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 ?

Thanks

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?"  :laugh:

I was wondering if someone was going to comment on that - it was on my main page - I like the Jimmy Fallon stuff ;)

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.

Test Tube

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.

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.

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.

I use ublock, and disabled it and no difference

I appreciate it -

v37 & 38 are completely compt with MSE and I already hate that tweaked in about:config

Thank you though

 

Just tried v38b on a Windows 10 VM. 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....  :D

 

^ 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).

    • Of course the problem was Secure Boot's new certificates. Install media created by the official Media Creation Tool is already signed with a valid certificate from Microsoft, so maybe that certificate isn't "up-to-date" enough for machines with the new ones installed in the UEFI. There's really no other logical explanation.
    • Here is how I fixed Windows 11 not booting after clean installation by Taras Buria Story time. A couple of weeks ago, I experienced a very odd thing with my computers. I was trying to reinstall Windows 11 on my primary device, and everything was going smoothly until the installer performed the first restart. After that, my computer entered the boot disk selection screen instead of continuing the setup process. Huh, that's odd, said I, and selected Windows Boot Manager only to see it fall back into the same screen right away. Then I tried booting from the USB drive with the same result—the PC kept returning to the boot device selection screen, and removing the drive would send my PC to UEFI, again, with no way to launch Windows 11. I fired up my spare laptop, which has been sitting unused for quite a while, to see if I am dealing with a defective USB drive. Nope, Windows 11 installed and started without issues. After trying another drive and checking all the possible settings in UEFI, I decided to try disabling Secure Boot. Lo and behold, Windows 11 started as it should have been in the first place, continued the setup process, and reached the initial setup screen. Victory! After I finished the setup and applied all updates, I re-enabled Secure Boot, and Windows 11 started without issues. Some time later, I tried reinstalling Windows 11 on my laptop only to experience similar issues, with UEFI claiming a Secure Boot violation. I checked whether the drive works on my main PC, and yes, it installed Windows 11 without errors. I scratched my head, went to UEFI, turned off Secure Boot, and installed Windows 11 without issues. After that, I enabled Secure Boot. Note: I used the official Media Creation Tool app for my USB drive. Also, UEFI was properly configured for Windows 11, including no Legacy Mode, a GPT-partitioned drive, and TPM and Secure Boot enabled. From my experience, if you are dealing with similar symptoms, I recommend two things: If you use old Windows 11 install media, create a new one with the latest Windows 11 release, especially if you know your PC already has the latest Secure Boot certificates. If you cannot create a new one, turn off Secure Boot, complete the installation, download all available updates, and then re-enable Secure Boot in UEFI. Note that you need to turn off Secure Boot after installing Windows 11. Otherwise, the installer won't run, claiming a hardware requirements mismatch. I believe the problem hides in Secure Boot certificates that expire this month. Microsoft is currently rolling out new certificates, and maybe a mismatch was causing these issues for both of my systems. I am out of my depth to make a definitive statement; this article is flagged as "Opinion," as I only share my experience and some tips on how to fix the problem. If some of you possess deeper knowledge and understanding of the situation, please share it in the comments. As for everyone else struggling with computers not booting after a clean install, the two steps above should get you out of the pickle.
    • I gave the tool a chance the other day to make a USB. An hour later it was stuck at 0% downloaded. I downloaded the official ISO, downloaded Rufus, and made the USB myself in 15 min.
    • <Moved to software discussion and support> I've got fond memories of Winamp. Changing the skins, the different visualisations etc. But now I just need a simple music player. MSN messenger would be another one, MSN Messenger Plus (I think?) offered so many different plugins. But again, it probably wouldn't work for me these days. And then there is miRC. i think it's still going these days, but lord i had fun with that back in the day. Now it's mostly stuff like Discord, WhatsApp group chats, Signal, Telegram... /me is showing his age...
