Secure Connection Failed An error occurred during a connection to (Firefox and ALL sites) PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR Help advises 'Failed to check for updates' Problem arose on upgrade to Firefox 138 Tried restart, computer reboot and reinstallation

I am not sufficiently computer literate to understand supposed help and support documents within 'Mozilla Support'

It looks like the end of 20 years of using Firefox ... Google Chrome used to submit this request

I have an issue where I will frequently get the error pictured on random sites. This started happening a few years ago at my previous home with my old computer. It got so annoying that I had to switch to Brave browser for a while. I recently moved to a new residence, I have a new computer, and a different ISP and equipment, so I thought I would give Firefox a try again. To my shock, the issue still occurs exactly the same way at the same rate. I would say it is as frequent as 1 in 5 sites that I visit. If I hit the Try Again button 5 or so times, the site will load. The only thing I can think of that is common to the old computer and the new one is my Firefox account. Could there be something in my settings causing this to happen? I remember that I even tried Librewolf before switching to Brave but the issue occurred there as well. Any assistance or tips would be appreciated, I feel like I am going crazy at this point. xD

I dread the days where FF has an updated version of something for me to install.. because this issue ALWAYS rears its ugly head.

I've been ignoring the updates since Feb and for very good reason because this time (138.01 or whatever) I'm unable to bypass these security certificate expired error codes that say:

"If your clock is already set to the right time, the website is likely misconfigured, and there is nothing you can do to resolve the issue. You can notify the website’s administrator about the problem." I literally was able to access all these sites without issue until I downloaded your must have update. How is this fixed???

Should I just uninstall FF and go back to Brave? I'm so tired of dealing with this as a normal day to day, no coding/tech background, etc. internet user.

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

Starting on October 18, I've had problems accessing most websites. I get security errors such as:

Secure Connection Failed Error code: SSL_ERROR_RX_RECORD_TOO_LONG

Secure Connection Failed Error code: PR_END_OF_FILE_ERROR

This problem occurs only with Firefox. It doesn't happen with Chrome (which I had to use to post here).

A few sites work, but not many.

I tried reinstalling the latest version of Firefox but that didn't make any difference.

Suggestions? Thanks in advance.

Examples of webpages I've entered today that receive an error message are https://leafscape.com & Mint Mobile

Hmm. We’re having trouble finding that site.

We can’t connect to the server at fzttlwrt.r.us-east-1.awstrack.me.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

Trying to search on Firefox is now 70% impossible. Keep getting error code: Secure Connection Failed

"An error occurred during a connection to www.google.com. PR_CONNECT_RESET_ERROR

What is going on with this? I even get this code when I try to search on how to reset ALL settings back to factory default. What can be done??

Hello,

I want to open this URL: https://compatibility.plantronics.com/deskphone Firefox 136.0.1 tells me: SEC_ERROR_REVOKED_CERTIFICATE

The same URL opens in Chrome and shows no sign of a security problem, as far as I can see (Chrome info attached).

What could be the cause? Firefox being to strict or Chrome just too relaxed?

Thanks in advance.
