Hello guys! I'm having some periodic crashes when i listen to youtube music in background. It happenes randomly, maybe once a week or sometimes twice a day.

I tried removing some unnecessary plugins but it didn't help.

Here are my logs in pending folder (or is there any way i can upload them in some readable form?)

When I try to see the video on this site, I get a message saying that something went wrong. On the same page, a dialogue window is available to choose quality for external player: automatic, high, very high. I can choose high or very high and then i can see the video.

For the arte.tv/fr website there is no such a choice available and so I cannot see the video, message is: video file cannot be played.

For youtube videos FF is ok. I would be very gratefulif you could help me as I tried a lot but to resolve the poblem , without success!

Video makes fans run obnoxiously compared to Safari

Using firefox to watch video such as amazon prime content causes the fans on my macbook to run obnoxiously compared to Safari for some reason. I don't get it. Why? Same video in both browsers using the same plugin causes very different results.

I use XRG app to watch the temps and stuff like fan speed.

Safari running the videos uses a good amount of CPU (~70% - 90%) and CPU die temp of 71C, where Firefox will run the CPU clear up to the 150%+ range and a die temp of 85+C. The second I stop the video, I see the case temps (sensor1,2,3) start to drop pretty quickly. Is there a different version of Silverlight for firefox that is different from Safari's? I'm stuck with Silverlight for the Amazon Prime stuff.

Pretty much, video in Firefox sends the case temps to somewhere around 39-42C, nothing crazy, but with the die temps, enough to kick the fans up to the 3500-4000 rpm range watching the videos.

Safari on the other had shows case temps around 30-32C and fans that sit steady at 1999- 2048 rpm watching the videos.

h.264 videos that played in Firefox 34 won't play in Firefox 35.0

We host a ton of h.264 videos in the mp4 container displayed through JW Player. We had zero problems with Firefox 34 and earlier playing these videos, the video is H.264 and the audio is AAC, the whole thing is around 500 kbit/s.

They play fine on Firefox 34, Chrome and IE but after updating to Firefox 35.0 we get an error: "Error loading media: File could not be played".

We have found a fix to get them to work in the about:config, switching "media.fragmented-mp4.enabled" to false OR switching "media.fragmented-mp4.exposed" to false will allow our videos to play. Single file mp4's will also begin to download where before we would get a "Video can't be played because the file is corrupt."

Alternatively for Mac users if they just set media.apple.mp4.enabled to False it also works fine.

Non h.264 mp4 videos will play fine.

Here is a playlist that won't play: http://media.vineyardinstitute.org/other/vi_announcement/firefox-test.html Here is the single video file: http://media.vineyardinstitute.org/other/vi_announcement/05_kingdom_theology.mp4

Is there anything I can change on either the playlist or the video files to get this to work? Why would the h.264 files that worked in Firefox 34 NOT work in 35? I will not be able to re-encode all of the videos, it would take me months. Is this a bug with Firefox?

Also I have tried this in safe mode, tried with every plugin deactivated, I have uninstalled Flash and the videos would not play as well as reinstalling a new version of Flash and a fresh copy of Firefox 35.0

Any help would be much appreciated, we are currently directing all of our users away from Firefox till we get this resolved.

Thanks,

Kyle

I'm going to my movie website and recently been getting this message. I would click on the movie and it would look like it would start playing and then get this message. Is it Firefox or the website which is hosting the movies?

Is there a workaround to this?

I'm using a Mac with the current OS.

I do have a PC running Windows 7 also

Thank you

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.

Recently when trying to watch facebook videos I've encountered this issue where I'm watching the video and 1 of 3 things happens. 1. The video suddenly stops but the audio continues and this continues regardless if I move forward or backwards in the video. This sometimes continues to happen if I refresh the video or restart firefox.

2. Im watching the video and suddenly audio from a further part in the video plays over the current audio, so not only does the audio not match the video, but its audio from further in the video.

3. Sometimes I click another part of the video and the image freezes but the audio continues . Just like issue 1.

This didn't happen before. I recently had a virus, plus a windows update that really slowed the computer down so I removed the virus and system restored to remove the updates. These issues continued happening and after a clean install of mozilla it sill does this.

How to stop videos from loading on metered connection?

I'm currently using nightly and, while videos with audio are muted by media.autoplay.ask-permission, and further they are paused if you also set allow-muted to false, the problem is that they still load.

On a metered [or slow] connection, this is a big problem.

Viewing a news article on ABC [for example] pre-loads the entire video in the background.

To make matters worse; Even after the entire video has been cached, a steady stream of 200KB/s is still continually streamed from the CDN.

Example link: https://abcnews.go.com/US/noreaster-season-east-coast/story?id=58738494

If you monitor bandwidth with Firefox's network monitor, or a 3rd party tool [like jnettop for Linux], you'll see that the page continues to load video data.

Not only would I expect it to not load any if playback is disabled, but it certainly shouldn't continue to load data, perpetually, after the entire video has been buffered.

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!

I installed Firefox after the new update, and some YouTube videos (usually longer ones) won't load and show the error message in the title. I have Windows 10 N, but I installed the Media Feature Pack, and Flash is also installed and up to date. I have no trouble loading videos in Chrome, so it seems to be a Firefox thing.

Thanks in advance.
