. I have tried uninstalling and reinstalling the flash player and I have also used Firefox's Refresh option. This problem started a couple of days ago & I don't know what else I can do.

So, interesting opportunity to learn something new! ;) What is wrong: buffering. At first I thought I have problems with Flash alone, but this isn't true. Any video [be it on Youtube or Twitch, Flash player or HTML5 player, doesn't matter] randomly will stop. I will see the buffer "icon" and... nothing happens. Ever. I can leave it for as long as I want, it will not budge. On Twitch.tv it's a bit different, it will pause the stream for a solid minute and then "restart" itself.

Cleared cache, session files, updated Flash, used Ccleaner as well. Don't want to go through creating a new profile yet (a bit of a hassle), trying to figure out what might be causing the issue. As I said, it's very random, sometimes happens in short video on Youtube, sometimes I can watch long videos without much problem. And no, my internet is not the issue, double checked on that.

Any ideas?

Hello everyone

I think that recently I had to update Flash version and it was all okay even after the update. But yesterday videos on YouTube all of a sudden stopped displaying. Just like that, in the morning they were okay and then around of noon, all of sudden blank. Didn't install anything new or something.. now I only get White screen with no any border, just an empty spot where the video should be. Beside that, any other flash content [i.e. videos on Facebook, vimeo are not displaying as well]. All I get on YouTube is constant "loading" indicator beside the cursor which keeps blipping.

Now the strange thing is first - I have no problems with this on other browsers like i.e. Google Chrome, and second.. IF I uninstall Flash from my PC, I can watch YouTube videos on Mozilla although the max resolution is 720p.. and vimeo/facebook videos will still not work. How da heck is that even possible? O.o

I've tried a lot of different things and nothing helped.. here are some of the them [I hope I won't forget something]

- Uninstalling Mozilla/Flash then installing them again - Uninstalling Flash, then letting Mozilla suggest me to add it - Disabling/Deleting all of my extensions - Turning off that hardware acceleration thingy - Deleting cookies from YouTube then adding them to exceptions - Clearing out whole history/cache or whatever - Right clicking on the "empty space" where video should be.. to see if any options will pop-up [Of course they don't, there is no video to start with] - Scanning for viruses [Nothing]

Can anyone please help me? Any suggestion, what can I do?

Happened a few days ago, every time I play a flash video on my Firefox only! chrome and explorer works fine , the image freezes I need to start clicking around and all my icons turn black and it returns to normal and then freezes again, what the hell? this is my favorite browser and I don't want to move to chrome, so please help :(

Hi I am in the same situation as many others I have seen posting here. Shockwave flash is continually crashing to the extent it takes several minutes to get to the add-ons manager and disable shockwave flash. I have reinstalled all adobe plugins, so they are up to date. I am having real problems accessing a lot of web pages/web page content because with shockwave flash enabled firefox is all but frozen and with shockwave flash disabled a lot of web content isn't available.

I have looked at other threads that I found and have attempted all of the suggested solutions and have selected the Troubleshooting Information option below this text box. I have a huge list of crash reports, unfortunately I am not sure how to load them

Any suggestions appreciated

Regards.

Videos will start along with sound but the video will stop although sound continues.If I move my pointer over the video it will jump to where the progress bar indicates where the video is at it's current playback time.How can I fix this problem?

hey guys, i wasnt sure where i could put this info, i have discovered some info regarding the "FLASH PLAYER PLUGIN." that doesnt seem to be documented on any kb article or support thread, so hopefully one of you will be able to help getting this submitted. obviously this wont fix everyone's problem, but it should be included.

THE PROBLEM::

Flash Player Hanging or Crashing (unable to watch flash/video content) Script has become unresponsive error message when trying to view flash/video content

THE SOLUTION:

a possible cause to this problem is that you have lost permissions to the file directory where flash is actually stored. without these permissions you will be unable to properly utilize the flash plugin on firefox.

to fix the problem we will need to update the security settings on the flash directory.

for 32 bit machines: C:\Windows\system32\Macromed\Flash

for 64 bit machines: C:\Windows\SysWOW64\Macromed\Flash

navigate to the \Macromed\ folder and right click on the flash folder and select properties. click on the security tab at the top of this box then on the advanced button at the bottom of this box. after navigating to this screen, you will need to click change permissions. first make sure there is no deny statement which is denying access to this folder, if one exists, remove it. second make sure that the name "Everyone" has the abilty to read and execute, to do this: click on everyone, then edit. next, select: apply any changes to: "This folder, subfolders, and files." this is at the top of the edit box. after you click ok to the changes you made, you will need to enable the option: "Replace all child object permissions with inheritable permissions from this object." now click the apply button, then ok button. now check to see if firefox is working.

if you find that you are unable to change these permissions, then you lost access to the parent folders as well and they are replacing child object permissions. you will need to apply the solution above to the parent folder that is overriding the permissions. this will either be: \system32\ or \SysWOW64\ depending on your machine or possibly even the \Windows\ folder.

