Firefox Support Forum

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.

I keep getting this Problem Loading Page message:

Secure Connection Failed

    I've been through the Security settings and can't seem to find a fix. This seems to have started with the last update...

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?

I have several windows open, each with different type tabs--i.e., dancing, gardening, etc. How do I save these windows so I can open them when I wish? I don't need them all open at the same time and having them all open uses up too many resources. Thanks in advance, Elizabeth

I run into this at least once a week, on sites that I know are completely legit, including sites that I recently visited successfully. Once it starts happening for a given site, I can't figure out how to get past it and regain access.

I've asked other folks to visit the same sites at the same time, and they can get through. I've tried accessing them on other devices on the same wifi network, and get through just fine. But I can't get to them any more on my main computer.

I've tried clearing cache and deleting cookies and data, and that hasn't helped.

I'm on Windows 10, and (now) Firefox 100.0. I'm in the UK, using Sky internet -- I don't know if that's relevant, but I didn't notice this problem before I moved here (from the US) last year.

As I said, I can still access the sites on another device (an iPad) on the same wifi, so I don't think it's the firewall in my router.

I don't have any antivirus installed -- just using Microsoft Defender. And I'm not using a VPN or anything like that. My browser privacy setting is "Standard"/

The only extensions I have installed are Facebook Container and LastPass.

What can I do to fix this? It's breaking the internet for me.

Firefox 100.0 randomly hangs. Doesn't seem related to particular web site or web page. Is happening with increasing frequency (e.g. every 5 minutes or less).

Browser is completely unresponsive to mouse. Even title bar functions are hung. Must use Task Manager to Firefox end tasks. is happening on multiple independent PCs.

Long time Firefox user (10+ years) about to throw in the towel and go with some other browser unless someone can help with this serious issue. Please help..

Thanks

The page https://onedrive.live.com/ just hangs,as does my personal account page, though they open fine in Edge, so clearly it is a Firefox problem and very frustrating.

whenever i want to search something, if i don't put @ (ex: @Google) it will assume that i am typing in a URL. for example, if i type "cats" in the search bar, it will direct me to www.cats.com instead of searching up cats. because of this i have to put @google before the search term and this is extremely annoying. how do i disable this?

I use Firefox and have saved my User ID and Passwords for my ATT email (https://currently.att.yahoo.com/) and my ATT account (att.com). It was populating these fields before but now the User ID wont populate and I have to type the info in. The Password populates OK. What happened and what can I do to get it to work?

love firefox as my browser, but get soooo aggravated when I have to revert to google or some other browser to be able to login to a website, tv channel, bank acct etc.

why is that? I dont trust anyone else but firefox!!!!! why cant I login with no problems?

thanks

My browser updated and I seem to have lost all of my saved passwords. I signed in but none of them seem to be saved. Not sure how to get them back or where they went. Is there a way to recover or find them?

Hi, Could you recover for me last session, which I was used on my account? I accidentally logged off, before I opened last session on the new computer... please advice. Best regards, Krzysztof

This extension has attached itself to Mozzila/Firefox moz-extension://b8b74ec4-b566-444c-a67b-cc919887caaf/newtab/index.html, and it's making them act negatively. Slowing down just about everything, from slowing down my bootup to redirecting my web pages and giving me logging in issues. How can I correct this issue.

after upgrading to the latest version of fire fox I cannot access the router setup page. I think that the versions after v97 require TLS 1.2 or later. My router apparently does not support this. How can I access my router to update it's firmware. If I can't access the setup pages. Is downgrading to a version before v97 an option? is there any other work around. I want to establish a http:// not https:// connection with the router.

I have been using Firefox as my browser for as long as I can remember and yesterday it became semi-unresponsive (would not load). Then after restarting my computer and doing everything else I could think of - I got it to load and my previous session was restored. All the tabs were there . . . but none of them would respond. In CONTROL PANEL I even tried REFRESHING Mozilla Firefox short of Uninstalling. (That did nothing.) I tried downloading the latest version. It installed . . . , but, the old one is GONE. The new one DOESN'T WORK. In the search box it suggests youtube, facebook, etc. . . . NONE OF THEM WORK.

HELP !!!!!!!!!!!
