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 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

    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

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.

When I try to make a bookmark none of my folders are showing. I can use the folders when linking to a bookmark but not when trying to place a new bookmark. I have many folders but the attached image shows what I get when trying to choose the correct folder to place the bookmark. Only the three options show even though I know all my folders are in the pulldown bookmark tab. I did have a computer glitch where many of my computer files somehow ended up in the trash including Firefox. I moved the trashed files into a new folder on my desktop and was able to recover the bookmarks by choosing the Firefox backup. My question is how do I get the existing folders to once again show when making a bookmark so I can place/organize the bookmark in the correct bookmark file?

This is a horrible web browser that crashes constantly and is slow as hell. Even Internet Explorer is faster than this, and I am switching to that browser and am never reinstalling Firefox ever again.

Hi,

I hope you are well.

I have set up 11 custom devices that max the min and max sizes of bootstrap grid system (xs-min-360w, xs-max-575, etc) to aid me with checking my website on various screen sizes. Is there anyway to export this list or better still to synch them with my Firefox account so I don't lose these settings?

I am using Firefox Developer Edition (101.0b6 (64-bit)) on Ubuntu 20.04.

Many thanks Kaz

I have credit card autofill enabled, because I do a lot of business online and it is very convenient. Maddeningly, it has started doing something I can't find a way to fix. I put the mouse over the box asking for a credit card number, the saved numbers pop up, I select one, and then the pop-up box disappears without filling in the credit card number. There has got to be a fix for this, but I cannot find it. Pls. advise...

I'm having an issue which is it possible for me to migrate the self distributed extension to AMO? as the version codes are clashing it's impossible for me to upload another version that will clash again.
