Firefox Support Forum

I am running "Firefox Browser 93.0", and I have Windows 10 Pro Version 21H1, OS Build 19043.1288. I am unable to watch certain video's, as an example, the video in this link: [https://www.wandtv.com/news/illinois-.../article_24b92a86-32c4-11ec-a487-3bb3f17fa133.html] won't play. It use to work, but something has changed, not by me. It will play that same video using the "Edge Browser" so there is nothing wrong with the website. However, I can play this "YouTube Video": [https://www.youtube.com/watch?v=qAJSYk5wMiA] I also tried another link in their website, this is the weather link: [https://www.wandtv.com/weather] it starts to play, but then stops and nothing ever plays. Here is another link I tried on their website: [https://www.wandtv.com/sports/fans-ma.../article_f94f4ade-32e0-11ec-9351-ef71f52b96cd.html] It won't play either. But they all play in the "Edge Browser!" Any ideas on what changed and how do I change it back, so they will play? I prefer Firefox Browser to any other browser! Do you know what the issue could be? I appreciate your time! NiceSeeingYou

Hello,

I have the site espn.com bookmarked and for the last month or so it has been opening it's various foreign sites instead of the united states version when I click on the bookmark tab. It will switch to the UK and Mexico sites randomly when I click on the tab. The address is saved as the US version (espn.com) when this happens so I can't figure out why it's doing it. It doesn't matter if I use a vpn that says I'm in the US or just my regular internet provider in the US, the site keeps changing what country it chooses to open with. I noticed that every time I click the tab it will cycle between the various different sites for each country even though as I said before, the bookmark is set for espn.com. It makes no sense as none of my other bookmarks do this and it doesn't do it when I use Safari's browser. Is there anything on my end I can do to get this to stop or is it coming from espn.com's end? Thank you for your time and help. :)

I need to use Google Meet for a professional purpose. When I use is from the Chrome browser, I can present a specific tab on my desktop; however, I prefer to use Firefox as my default Browser. The problem is, when I use Meet on Firefox, the presentation options don't include sharing a tab. Is there a way to fix this, or do I just need to use Chrome when meeting?

Thank you.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.nextechclassifieds.com because this website requires a secure connection. www.nextechclassifieds.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. www.nextechclassifieds.com uses an invalid security certificate.

The certificate is not trusted because it is self-signed.
Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

This is a trusted website, been using it for years without issue. Used it a few hours ago to check my account. Only problem is on my pc, all other devices including people I've asked, do not have this issue. Seems to be a problem with the firefox browser only.

Hi! Netflix used to work great in Firefox on my Mac OS X 10.11.6 macbook. Now I've been getting an error message saying "Looks like your browser is no longer supported" when trying to play video on Netflix and it won't play. I noticed that it self-updated a couple times over the last few days but these updates did not solve the problem. I'm hoping that this problem can be fixed so that I can keep watching Netflix on Firefox, as I find Chrome and other browsers are very slow and laggy compared to Firefox. Thanks :)

When clicking on an article link in an email from Wired, "Header overflow" is the only thing that is displayed in Firefox. It worked prior to latest upgrade. The link works fine when using Safari. Here is the link: https://link.wired.com/click/26376218.29116/aHR0cHM6Ly93d3cud2lyZWQuY29tL3N0b3J5L2hvdy10by1wcmVwYXJlLWNsaW1hdGUtY2hhbmdlLW5vdz91dG1fdGVybT1QNCZ1dG1fc291cmNlPW5sJnV0bV9icmFuZD13aXJlZCZ1dG1fbWFpbGluZz1XSVJfRGFpbHlfMDExNzIyJnV0bV9jYW1wYWlnbj1hdWQtZGV2JnV0bV9tZWRpdW09ZW1haWwmdXRtX2NvbnRlbnQ9V0lSX0RhaWx5XzAxMTcyMiZieGlkPTVjYzlkZmViZmM5NDJkMTNlYjFlNWY5ZSZjbmRpZD0yMzU2ODE5NCZlc3JjPUFVVE9fT1RIRVImc291cmNlPUVEVF9XSVJfTkVXU0xFVFRFUl8wX0RBSUxZX1paJm1iaWQ9Q1JNV0lSMDkyMTIw/5cc9dfebfc942d13eb1e5f9eDe873c205

Fire fox updated t his morning now half my web sites I used yesterday come up with this PR_END_OF_FILE_ERROR, bing , yahoo, usps and faacebook just to name a few!!!!!! Not Happy!!!

I have Firefox 96.0.1. As of this morning, images will no longer load on any websites. The only thing that has changed since yesterday is that I followed some advice from the Washington Post on how to prevent scam emails. I have spent nearly two hours searching for and following advice to restore images on Firefox, but nothing has worked. I need more direct assistance!

