Firefox Support Forum

Hi there,

since the beginning of June (probably the update with the PiP notification) I noticed that a lot of specific Youtube-videos are endlessly loading (the spinning circle animation) and not showing any controls (play/pause, next video, etc.). It's not like I could try multiple times and sometimes videos load and sometimes they don't, it seems to be specific videos, but I can't figure out what differs them from others. Examples that work: https://www.youtube.com/watch?v=Yqy7_zUKyNQ https://www.youtube.com/watch?v=ftuctYN60j0

Examples that do not load: https://www.youtube.com/watch?v=FF3Dr3_h0Hw https://www.youtube.com/watch?v=LAN1LXO1eG8

Generally I could say that about 60% of the videos aren't loading. I tried them in another Browser and also inside of other Software (Discord, Mattermost) where everything seems to work just fine, it's just my Firefox having issues and I really don't want to switch to another browser.

I really hope somebody can help me, I tried finding a solution, but all the other issues seem to differ from mine or are Mobile-issues.

So I've been using firefox for a while now, and I really like it, but in the past few months it has suddenly decided that my browser is out of date (not the case, I'm running the latest update) and unsupported, even though it says firefox is supported. This happens on a lot of different sites. I tried resetting my useragent and clearing my cache and cookies, but nothing seems to have happened. I still get the bug. I submitted to webcompat too.

Please help, its super irritating to deal with, and I don't want to have to switch browser.

I have been using firefox for years and am very happy with it. I have a Dell optiplex 7010 desktop. I am running Ubuntu 18.04.4 LTS. I do not have a firewall turned on. Apparently, my desktop browser was updated to Firefox 78.0.1 (64-bit) on 7-1-2020. Since that time, I have been unable to access any websites from Firefox including mozilla.org. I am connected through WiFi. After downloading the Opera browser I have been able to access any website with no problems. I read community troubleshooting on this issue and tried various fixes including turning off IPv6. I read the community article about turning off my personal firewall. I was unaware of using any firewall so I installed Gufw Firewall 18.04.0. Running this program shows my firewall status is "OFF". I checked my AT&T modem and could not find any firewall settings that specifically mentioned Firefox. I would like to continue using Firefox since I use it on my phone and laptop also use it.

My laptop is a Dell Vostro 1520 running Ubuntu 18.04.2 LTS 64 bit. It also accesses the internet through the same WiFi. It currently has no problems loading web sites with Firefox version 78.0.1

Please help.

On some sites and a NextCloud installation, I suddenly cannot click on some links that report following error in the console: Uncaught Error: Permission denied to access property "apply"

   jQuery 7
   clear searchprovider.js:292
   attach merged-index.js:11661
   jQuery 8
   _setCurrentDir merged-index.js:5820
   changeDirectory merged-index.js:5752
   actionHandler merged-index.js:3432
   action merged-index.js:2894
   _onClickFile merged-index.js:4757
   Underscore 3
   jQuery 2
       dispatch
       handle

I've checked and disabled add-ons to see if these were blocking somehow, but no result. It worked fine before, so my suspicion is something changed in FF78? Thanks!
