When I try to search for something on Google using Firefox, I keep getting the message "cloudflare web-find.net has expired."

What is this and how do I get rid of it?

Apparently, I need to switch to Chrome, because I don't get it there!

Dear Mozilla Support, I would like to ask about Firefox's plans regarding the recent changes affecting SSL/TLS certificates for websites hosted in Russia. As you may know, several international Certificate Authorities have announced that they will revoke or stop issuing trusted certificates for Russian domains. This may cause many legitimate websites to become inaccessible in browsers because their certificates are no longer trusted by the default root store. I understand that Mozilla places a strong emphasis on web security and maintaining a trusted certificate ecosystem. However, I would like to know whether Mozilla has considered any technical solution or mitigation for users who may need to access these websites. For example:

• Is Mozilla planning to provide any workaround or optional feature that would allow users to continue accessing such websites safely?
• Will Firefox receive any updates or patches related to this situation?
• Is the current recommendation simply to manually install additional trusted root certificates, or is there another supported approach?

I am  interested in understanding whether there are any official plans or recommendations for users affected by these certificate changes.

Thank you for your time and for your work on Firefox.

Kind regards, Mikhail M.

12 hours ago Firefox stopped working .No reason ; no changes just the following message including access to this site.So now I have to access with edge . Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

My university website (brightspace) is blocked by "Warning: Potential Security Risk Ahead" and clicking advance does not allow me to continue. I was using brightspace when it suddenly became blocked and I have received errors stating it was an HSTS error to now an expired certificate. I have tried to restart Firefox and clearing the website from my history and clearing cache, but nothing worked so far. Accessing this website has only been an issue on my Firefox on my laptop. The website's servers is not having issues, my other devices can access it flawlessly, and using other web browsers on my laptop does not cause any issues. I would like not to switch my browser, so any help to accessing this website would be greatly appreciated

This is the message I get:

Secure Connection Failed An error occurred during a connection to www.gyroscopereview.com. SSL received a record that exceeded the maximum permissible length.

Because other users (including people who use Firefox) are able to reach this site with no problem, I hope someone can tell me what the issue might be. Thanks
