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.

On my new desktop I want to enable the feature that does the following.

I want to be able to view a webpage and then ctrl click or M3 click a link and I want the new link to open in a new tab but REMAIN on the current webpage.

I have unticked >When you open a link, image or media in a new tab, switch to it immediately under settings already.

browser.tabs.loadInBackground under about:config is set to True.

When I create a profile with a name and then open that profile, the first thing I do is log in to Firefox Accounts if I need to. The problem is, if I use the name I want to use, I get what you see attached. Why is this happening?

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

I did a refresh yesterday and lost my passwords. I have another computer where the passwords are functioning and I have the "old file" but I don't know how to use it. I clicked on the old file, but just came up with another file called EP7i0nok. It doesn't do anything but it just opens up and it doesn't have anything to restore data.

I keep getting this Problem Loading Page message:

Secure Connection Failed

An error occurred during a connection to www.google.com. SSL peer reports incorrect Message Authentication Code.

Error code: SSL_ERROR_BAD_MAC_ALERT

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

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

I want to download a pdf document from the internet. i used to be able to click on a download icon in the upper right hand section of the screen and it would download to my download file. Now it won't. I am using Firefox 100.

Thanks

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 am running Firefox 100.0. When I go to certain websites reCAPTCHA is preventing me from accessing the site. Error message: Please upgrade to a supported browser to get a reCAPTCHA challenge.

I enabled Pop-ups for those sites to no avail. Zoom.us and sedar.com are 2 websites causing problem but only on one computer.

I uninstalled and reinstalled Firefox, but no difference. I disabled Norton 360 and made no difference. No problem if I switch browser.

In the past few days Firefox has stopped showing html pages on my other partitions. Has Firefox changed the way they are doing things or is this a new bug?

The screenshot below shows a web page I regularly use that I keep snippets and brief programming notes. It and all links on all partitions except the root drive are no-longer accessible.

I have used Firefox for over 10 years and never had this happen.

Any ideas what may have happened?

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

Hi, I cant log in to any plusnet pages, this is not just Firefox other browsers do the same. I get a message Secure connection failed. All other websites seem ok. Even private browsing is OK but no PLUSNET. I use Firefox 100 and search with Duck Duck Go. Please help as Plusnet can't. Many thanks I.M.

I'd like to permanently delete an account that was set up on a former employers email address (email which I can no longer access). Unfortunately I have no secondary email address recorded in the account and all the options on my account page require that I authorise any changes from the email account which I can no longer access.

Is it possible to delete the account?

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.
