Can't connect with the just downloaded version 66.0.4 to virtually any site - not to Google, not to NYT, not even to Mozilla - Firefox won't accept ANY certificate! Following errors appear (examples): "Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to addons.cdn.mozilla.net because this web site requires a secure connection. What can you do about it? addons.cdn.mozilla.net 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. The issue is most likely with the web site, and there is nothing you can do to resolve it. If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

Or: Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to www.nytimes.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. What can you do about it? The issue is most likely with the web site, and there is nothing you can do to resolve it. If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

The explanation is as follows: Someone could be trying to impersonate the site and you should not continue. Web sites prove their identity via certificates. Firefox does not trust www.nytimes.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates. Error code: SEC_ERROR_UNKNOWN_ISSUER

No problems whatever with other browsers. I'm sending this with Safari.

I have encountered one web site that has several pages that display as graphics instead of text. I have visited this site before several months ago and the display was accurate then. The first image is how it looks now. The second image is how it looked several months ago. I am running Ubuntu 20.04.2 and Firefox 89.0.2. It's very strange that this is the only page that displays this way. I checked the page in Chromium and it displays correctly in that browser. Is this Firefox or quirky html?

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.

Since the most recent update, Mozilla Firefox shows screen errors on many websites. Same after reinstall. All sites appear OK in Chrome, Opera, Tor, etc.

Please send instructions for fix.

Thanks

Since Firefox was last updated, I now no longer have the ability to access some websites such as Google, Wikipedia, and Amazon without Firefox prompting me to type something to search within those sites even though all I want to do is go to the home page.

I can still get there by typing http:// in front of it but I shouldn't have to and if I change the settings to add the search in the toolbar and then try going to "amazon.com", for example, I'm still being prompted to use the address bar to search.

Is there a way to fully disable this prompt so I can type in "google.com" or "amazon.com" without getting the search prompt?

I got this error-code on my homepage: 55e4-a579-582e-c5e4 and Error 400, The homepage works in Google, Edge, Opera etc but do not work in Firefox. What to do next?

A few weeks ago the product reviews at Costco.com disappeared. I spoke with Costco today and they said they could see them and that I should switch to Google Chrome for better results. I tried turning off the privacy, no trackers on their site but it didn't help. Logging in or not didn't make any difference. AdGuard 7.6.1 is disabled on Costco's site. The 5 star rating system woks fine with Amizon and other sites. I am also using Norton 360 if that makes a difference. Any solutions?

Since the update to the new Firefox (92.0), quite a umber of sites cant load anymore as a secure connections cannot be established. This does not pertain some ark web sites, but sites from reputable companies which had previously loaded without issues. Indeed, the mobile browser still happily displays the sites now forbidden by Firefox.

I found that an update of Edge created equal same issues with that browser.

First, the problem does not occur using Chrome or Safari. On one site I visit regularly I am no longer able to use the PM and comment functions. I have checked with the site's webmaster and am confident the problem is not at their end. Suggestions short of deserting Firefox?

Facebook does not load. Error message: "Sorry, something went wrong. We're working on it and we'll get it fixed as soon as we can. Go Back Facebook © 2020 · Help Center" I know it's not Facebook as works fine on my Android devices. Firefox has been very unstable for months on Windows 10! Fix it!! Egad!! I got locked out of my Banks website. Uninstalled and reinstalled Firefox and problem solved. I am refusing updates cuz I think it was an update that caused the problem.

whenever i log into a official site such as Georgia DOT or Dish Network as i did recently, it is telling me that the Google (that is used as a search engine) is out of date and must be updated. as well, if i try to go to Netflix it tells me the DMR is out of date. computer set for auto update so i don't understand why. please help.. thank you.

I have a home website that was written using php well over 10 years ago. Except for family updates, it has changed little and displayed correctly using firefox and other browsers. Firefox is my preferred browser. A couple of months ago, it stopped displaying correctly in firefox but continues to display correctly w/o issues in Edge, and other browsers.

I note it displays in a basic form in firefox, links to other pages and content are shown and operable, but not displayed (correctly) as it does in Edge and others. I am on the latest version of Win Pro 10.

I posted the problem the end of August and received a number of suggestions. I went through the steps suggested (using troubleshoot amongst other suggestions) and none of the suggestions resolved the issue. My suspicion is that something in a relatively recent update of firefox has issues with my php based code. I do not use a "web tool" but write the source myself. I started writing websites with html decades ago and got the bug to use php years back.

If anyone has the interest (or curiosity) to look at the website in firefox and edge and my source code and see if they see the issue I would be glad provide the link to my website.

When I try to open Facebook , I get the following message Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.facebook.com.

If that address is correct, here are three other things you can try:

   Try again later.
   Check your network connection.
   If you are connected but behind a firewall, check that Firefox has permission to access the Web.

On the rumble website, videos are slow to load (10-17 sec) when I'm logged in. If I log out, videos will load instantaneously. At first i though this was a rumble.com issue but then tested with latest version of chrome MS Edge the issue doesn't happen.

Hello, I'm running Firefox 78 on fresh Debian Stable installation and I cannot access certain websites. I followed step-by-step the instructions by Mozilla Support found here, with no result. Of course, I tried completely uninstalling and reinstalling Firefox, renaming .mozilla folder to create a new settings folder, deleting .cache/mozilla etc. I use no proxy, and I can visit all those certain websites form other browsers of this installation. And I'm looking for a solution for more than 2 weeks now. Any help is welcome!
