I updated to Firefox 35 recently and now HTML5 videos will not work. I do have NoScript, but disabling or removing it does not fix the problem. Switching to safe mode does not fix the problem. The problem is solved by using a fresh profile or deleting the prefs.js file, but this is not an option for me, as restoring all my settings from scratch would be a time-consuming hassle I'd rather not deal with.

I know the problem is with the update to Firefox 35 specifically because everything was working fine before and stopped working after. To be absolutely certain, I turned on my laptop that had the same exact extensions and settings imported to it from this computer with FEBE a while back. It was using version 34.0.5 and everything was fine with that version. I tested it with the Vine website, all videos worked. It also downloaded the update to Firefox 35 in the background and as soon as I restarted it, the HTML5 videos were broken.

It's definitely something Mozilla changed but forgot to alter/remove an old setting that's gumming up the works. If I could just figure out which line(s) in the prefs.js file was causing the issue, I would delete/modify it myself in Notepad.

For the record, I already had media.windows-media-foundation.enabled set to false. All videos that use Flash seem to work. I think Vimeo uses HTML5, but it's the only non-Flash video site I could find that still works. Flash and Java have been updated to the latest versions.

When playing a video in background / different tab, the picture (screen) freezes after a few seconds, while sound still going on.

Videos, like mp4 Vines, won't play in Firefox. Same with the media files like podcasts in rss feeds. All used to work fine. This is an intermittent problem with Firefox ( might be due to updates ) but it doesn't happen with IE or Chrome

If i uninstall VLC player or disable the VLC plugin, nothing happens If i have those installed but the VLC plugin is set to " Never activate ", i can right click on the video image, click " Play " and it opens in VLC player and works perfectly. If i have the plugin set to " always activate " then i see a black square and the message " the video can't be played because the file is corrupt "

Windows 8.1, Firefox 35.

This is an issue with Firefox and needs to be resolved.

How to prevent DOWNLOADING of video (not merely prevent autoplay) in Firefox

This may sound like word games, but I'm not trying to be funny, merely specific.

So I'm on a network with limited bandwidth. Therefore it's critical for me to understand what settings I can configure (if any) that will prevent the DOWNLOAD of video and/or large images from web sites.

For example, your basic site nowadays probably uses HTML5 and may use that vs. the old-style Flash plug-ins to embed video. And yep classic HTML links with references to image files for the images.

Back in the day you could configure a browser to ignore these references and then the browser would not even attempt to fetch the referenced image or video files. I've recently started using Firefox again, and I'm trying to learn how Firefox handles this in the HTML5 era (or rather what dumb users like me are supposed to do nowadays).

I'm noticing most of the help literature is regarding disabling settings of the auto-PLAY feature. However, due to my ignorance of modern Firefox, perhaps I'm reading it wrong, but most of it seems to involve disabling plug-ins that activate after the file is downloaded, not preventing the actual download. Similar to if I'm using Microsoft Word to view a DOCX file from a web site, uninstalling Word doesn't prevent the DOCX file from downloading. What I don't want to do is cheerfully disable the video playing while my browser still happily downloads the video in the background... because my main goal is not to avoid the annoyance of autoplay, but my goal is to conserve bandwidth on my connection.

FYI I'm using the latest version of Firefox Quantum on Manjaro Linux.

Thanks for advice anyone can provide in helping bring me into the "now" of modern Firefox, or who can point me to any further help articles or instructions to help educate me about this. If I'm over-reading and disabling auto-PLAY also inherently disables the downloading of the associated media, super, but that distinction is not obvious in any of the documentation I've seen so far.

Thanks!!

I have installed the 64bit Firefox, removing the prior Firefox program. Now, when I click on a mp4 and choose to open with, browsing to Program Files/Mozilla Firefox/Firefox.exe and clicking does nothing even when set as 'default' opening program. Am I to have the 32 bit installed into program files x86 or is there something else I need to do? Before when Firefox was installed, it was under program files x86, then the change to Quantum, (ran fine, I could use to view mp4 files), a computer crash with 'Cannot repair member file [l:30{15}]"mozilla.browser"', a new install with change folder 'old firefox', removed prior install of Firefox (one with older install date), now have issue that can't use to open mp4 file from computer.

Flash player is either screwed up or something else - or Firefox is blocking videos. Having experienced problems (videos just sit there or won't load at all) I've just uninstalled Flash Player and am attempting to reinstall a new version - but it won't let me. Seemingly there's another version being loaded - but no way can I find that or know what's happening, so I'm stuck.

The whole thing stems from my inability to watch any videos on Firefox - not even YouTube, BBCi LiveLeak clips or even porn. Yesterday everything went well but today I can't even see gifs on Imgur. What the hell is happening? Why is Firefox blocking me?

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.

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.

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.

Last night around 8pm I watched a Youtube video without a problem, closed my browser and did other things for awhile. When I got back on at about 10pm and tried to watch another video the video suddenly stopped a few seconds, gave me "An error has occurred" then suddenly the video started again at the point it stopped but now there was a little bracket at the stopping/restart point (see image attachment). This wouldn't be a problem if it happened once in awhile but since last night it happens with EVERY video regardless of length or quality. In fact, sometimes it forces me to watch it on the highest quality and makes the other options unavailable. If I try to refresh it takes a LONG or simply refreshes forever. And heaven forbid I should have any other windows or tabs open when this happens because they'll suddenly stop loading or get REALLY laggy. I have no choice but to watch Youtube in IE which works surprisingly well and doesn't do any of the crap I've just described.

Everything is up-to-date. I have cleared cashe, temp files, cookies and history. I have not downloaded or installed anything in the last 24 hours. I've asked other people who use FF about this and they all say it's fine so I don't know what to do anymore.