It seems like something has changed recently, I don't remember having such problem before. As you can see on one of my pictures I have browser settings changed to always ask what to do with every file extension, yet encountering link to pdf file it loaded automaticly in special frame instead of showing just link to it. I included pictures of this frame, settings and another screenshot of the same website in Opera browser with similar settings where nothing loads itself.

Link to the problematic comment with auto-loading pdf: https://kodluch.wordpress.com/2021/09/30/30-09-2021-syria-2187-dzien-sprzatania-swiata/#comment-115906

Is there any way to block such pdf-frames in current version of Firefox?

WebGL has stopped working. I think this has happened with Firefox 91.

For example, http://webglsamples.org/aquarium/aquarium.html gives the error Status: WebGL creation failed: * tryNativeGL () * Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)

I'm running Firefox on Debian on ChromeOS.

On about:support, WebGL 1 Driver Renderer: Red Hat -- virgl WebGL 2 Driver Rendered: Red Hat -- virgl

There are no WebGL errors in about:support

I've tried the Troubleshoot Mode but that made no difference.

Hi! This will sound like an odd question, given that everybody seems to search for the opposite - but how could I DISABLE dark-mode in FF95.00?

I have my whole OS in dark-mode the whole time because of looks. I also installed a dark-mode theme on FF. Because of looks. But after the latest updates, FF decided to present a bunch of my favourite websites in dark-mode, too. Even at daytime - where I use my Computer.

Affected websites are, for example such "unknown" websites like "twitter.com", "spiegel.de" or even "facebook.com". It seems like they use some kind of a flag or token, which decides to use darkmode or not. How do I re-enable the light-mode (is this even a word?), not dependent of my windows / FF settings? Is there an add-on?

Firefox was just updated to version 91.0.2 (64 bit), and now the l;inks on Amazon Prime video no longer work. Many of the links take me to my Watchlist. I tried accessing the site using Chrome and Edge - no problems with those browsers. Firefox was working with Amazon last night, so this is something that happened with the recent update.

I have a new business website http://affordable-tutors.com/about-our-tutors and I tried to put in my video https://youtu.be/EQxd_cowXPg

but it gives me the following error. Website will not allow Firefox to display the page if another site has embedded it

What can I do?

Yes, I own all the rights for that video.

Does anyone know why I have been getting this error for the last week? I am using version 91.0 (64-bit) on a Windows 10 laptop.

When choosing Paypal as payment option on website, the Paypal login page loads. But after entering my login info I just get a continuous circle. Message at bottom is "waiting for c.paypal.com" then nothing happens. Going in again I sometimes get the verification pictures to prove I am not a robot, but then the same thing occurs. I have cleared cache and data, refreshed Firefox, re-entered Paypal login details, checked Firefox is latest version, disabled AntiVirus, checked tracking protection is standard, turned off AdBlocking extension for that page but nothing works. Using Opera browser Paypal opens immediately. So what's the issue here Mozilla? Any fix?

This issue is with me for some time now I guess 6 to 12 months, I have circumvented it by simply using other browsers that don't have the issue, it is only in Firefox.

I have noticed that it seems to be a reoccurring issue for many people reading through help topics.

At the moment I am using: Mozilla Ubuntu Firefox 91.0

 Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Starting Firefox in "Safe mode/Troubleshooting mode" through the "Application menu" -> "Help" -> "Troubleshoot Mode", doesn't fix the problem.

... "Did you check the date/time and time zone on your computer?" (As suggested in an older topic)

Automatic synchronization with an Internet time server, is set to "ON"
My "Time Zone" is set manually set to the correct "Time Zone"

Since the issue is only in Firefox and not in Chrome, Chromium or Opera, there is something that Firefox is doing that Cloudflare doesn't like or visa versa....

I have noticed in other posts that the blame is simply shifted to Cloudflare, but why do other browsers then not have this problem ?

Opening the no longer existing website (from another help topic here about the same issue), that is still known by Cloudflare, shows the problem if you got it too -> http://animedao.com/

See my uploaded screenshot to see it is only in Firefox.

Hello, I'm not sure if I chose the right topic above.

I'm trying to visit a site which is still using http. But Firefox is automatically redirecting to https, where of course it cannot resolve the site.

In settings, I have it set for "Don’t enable HTTPS-Only Mode". But still, Ff is redirecting.

I don't know. Maybe I should set for https only, and then enter an exception??

I have searched for a solution, but for every solution I find, when I look up how to do it, it says, before you try this, try that first. After about 5 rounds of that, I got too confused and gave up.

Oh, I also cleared the cache, but no help.

I've enabled all the extra info below. But let me know if you need any other specific info. Do you need the address of the website?

Thank you very much.