If you find that these parent folders indeed had their permissions lost, then you have likely acquired some malware. You should download Malwarebytes Anti-Malware and do an update and full scan.

I just started getting this black screen instead of some youtube videos whilst they are running , and whilst the sound still goes on perfectly fine. It's rare that it happens and it can change into the normal image, and when i change from full screen view to normal view it can also change back to the normal/real image. Does anyone know what that could be from?

For the past few days Firefox browser videos requiring Flash player do not open but give me the 'crash screen'. It works fine with Internet Explorer because it is built in. I have tried all of the recommended fixes from adobe and and firefox.

I have refreshed Firefox
I have enabled in firefox
I have disabled all plugins and extensions then tried enabling Flash Player
I have uninstalled and reinstalled Flash player a few times
I have tried adjusting Flash player settings
    " deleting FPs cache, etc.

I have not been able to adjust FPs "hardware acceleration" because it won't open in the support pages.

I have: a newer toshiba Satellite L70 (intel i7)

64bit

windows 8.1

I am stumped!

System: Intel I5-2500 @ 3.30GHz 16GB RAM Win 7 Ultimate 64bit OS which is run in Admin Mode FF33.0 32bit ran in 64bit (Large Address Aware 2.0.4) TuneUp Utilities 2014 x64 Perfect Disk 13 (all drives are done in Smartplacement Performance)

Network: Telenet Fibernet XL (189.85Mbps down, 9.45Mbps up, 9 sec latency)

Services: None

Now, whatever I do, such as typing, every 5 seconds I get a 2'ish second freeze. Often, I crash loading a new tab. I run appx. 24 tabs. Tune Up Utilities has Simultaneous Connections for FF on Unlimited.

Minor Questions: Why does my system, which is not too bad, does this? It should be able to run FF smoothly, no hangs, no crashes. But it does not seem to work this way. Do I have conflicting Extensions, or Plugins? Do I have conflicting Extensions that run amok with a plugin? Why do some Plugins appear double? Can I kill one of the doubles off?

Major question: How can I make FF smooth again?

Thank you beforehand: Xog

I can go into chrome without any issues and watch any video without any problem. the second i get into firefox nothing works. i have had this issue on and off for years. i really do not see why you cannot fix this if everybody else can. i have uninstalled and reinstalled firefox and flash player multiple times. nothing seems to work. I am truly getting really tired of this same problem year after year, i stay with firefox because you are privacy conscience and are being more so consistently. i do not know what other details to tell you other than this just keeps happening and it is making it very tough to do anything on firefox when i cannot use a simple thing such as flash player. as i said, if the other browsers can fix this i see no reason why firefox cannot year after year. i hope there is a simple fix for this problem because it has basically halted a lot of my work on the net as i will no longer use google or microsoft. thank you

Hello all, So Just yesterday I noticed that when playing videos on youtube in full screen, i get a lot of sound crackling and video slow down and the likes. Also happens in other sites such as shush.se

At first it seemed to happen after Flash updated but my laptop updated the same and there is no problem there. It happens both with the flash and the HTML5 player, FF only, on chrome there is no problem.

If i enable hardware acceleration in the flash player settings, then there is no video at all, just a green screen.

I'm using win7 64-bit (actually just re-installed windows-not related,but i had 32bit before, hoped it would help but didn't)

Please help!

Hi Everyone,

I see that problems with MP4 playback are fairly common but I couldn't find a solution to my problem in any of the several questions and answers I've reviewed.

When I comment out the OGG code at http://www.deiryassin.org/video.html I cannot get the MP4 file to play. The OGG file play back in Firefox is just fine. Someone else who uses the latest version of Safari for the Mac OS was not able to get reliable MP4 playback, either. Per w3schools.com, MP4 is a supported fiie type in both Safari and Firefox.

I don't know how to embed HTML in this question so please see the attached PNG file for the code I used for testing MP4 playback. The MP4 file location is correct and the file is not corrupted, it plays fine when I download it.

When I try to play it in Firefox the browser console/error log says: "Specified 'type' attribute of 'video/mp4' is not supported. Load of media resource /media/deiryassinremembered.mp4 failed." The browser displays: "No video with supported format and MIME type found".

Here are the codecs for the file: Codec: H264 - MPEG-4 AVC (part 10) (avc1) Codec: MPEG AAC Audio (mp4a)

The following lines are in my .htaccess:

AddType video/mp4 mp4 m4v AddType audio/mp4 m4a

I've re-enabled the OGG source for visitors to the site. Any ideas on what I'm doing wrong?

Thanks.

