Hello folks, I've been a long time user of Mozilla Firefox but for whatever reasons lately I cannot for the life of me get gifs or vines for that matter to play on Twitter or Tweetdeck. The gifs are always a blank space with the pause button only being seen. Vines, some do play when they have the little bar at the bottom of it but others do not motion at all.
Now if I use Google Chrome, everything is perfect. The Gifs and the Vines.
I've searched the forums here and followed all the procedures that were given with none working at all for me. Edit the about:config and then restart, still nothing. Refreshed the cache with CTRL + F5 but still no changes. I tried the Web Console Network tab but I just got overly confused so I have decided to come to these forums, sign up finally and hopefully find a solution.
Many thanks in advance. Any more info needed, I'll give.

I have noticed that when I stream video on both Vimeo.com and YouTube as well as other sites, the framerate is greatly reduced compared to when I stream video using Safari. I know it's not a hardware issue with my computer. Is there some problem with a plugin in Firefox. I enjoy Firefox because it's the fastest browser I have, I like the design, and it's very easy to customize. But I use Safari more often because of the video stream is very choppy. How could I possibly resolve this issue?

While on facebook, if I watch one or 4(Random number) videos using facebooks own player, not youtube, or scroll down my frontpage wich usually have a large number of videos, firefox connection to the net seem to be lost. When this happends, whatever webpage I try to access in Firefox just gets a "Loading" status in the tabs bar.
Only fix so far is to close and relaunch Firefox.
When doing that, I also find that XMark Sync has lost connection and can't sync up.
While this happends, I have tried IE, Chrome and several chat softwares, like Skype, and these function as supposed to. So the issue is somewhere in Firefox.
The reason I point towards Facebook videos(html5?) doing something to Firefox, is that so far this has only happened while on Facebook, and while watching, stopping, switching to HD, skipping forward/back or scrolling past videos on the frontpage(These autostart when they are "front").
This happends at random, but alot, so much I have pretty much stopped scrolling the front page or looked at videos posted on facebook.
I am stumped.

I receive an error msg saying 'Deze browser ondersteunt het afspelen van video's niet.' Meaning the browser doesn't support playing video's. This is the only video that doesn't play, however.
IE and Chrome show no problem.
Switching off add-ons didn't help.

Hi I have a problem with my new bought hp pavillion 10-k000ng with windows 8 1. The camera is working just fine outside firefox, but using it for firefox hello is not working. No error message is shown, it only goes to a black image. I also do not get the media symbol beside the url field. I also tried other webpages for testing the webcam and on non it is working. Therefor, I think it must be a problem of firefox and not hello. Thank you very much for your help! cheers Evchen

I installed the unity web player plugin ages ago, to play online games, but since earlier today, Firefox becomes unresponsive (or occasionally, Unity crashes) when trying to play those games. I never had this problem before. I have restarted my computer, I have tried opening firefox in safe mode, I have done a virus scan, and I've tried reinstalled both firefox and unity, and my problem still persists. I have no idea what I can do to fix the problem.

When making videos full screen (from all sites I've tried so far, but specifically YouTube, Vimeo and some of the news outlets), the video gets choppy, like it's using a much slower framerate.
I've tried this on all resolutions from 4K on down to 240 with the same results.
Flash works fine. The videos play just fine in the Echo browser. The videos play just fine in the small in window player, in Firefox.
I'm using FF 43.0.4. I've tried it in safe mode with the same results.
This is on a Dell XPS15, Windows 10 (1511), 16GB RAM, Intel 4600 and NVIDIA GeForce GT 750M video adapters. Hardware acceleration is disabled.
Again, Flash goes full screen just fine. HTML5 does not. What do I need to do to be able to enjoy full screen videos in HTML5?

First off I'm using Firefox 44 currently and I've used a copy on my work PC that has well used user profile and also a fresh install on my home laptop without any additional addons with the same result.
I'm struggling to make html5 videos work across all browsers. I thought I had this nailed until I realised it had stopped working in Firefox. I'm currently using the following code to load video via a html5 webpage (I know this is html talk but please bear with me as I believe it more likely be a bug with firefox than my code):
EDIT: ok so it won't show my html 5 code properly and I can't find any instructions on how I should put html5 code into the questions on this support forum, so here it is in [tags], just replace the  with <>
<!-- first try HTML5 playback: if serving as XML, expand `controls` to `controls="controls"` and autoplay likewise --> <!-- warning: playback does not work on iOS3 if you include the poster attribute! fixed in iOS4.0 --> <video width="900" height="506" poster="videos/poster.jpg" onclick="this.play()" preload="none" controls> <source src="videos/playme.webmhd.webm" type="video/webm" /><!-- Chrome10+, Ffx4+, Opera10.6+ --> <source src="videos/playme.mp4" type="video/mp4" /><!-- Safari / iOS, IE9 --> <source src="videos/playme.oggtheora.ogv" type="video/ogg" /><!-- Firefox3.6+ / Opera 10.5+ --> <!-- fallback to Flash: --> <object width="900" height="506" type="application/x-shockwave-flash" data="videos/player.swf"> <!-- Firefox uses the `data` attribute above, IE/Safari uses the param below --> <param name="movie" value="videos/player.swf" /> <param name="allowFullScreen" value="true" /> <param name="allowScriptAccess" value="sameDomain" /> <param name="flashvars" value='autostart=true&controlbar=over&file=https://www.examplesite.com/videos/playme.mp4' /> <!-- fallback image --> <img src="videos/No_Playback.jpg" width="900" height="506" alt="Oops No Playback" title="Your browser cannot play this file, please use another browser" /> </object> </video>
The page has several videos listed all with the same result. I don't believe its the code causing any issue either as even if I load the webm video directly in the url it still will not play. I've loaded the webm video in chrome without problem.
I can see from the network tab of the web console that it is trying to load the webm file and that the MIME type is correct, but it just displays the poster for the video and the correct length of the video. If I hit play it won't play, similarly if I try to seek it won't either. I've tried it with multiple videos too.
I did initially convert the videos from mp4 h264 into a webm using the webmhd preset in miro video converter. However I've also used the following command using ffmpeg to reconvert the video as suggested elsewhere online:
ffmpeg -i input.webm -codec copy -avoid_negative_ts 1 output.webm
As it is suggested that it could be a bug with negative timestamps in some version of firefox, but this still fails to load anything but the first video frame.
I've attached a screenshot of what I can see. The poster is a yellow jpg which states press play, so what you're actually seeing is the first frame of the webm video after I've hit play (as preload has been set to none).
I'm assuming it doesn't use the mp4 as a fallback because the webm should be working? I don't want to have to put the mp4 first as its larger in file size and not an open standard that will be permanently adopted. Plus the mp4s seem to take an age to load on android mobiles.
Now this code works fine in all other browsers, as does the webm files as stated above, except for either Firefox or Firefox Mobile on Android (can't test it on Mac as not an apple owner). I've tied it on various PCs and laptops (windows 7 & 10), and also my Sony xperia Z3. Currently using my windows 10 hp omen to type this.

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.
