Hi,

Im running into this bug since i did a fresh install of Windows to 8.1

Since im on windows 8.1 facebook wont play youtube videos in any timeline, it simply opens a new tab, directs me to youtube and starts playing there.. (realy annoying)

It starts to load but opens the video in a new tab instead of showing the video in the timeline itself.

- Im on firefox 26. - Ive debugged facebook, - Reset settings of firefox - Reinstalled Flash player 12 (even tested 11,7 & 11,9) - Ive tried IE + Chrome - Disabled / Enabled ActiveX in IE - Disabled / Enabled hardware acceleration in flash settings - Installed Realplayer - Installed Shockwave - Went thru various troubleshooters on the forums

I dont know what to do anymore.. any suggestions?

Thanks,

Vevo or any other official music videos are not playing in Firefox. After loading for 10 seconds, I am getting "An Error occurred" error. I don't have this problem with other videos. This problem occurred yesterday, although I didn't do any system changes or software updates during the day. In Internet Explorer 11 which using HTML5 Player by default, those videos are starting to play but only after 10 seconds load and not immediately like other videos. When forcing HTML5 Player in Firefox those videos are starting to play after 10 seconds load like in IE but HTML5 Player is very instable in Firefox. Software wise everything is up to date and I already reinstalled both Firefox and IE but the problem is still there. Even System Restore didn't help. Net research also didn't bring any solutions.

The issue seems to be with DRM. Although DRM videos play on other sites like on Amazon Prime Video. I've done everything I could find on the internet as to fix this issue like I've checked and unchcecked play DRM content in the settings and cleared cookies and cache and everything but nothing seems to be fixing the issue. Also, everytime I load Netflix I get a little yellow dialogue box saying installing components please try again. This happens everytime I load Netflix. Now when I click on any video it asks me to install SilverLight, I've installed it already but still it asks me to install it to play the video.

To many people, this might sound like a Joke when i say Firefox can't play any video on Yahoo News on any Windows 8 Laptop Touchcreen, but trust me, I have tried everything; re-downloading Java, Flash-player, Adobe...etc, I even called Microsoft Support and my Computer company but they all said this is Firefox drama they should be able to fix the issue. Please help. I have three Computers and all can't play any video on Yahoo News, (Youtube is playing great, no issues). Please help.

I've recently tried to switch over from Chrome to Firefox, but one thing that is preventing me from completing the switch is that Google Play Music will not play on Firefox 39.

I'm currently running Windows 10, but I've tested this with 8.1 as well. When trying to load music from a radio station, or playlist, it just times out and says Can't Reach Google Play.

This works fine in Chrome and IE 10, 11. What is even stranger, is I can play music from my library on Google Play Music which is also streamed since I have nothing downloaded.

I've tried every fix I could find across the Internet with no success. This is my last resort before I have to switch back to Chrome.

Please help me keep the freedom and look of Firefox!

The only video that will play is youtube. All others, Fox News, Townhall, Amazon [on product page, not Prime video], etc, do not play. I have done all that is available in the help section, none of it worked. Error "invalid mime type" From CBS OS - Windows XP SP3 Firefox ESR 52.9.0 (32-bit)

when I am opening FireFox...it is giving empty space and not loading predefined homepage...the same with new window/tab any website i am entering is not showing "https://" and not loading either...tried reinstalling and refresh firefox options but no luck...

the options button is not responding under menu section...history button worked normally and cleared history, coockies, cache etc.

please help with any suggestions immediately...it is frustrating!

Firefox 81, media control function has a bug. All the sites that I use work with it normally. Except VK. Controlling functions like pause, prev or next are working ok. But system media pad always shows title and cover only of the very first track has been played.

Firefox just upgraded itself today and on all online movies a not-very-faint double image appears. I checked IE and no problems were seen. I then installed Google Chrome and it too works just fine. I looked into reverting to the older version, but got a message I was not allowed to that. The extension that the troubleshooter recommended apparently only on Youtube videos.

Hi Firefox community,

I have the problem that the color reproduction of videos seems wrong in Firefox. I have done intense testing with different browsers and could improve color reproduction for IE and Chrome by adding the metadata to the mp4 videos:

matrix coefficients: BT.709, Transfer characteristics: BT.709 Color primaries: BT.709.

Unfortunately these changes do not affect the color reproduction in Firefox. I have compared the color reproduction on an class 1 monitor as well I work in a post production facility. Firefox always differs to the reference using Windows and Mac. On an iPad nevertheless the colors are reproduced correctly in Firefox. Do you have an idea what metadata could be added to videos so that color reproduction gets better on Windows and Mac with Firefox? I have added an example, left Chrome, right Firefox. Thank you in advance.

HTML5 Animations do not render properly on machines running Windows 10 (version 1803, OS Build 17134.254). The same animation on the same computer works fine in Chrome. It also works fine in Firefox on Windows 7 machines. Issue did not start until late Firefox update came out.

Hello,

It's been 3 days since I can no longer play any video since Firefox Developer Edition. I added absolutely nothing and it happened suddenly. When I play a video, I hear the sound but the video loads endlessly. Same with the default HTML reader in Firefox. I tried to go to preferences and uncheck the graphics acceleration, to refresh Firefox, to reinstall it but nothing works! Even in private browsing without any extension, it does not work! I tried from another browser but it works without problems.

Thanks for your help.

At first, the same night I decided to update--things were fine but after using the browser hours later a second time: some flash scripts would simply not respond and freeze the tab the content is on or like in my question, constantly stutter. The problem for flash videos only seem to occur when I scroll onto links or when moving up/down a page. I encountered similar problem with FF7--like that time, I installed/uninstalled the flash player and even resetted firefox but to no avail--the problem persisted. It is also present while in safe mode. P.s. such problem is seemingly not present in other browsers which brought me to ask this question for assistance.

This is a recent problem that I haven't had before and none of the answers I've seen have solved my problem. Whenever I try to watch a YouTube video, it buffers for a long time. Sometimes I never get past an ad because it will stop two or three seconds in and the only way I can get it going again is to refresh the page. I have to constantly refresh to hopefully get a five second ad or one that I can skip in order to get to the actual video and when I get there, it starts buffering and at that point it either plays after a minute or two or it doesn't play at all. It does the same thing in safe mode. The only time I'm able to watch videos without this problem is in a private window.

I have uninstalled Firefox two times and refreshed multiple times, but nothing seems to be working. Every other website I get on works fine, but videos don't fully load on any of them. Can some please help me, I've been trying to figure this out for hours and I really don't want to use another browser.

I've always been able to have several videos playing at once in separate tabs.

Since a few days ago, as soon as I start the 2nd video, the first video's audio continues but the video freezes. To get the video moving again I have to turn it off and back on. Then it will start moving again, but the other's video instantly stops.

I've been able to have multiple videos playing always, until now.
