Getting errors messages like;

An error occurred. Please try again later. (Playback ID: esTXxYqBr25ETVYS)

Tried resetting FF, clearing cache and cookies etc. to no avail.

This started about a week ago.

Youtube webpage is working properly, just embedded videos are fubar.

Grrrrrrrrrrrrrr

I have spent hours, literally, trying to fix this issue by following firefox community help guides yet nothing I've found has solved the problem. I can fully utilize youtube, with similar addons installed , on google chrome and microsoft edge without any problems yet firefox will allow only videos to be watched on youtube - nothing more. When I try to comment it says: Returned error , when click on the (save) button; nothing happens, when i click on my account icon a blank window opens with a circle spinning in the center endlessly - - the extent of functions is limited to, watching videos . I've manually installed Adobe flash, I've tried disabling the polymer function, I've tried the safe mode with my firewall disabled (I made sure that the microsoft firewall did not enable when I disabled Kaspersky), I went into about:config and did all the adjustments... there is quite a number of other things I did over the course of three hours. In the picture I have one picture showing my firewall/addons disabled with firefox in safemode while in the other picture the firewall/addons are enabled. System Information

Hello. I am having the same issue as another user, but they flagged their question as solved so I'm making a new one just in case.

I can't login properly to YouTube, only in Firefox, even after clearing cache and cookies and disabling add-ons/running safe mode. I can login to my Google account, view my playlists and recommended videos (although the main page with recommendations only shows 5 lines of videos and when scrolling further is not loading). I can't make any edits, for example add videos to the "Watch Later" playlist, that require a login. When I click login, Google shows the 405 error "The request method GET is inappropriate for the URL /youtubei/v1/browse/edit_playlist. That’s all we know." or with other URL, depending on the action taken.

What can I do? Thank you.

A week ago installed fresh win 10, downloaded Firefox, logged in my firefox account. got my bookmarks, password and other good stuff synced in and at some point i recognized that my Youtube dosen't work right(issue exist only in Firefox, only on 1 PC)so here is a deal: I log in my google accout, open youtube page, it shows my subscriptions, recomended, playlist and other stuff except notifications, and if i like a video it dosen't add to "liked videos" playlist, in fact i can't manage any playlists at all and if i update a page it shows that i'm no longer loged in and i can't log out ither because page dosen't look like it should(simply not showing UI for account managment, only "dark theme","language" and other crap related to page) in Opera and even Edge everything works like intended. I used win. defender and other anti-virus soft to scan my PC - found nothing, there is no addons or anything like that, i completly removed evrything Mozila related and instaled it back - dosen't fix anything.

Just installed the update to v79 (64 bit) on Win 10 v2004 (64 bit). I when Firefox reopened, I went to YouTube to watch a video and play would not work. You get the "thumbnail" pic of video and then the screen goes black and an error message appears saying the video cannot be played. I turned off the Hardware Accelerator, rebooted, same issue. Restarted in Safe Mode, same issue. Updated all Plug-Ins and Extensions, same problem. I can play YouTube videos in Chrome and Edge without issues.

Recent updates are causing problmes with gmail and video sound.

Using URL https://mail.google.com/mail/u/0/#inbox I keep seeing a not connected, trying again message. Closed tab and opened new one with same URL and just get blank white screen. Works fine on Chrome.

Sound does not work on Youtube or Amazon Prime video sometimes. Reopen same URL in Chrome and all is good again.

BTW, it would be useful if Firefox browser upgrades could be skipped. Sometimes one needs to open a browser in a hurry but no can do because Upgrades seem they are going to upgrade, user wishes dismissed. Maybe updates would be a better word than upgrades. Not as bad a Windows but y'all don't want to be like them, do ya? They are the McDonald's of software, they sell a lot of it but it ain't very good.

Thanks for letting me whine. I will go back to my safe space now...

On 77.0.

Noticed that after last update, opening a new tab with audio on the previous tab (such as a YouTube video playing) causes the audio to pause/stutter each time a new tab is opened.

No other changes to this system, and good amount of resources available in each test. Would be great if someone could quickly repro. (I am not discounting a machine-specific cause yet.)

