Firefox-Hilfeforum

Recently YouTube videos have stopped playing when I'm using the Firefox browser on Windows 10. This has occurred both on my laptop and on my desktop computer. The player, surrounding website, comments, description, etc. all load correctly. The video does not, instead displaying either the video's thumbnail and a buffering symbol, or a blank black screen and a buffering symbol. The time codes on the video load correctly. Ads do not play either, and instead after about 15-30 seconds of buffering the "skip ad" button appears in the lower right hand corner of the video. Videos play normally on both Chrome and Edge, and all other media content appears to load correctly (music/spotify, videos on social media websites, etc.)

So far I have tried: - Running Firefox in troubleshoot mode - Refreshing Firefox - Clearing the cache - Disabling and re-enabling hardware acceleration (didn't work either way) - Uninstalling and reinstalling Firefox - Rebooting my machine - Waiting for the problem to fix itself (it's been two weeks on my main desktop/tower and it's still not working).

At this point the only thing I haven't tried is messing with advanced config settings, and I'm avoiding that since I have no idea what any of them actually do (despite what certain reddit threads recommend).

As far as I'm aware, no specific update to either of my machines or Firefox has preceded the issue appearing. It's been going on on my desktop computer for about two weeks, the problem just started on my laptop last night.

It's worth nothing that I usually use UBlock Origin, Simple Tab Groups, and Facebook container. Those extensions are not currently installed since I had to reset my browser in the process of trying to fix the issue.

I can also confirm it's not an internet issue; speed tests show normal download/upload speeds for my wifi, and those have not varied since the issue began. All of my drivers are also currently up to date.

Hi, I'd like to disable that annoying animation when going to fullscreen (by hitting F11). Supposedly, setting the following should work:

Go to about:config

Set: full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 full-screen-api.transition.timeout 0 full-screen-api.warning.delay 0 full-screen-api.warning.timeout 0

Restart

However, this does not have any effect in Firefox 94.0 on Ubuntu. Is this a bug/regression? Or is there some other way to disable the animation?

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, it won't autofill. In Settings, the box to autofill is checked. This has worked a hundred times before, but stopped working a few months ago. How do I get the autofill to start working again?

Why can't I online shop with Mozilla? For months now I have had to go to another browser to use websites and make purchases. It doesn't happen 100% of the time, but enough to have me consider using a different browser permanently. I have used Firefox for years and don't want to change. But, when I need to purchase things or even pay bills and it won't let me continue on to a site, it's an issue. And yes, I have cleared cache and cookies and it doesn't seem to make a difference.

Specific examples: I logged into a store that I have purchased from before to make a new purchase. I can browse the website, but when I add to cart and try to check out, nothing. No message, not anything to help me know what the issue is. I go to Edge, pull up the site, and complete my transaction.

Today I tried to log onto a site that we just set up an account with yesterday. It's to be a guarantor on an apt for my son. We set up the acct and went today to finish the requirements and it won't let me access it. Just keeps scrolling. I go to Edge, log in with no trouble.

Lately, Firefox unchecks the 'use autoscrolling' and 'play DRM-controlled content' options sometimes (but not every time) when it starts. Other settings don't seem to be affected. It does seem to unset both at once, never one or the other at a time.

I have begun using Firefox routinely on two computers, both signed into the same sync profile. My best guess is that maybe one profile is overwriting the other? Both of these options are set on the second system, but maybe there's something going wrong with the sync?

Thanks, Patrick

I am looking for suggestions/work flows for migrating existing Mac's from the standard firefox release to the ESR version. I am looking to manage these all under 1 update cycle. A couple of current problems:

1. On a system with the standard version already installed, I can't find a way to upgrade to the ESR version without uninstalling first.
2. Once I would do an uninstall and then an install of the new version, I am prompted that I have launched an older version of Firefox and that I must create a new profile. How can I do this without loosing all users bookmarks, extensions, etc?

Thanks!

FF 100 on Linux Mint 20 cannot access any websites. Tor can. TBird email can. I'm on an older Ubuntu with FF 94 writing this. How do I get back to previous FF? URGENT!!!
