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?

Some HTML5 videos won't play in my Firefox browser.

This vine for example (https://vine.co/v/b3v5h3Piwt7) only shows up as a static image. I can click the mute/audio button though, but it won't play. When I look at the webconsole when I load the page then 2 javascript warnings show up, the first one say that the Mediasource [long url here] can't be encoded and another one says loading of all candidate sources failed. loading media paused.

I'm using Firefox 21.0 and I tried to run Firefox in safe mode with disabled add-ons, and I also tried to reinstall it, but without success.

Thanks in advance.

I am running Windows 7 64 bit and Firefox is my browser. All of a sudden I can not play videos at places like Democracy Now and many other web sites (E.G. Malcolm Gladwell) but most of Youtube is okay - except sometimes. I thought this may have been due adGuard but disengaging it or starting FF clean with no ad ons has no effect.

I was just informed by Costco Concierge Services that the reason is that both FireFox and Google Chrome have decided to “no longer support” certain add ons or plug ins (what is the difference if any between these tech terms of art?) and therefore if I can not play a video I will have to use Internet Explorer. Discovering what videos I can or can not use is a hit an miss case by case basis.

So, first is this true? I can not imagine Firefox or Google Chrome making a change that would actually require its users of many years to bump their prime product and, instead, turn to its prime competitors. That seems like suicidal sabotage. We are just every day end-users and not software engineers and the explanations I find are absolutely incomprehensible technobabble.

In plain English what is the real problem? What is the fix? And has Firefox actually decided to make us dump Firefox and turn to its competitor just to watch certain videos? Has Democracy Now decided to continue using a video format that is no longer supported by FF?

The attached pic is just and example. DN uses jW player but I find this problem at other web sites too.

About a month and a half ago MP4 videos in Twitter 29 played fine. Then I updated to the latest version of Adobe Flash player on both my Win 8.1 and old XP computers. That is when I started getting "This browser does not support video playback" error when trying to play a mp4 video in Twitter. I ran Firefox in Safemode ... no change. I removed all addons ... no change. All Plugins are Ask to Activate or Always Activated. I uninstalled Firefox and Flash player and reinstalled .. no change. The videos work fine in MS IE II and Chrome 53.0.2785.116 m. H264 Codec is installed. YouTube videos play fine.

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.

Most videos will not play (like on Facebook page) I have researched ALL OVER and tried many suggestions. Firefox is up to date and so are my players such a Flash player. I go to the same video in Chrome and it plays. Is my only choice to DELETE Firefox and USE CHROME which is not my choice.

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.

Every web page with video / audio content begins to autoplay (at the vid's highest volume) approximately 5 seconds after opening the page. I could disable this in Safari and Chromium, but see no option to disable the 'Autoplay' feature in Firefox. Worse, there are no plug-ins or extensions available that will allow this to be done. If you have had success disabling this annoying 'feature' (it's not a 'bug,' right?), please advise how it was done so that I may rid myself of these annoying vids. Thanks in advance.

When I've been playing YouTube videos lately, I've noticed that a bunch of black boxes have been appearing over the player interface (The controls below the video) while the video is playing. Unfortunately, I can't provide a good screenshot, as the boxes come and go too quickly for me to get them. This issue still occurs if I restart Firefox in safe mode. I think it started happening with Firefox 37.

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!
