T3X4S Posted May 6, 2015 Share Posted May 6, 2015 Since v38 has forced HTML5, I can not watch a single video now. I have had this problem for a while and cant find the culprit. Only way I can watch a vid is via Flash. Furthermore, if someone were to embed a video from Youtube into a webpage in neowin, I would not be able to watch the vid, I would have to go to YouTube to watch that video... via the default flash player... but now, that isnt an option. When I click on a video, I get the white-ish grey circles rotating, but it never stops, and the video never starts. If I hover over the placemarker to advance somewhere in the video, I see the little thumbnail over the placemarker, but when I click Start - nothing happens. I have disabled addons to see if that was causing it - no change. I have switched to Chrome now, but would rather FF work correctly. Anyone have any ideas ?

vanx Posted May 6, 2015 Share Posted May 6, 2015 Yep, it's YouTube's way of saying "What is wrong with you? Why are you watching Ariana Grande stuff?" T3X4S and DConnell 2 Share Link to comment Share on other sites More sharing options...
cork1958 Posted May 6, 2015 Share Posted May 6, 2015 I guess that's what happens when you want to run beta software! Expect issues and bugs. Link to comment Share on other sites More sharing options...
T3X4S Posted May 6, 2015 Author Share Posted May 6, 2015 I guess that's what happens when you want to run beta software! Expect issues and bugs. It was the same with 36, and 37. If you read my original post, you will see I mentioned it has been an issue for a while, but before I was able to select the default flash player. Yep, it's YouTube's way of saying "What is wrong with you? Why are you watching Ariana Grande stuff?" I was wondering if someone was going to comment on that - it was on my main page - I like the Jimmy Fallon stuff Link to comment Share on other sites More sharing options...
Pikey Posted May 6, 2015 Share Posted May 6, 2015 I was having a similar problem a week or so ago with a 'nightly' build but one of the updates along the way sorted it! ... (Youtube seemed to be OK though?) I'm on *40.0a1 (2015-05-05)* at the moment ... maybe you could try the latest 'nightly' out? Link to comment Share on other sites More sharing options...
torrentthief Posted May 6, 2015 Share Posted May 6, 2015 maybe try creating a new profile. Also try uninstalling firefox first before deleting profile then re-install with a new profile. HTML5 video rocks, i'm glad flash is dying, hope you sort your problem though. T3X4S 1 Share Link to comment Share on other sites More sharing options...
Ace Posted May 6, 2015 Share Posted May 6, 2015 Have you tried an add-on like the one below to force videos to play with Flash Player? https://addons.mozilla.org/en-US/firefox/addon/youtube-flash-video-player/ Link to comment Share on other sites More sharing options...
T3X4S Posted May 6, 2015 Author Share Posted May 6, 2015 Have you tried an add-on like the one below to force videos to play with Flash Player? https://addons.mozilla.org/en-US/firefox/addon/youtube-flash-video-player/ Yes I did - unfortunately no difference. Here is a weird update.... I clicked on a video and instead of seeing the circles rotate then do nothing - I just sat there, and after about 10 seconds, the video started to play, then stops after 1-2 seconds with an error. I click on the "about this error" and it says there is no information about the error. I went to YouTube's TestTube site, and tried the new player - no difference. I will try the tips mentioned here Thank You FWIW - I also loaded the new player (I think its supposed to be tweaked for 4K @ 60 fps, and HD stuff - it performed perfectly on chrome - I like the new look of it too, even if it is subtle.

Jason S. Global Moderator Posted May 6, 2015 Global Moderator Share Posted May 6, 2015 OP - just throwing my 2c out there. I have the latest official build, v37, and have zero issues with Youtube. I even tried that Test Tube stuff you linked us to. It works great. What i could try is v38 in a VM... i just think your computer might have another underlying issue that isnt related to FF directly.

purrcher Posted May 6, 2015 Share Posted May 6, 2015 It sounds like the "mediasource:" script is being blocked on your system. Do you have a script blocker like noscripts installed? If so you need to allow "mediasource:" and then on youtube I think it will be "googlevideo.com" will show up and that will also need to be allowed to run html5 video's on youtube.

PanzerFury Posted May 6, 2015 Share Posted May 6, 2015 I don't think that newest versions of Firefox have MSE enabled by default, even on Windows. You can check if your browser supports MSE extensions here https://www.youtube.com/html5 Anyway, to manually enable this feature, you have to go to address: about:config find the key: media.mediasource.enabled and set it from false to true. That should fix your problems. Link to comment Share on other sites More sharing options...

No issues w/ the standard player or the 'new' player. Thanks Jason - I appreciate you going through all that just to help me. UPDATE: OK, this is just weird - now it works! I havent been able to get it to work for a week or 2, now - suddenly it works through the new player However, I want to use my addon that automatically selects the highest res the video supports - and it isnt working. But that is easy to fix with a different addon - the main thing is now I can continue to use FF This is one of those times where you are totally confused as to why something stopped working, then started working again, but you dont care because it is working....

Pupik Posted May 7, 2015 Share Posted May 7, 2015 ^ What addon was that? I use YouTube Center (the developer version) to always select the highest quality: https://github.com/YePpHa/YouTubeCenter/wiki/Developer-Version Have no issues on Firefox 38 the latest beta (9 I think). Not with the new player or the old one (all html5, for the 60fps support). Link to comment Share on other sites More sharing options...