Since yesterday, youtube videos on firefox don't load, they work on other browsers I have tried, turning hardware acceleration on/off made no difference, any ideas?

I'm having a weird problem where 4k videos that are scaled down to say the normal YouTube player size look terrible, hard to find the right word to explain it, but edges are jagged. It improves a lot if I full screen the player to presumably closer to 4k dimensions.

Changing playback to 1080p looks better than 4k, again I'm sure it's to do with scaling.

• I don't have this problem when testing the same videos in Internet Explorer.
• It's not just my videos, other peoples videos are doing it to.
• Updated to the latest version of Firefox.
• Updated my GPU drivers (MSI Nvidia GeForce GTX 1660).
• Tested in Firefox safe mode and disabled/enabled hardware acceleration.

I'm running out of ideas, so any suggestions would be greatly appreciated.

Since Firefox 73 was released I noticed after upgrading that Firefox became insanely slow on a significant number of websites. For example youtube.com or finance.yahoo.com were really slow at loading compared to Firefox 72. CPU usage on one of my cores goes very high.

This page for example would load the main screen fairly quick then it would stall while it loads all the stock widgets on the page which it doesn't do with Firefox 72 :

https://finance.yahoo.com/quote/SPLK

In general I've noticed an overall loading sluggishness even with simple pages like google.com etc. Just not as snappy to load.

In all cases Firefox 72 and Chrome work fast and snappy. Tried Firefox 73 and Firefox 76+ and they run awful.

When I first noticed the issue back when Firefox73 was released, I gave up and rolled back to a Firefox 72 backup and thought it was probably a bug that would be sorted later. Tried again today with Firefox 76 and I still have the same issue so I have had to roll back to Firefox 72 again.

Things I have tried that have NOT helped :

Disabled all addons/extensions Set Default Theme Disabled DNS over HTTPS Cleared cache/cookies Deleted content-prefs.sqlite Disabled hardware acceleration Tried different values for content process limit Disabled smooth scrolling

Can anyone help please or am I going to be stuck on Firefox 72 forever?

Thanks.

What is going on with using YouTube on Firefox? All of a sudden, the last few days, I keep getting a yellow bar saying that there is a error with Script, Then I find out that the current Firefox does not use Java Script.

This is very annoying, I've and tired of getting this error message every time I open or close a YouTube video. I would prefer that I be able to watch YouTube on Firefox, but I will not watch it much longer if this is what I have to put up with.

I think that if you don't want to allow Java than you provide a platform that with run YouTube without issue. I've used Firefox for sense the early 90s and you are well know for making changes that don't provide a user friendly environment every now and again. If you can't provide a error free means of watching YouTube, I will be looking for a Browser that does. Even though I hate being tracked by Google. I am sure they track my us of YouTube but at least I don't have to put up with poor viewing or have a video interrupted because of Java Script not being used.

Firefox latest version is not able to play youtube videos at 1080p 60fps, while the old version Firefox 56.0 plays them correctly, without blocking images or flickering. The system is Windows 7 x64 updated with 8-core Intel processor and AMD HD RADEON 2gb DDR5 dual GPU video card

I already reinstalled firefox. When I go to any site that has videos all I get is this grey screen (see picture). Its not just youtube but any site that has videos. I am not sure how to fix it. I am running the most up to date firefox.

when i'm trying to watch a video on youtube, about half of the video is just white (screenshot attached). Not sure if this is a feature, although I highly doubt it. Already tried in safe mode, and it still doesn't work properly.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.youtube.com because this website requires a secure connection.

What can you do about it?

www.youtube.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

In the last 24 hours or so, embedded youtube videos on Reddit are mostly not playing back. I get the "playback error" but the website itself works fine.

I've found other posts on the same error but not a resolution that works for me. I know Firefox updated a few days ago but it didn't start then, and I haven't changed or updated anything else. (Everything is up to date)

They used to work. When I select a program Youtube TV (after logging in) it just buffers. It will work on Chrome. Weather.com maps animations don't move today but they do on Chrome. Is this a common problem? Thanks

I upload to You Tube on a daily basis and need a fast upload system and it did appear to work but for some unknown reason it has reverted to stalling and taking ages with no results. I need this to work urgently?????
