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.

Hi!

Since most content is in English and search engines always link to the English version, I usually browse the english version of mozilla pages. But here on support in particular I have to contend with the pathetic date format where you can't tell which is day or month or year. So why can't I find a way to set the date format. Even the majority of tiny websites/forums have an option to specify the date format.

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 :)

For a couple months now I have not been able to paste anything on Facebook via Firefox. I can use Explorer, Chrome and can paste anywhere else just fine. When I paste on Facebook messenger, the chat window closes and I have to refresh Facebook to even be able to see my messages again. Otherwise, I click on it and nothing happens. When I try to paste a post on my wall, it I get a "Something isn't working. This may be because of a technical error we're working to fix." (I just copied and pasted that here no problem) Tried clearing history/cookies/cache. Help?

The last Firefox updates have suddenly created havoc. None, absolutely none of the websites that I frequently visit will have my login information saved even though when I view logins in the settings mode, they are all listed there with the correct passwords. I am not technical and would sincerely appreciate a tutorial of some kind as to how to correct this egregious oversite on behalf of the Mozilla team.

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?

I've been having an interesting problem with Firefox for the past couple of months regarding only Soundcloud, where after the first visit to the website it won't load, giving a generic "Sorry! Something went wrong" screen. Firefox will continue to not load the site correctly until I clear the cookies and the cache, which works but only for one visit, and as soon as I close the tab and open soundcloud again or refresh the tab the problem comes back. I have disabled all of my extensions as well as enhanced tracking protection when testing. A firefox refresh also did not solve the problem. The only way I can get the site to behave normally is when using private browsing.

The console is filled with errors regarding javascript files (source URI is not allowed in this document).

Thanks

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 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?

Hello,

Today I allowed FF to upgrade to 92.0 (64-bit). I do a lot of work at Ancestry.com and notice that every time I open or refresh a page I get a pop-up message that says "It looks like you have local storage disabled. While you'll still be able to use the site, you may notice that pages load more slowly. Fix the issue."

I followed the Fix the issue link. It took me to a page that said I needed to allow cookies. I do have the cookies enabled.

Any Idea how to fix this?

Thank you in advance for your help!!
