I wish to add an exception to an address which I host locally. I've explored many options which didn't work such as: Adding HTTPS-Only Exception Disabling certain security features

In this case I accessed my Acer account and clicked on my notebook. I then got the screen shown in the image. I could access the page with Opera, Chrome, and Edge.

This is happening a lot, and is rendering Firefox unusable as my default browser.

www.sejda.com,Your Computer Clock is Wrong Your computer thinks it is Jul 11, 2026, which prevents Firefox from connecting

I'm trying to access livingshield.org? When I try to access this website, I keep receiving secured connection failed. I need to access this website to register for courses

All of a sudden almost every site I try to enter comes up with "Secure Connection Failed". This started happening on Friday, July 10th for the first time. I've read almost every article in the Firefox's community forums and tried multiple actions and nothing stops this. I don't know why this all of a sudden when it never did this before. I hope someone can tell me how to stop this from happening].

After updating Firefox to a newer version, some websites that previously worked on the older version started displaying **"Page Not Secure"** and **"Page Expired"** errors, preventing them from loading correctly.

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

When I try to log in Hollywoodbets.net the page doesn’t want to open it says it is protected by WE1 certification so how I change that

I have a home server 192.168.0.240 in my local network. Firefox does not let me in to my own pages. On the address line appears text "Not secure",

I have found no way to get in. I have there REALLY IMPORTANT TOOLS AND MATERIAL and I need it AS SOON AS POSSIBLE !!!!

This is really stupid. I have used these pages until this weekend. I have had this problem many years, but always found some way to make it work. I am NOT going to buy a certificate to every server I have home. it costs $$$$.

Hello, I am facing a very strange and frustrating issue with my website https://biografieblick.de/, and it is only happening on the firefox browser other browsers like chrome, edge or safari are loading the site perfectly fine. The Issue is it occurs occasionally, Yeahh IDK why. When I try to visit my site, Firefox gets stuck on a screen that says "Checking if the site connection is secure" and it looks like an loop sometimes.

This looks exactly like a cloudflare turnstile loop but I am NOT using cloudflare. I have double checked my DNS records and explicitly confirmed this with my web hosting provider. This block only triggers when using firefox.

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!

Loading website for BacaPoa.frontsteps.com does not work, now fails ("not secured") . This is business site I have for years.? [windows 11] Is the a bypass or override I can do? JR

Hello,

Since this morning, I haven't been able to access Bsky on my laptop because of a supposed HSTS risk, which means I can't add an exception to visit it. I use Firefox on my Android and going to the mobile version of the website lets me in no problem, so I assume there's an issue with my laptop.

I'd usually wait a few days and let it solve itself but just in case it's something on my end, I'd like to solve it! I'm on 151.0.4 (64-bit), don't use a VPN or an anti-virus, I have a couple of privacy add-ons but they've been here forever and they've never caused a fuss. I can post a screenshot of the error code and the certificate it sends me if it's any help.

I'd appreciate any pointers! Thanks!

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.