A year ago, I had a video freezing problem. disabling hardware accelorator appeared to work, but doesn't work now for same exact problem. tried other solutions that were suggested a yer ago. Nothing work. It appeared that the video problem fixed itself. This is very fustrating that this is happening again and makes me believe that firefox never solved the initial problem after a year

I have the latest version of flash player installed and enabled. When I go to Adobe's test page, it recognizes the install and lists the correct version number, but the test animation at the top of the page fails to load properly. Also, the applications handler in Firefox's 'options' menu fails to list any flash compatible file types. On YouTube, I'm met with the video throbber stuck, unmoving, against a black rectangle. Right clicking the video and trying to view the 'settings' dialog does nothing.

I have tried deleting 'pluginreg.dat' and a number of other solutions I've found online, but nothing has made a difference. My other plugins (java, acrobat, etc.) all work fine. Thanks, in advance, for any help.

I will watch a video on YouTube (any video) and the PICTURE will pause a second while the audio continues uninterrupted (no matter the quality I put it on). It happens every 20-50 seconds (even while not in full screen). I have adobe flash player installed.

Hello,

Since the latest FF and Flash update (37 and 17) I can't watch any videos or flash content - like (annoying ad) banners. Everything literally FLASHES. Like a strobe light. Then videos get stuck, the cursor jumps/freezes, sound stutters and eventually mac crashes (panic). The fans are constantly hyperventilating but nothing weird is running in activity monitor.

I have:

• Uninstalled and reinstalled flash; same for Firefox; cleaned flash cache - nothing
• I only have flash, java and QuickTime plugins installed
• Downgraded flash to previous version (16) - better, no flashes, but still stutters and crashes after watching video for 10-15 minutes most (sometimes not even that)
• Tried to watch using VPN but after a while graphics and sound go crazy
• Decided to upgrade again to flash 17. Now it flashes again and I can't watch videos for even 1 minute.
• Tried the about:config media.mediasource.enabled (change to true); dom.ipc.plugins.flash.disable-protected-mode (change to false); Firefox "get info" open with 32-bit mode; - nothing worked

What can I do? Any idea? Thanks

For many MONTHS now......I have been having this problem......and from what I can tell now (after I have just installed an older VIDEO DRIVER).....the problem is DEFINITELY (or at least I'm VERY sure) to do with the ADOBE FLASH PLAYER

I have Windows 8.1.... Adobe Version is completely up to date: Version 17.0.0.188 i am using FIREFOX (also up to date): Version (ok, the "help" part of the menu is NOT opening to confirm the version...but it IS up to date, as I get updates automatically).

Here is the PROBLEM: EVERYDAY that I go online, sometimes INSTANTLY....or it may take a little time before it happens......but using Firefox, my "Browsing"....or video watching becomes slower and slower and slower. To the point that in some cases.....it will take up to 5 MINUTES just to switch screens when I click on one of the "Tabs" (when I only have 2 web pages open).

    Pages seem to take FOREVER to load, etc.......and there is a huge "lag" from when I CLICK on something......to when the computer actually does what it's supposed to do........and the at the WORST.....the pages, videos, etc......will just "CRASH"

• • • • I always submit the "CRASH REPORT" per the Adobe Banner.....but nothing ever happens of course from that (it's just useless probably)

Now.....the reason I KNOW the problem is "ADOBE FLASH PLAYER".......is because I have some "TV" running in a tiny window in the background (which also suffers the same problems as above). And it, too, will crash, etc.

What I HAVE figure out.......but only as a TEMPORARY and SLIGHT "fix"......is that every few minutes........I need to open up my "TASK MANAGER"........and actually "END TASK" on the ADOBE FLASH PLAYER.

 When I do this.......and give the computer a few seconds to catch up...........the computer speed is GREAT!!!!!       But, once Adobe Flash gets going again.....all my problems start again (and the cycle starts over again and again)

• • • • • the WEIRD part about the "Task Manager"......is that ADOBE FLASH PLAYER is barely using ANY of my computer's "memory" (RAM I presume????).....as is Firefox.

My computer has a total of 6 (SIX) Gigabytes of RAM........and when I look at the Task manager.........ADOBE FLASH PLAYER is using up MAYBE 100 mb of that. And the most I've EVER seen Firefox using is around 800 mb

So......unless there is a major issue with Firefox working with Adobe...........(or Windows 8.1 completely screwing up.....which wouldn't surprise me either).........ADOBE FLASH has some SERIOUS issues :(

Is there ANYONE OUT THERE.......that knows anything about this.......or HOW I can fix this?????......so that I can actually enjoy "full speed" web browsing again ALL DAY without having to worry about "maintenance" all day long???

Thank you in advance for any help you can provide!!! And please....if you have ANY QUESTIONS>......or need further information from me....please let me know. I am fairly good with computers (but not super "techy" if you know what I mean).....but I should be able to find what you might need if you ask me to look for something :)

Many regards, Scott Simpson
