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 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.

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

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??

What is the problem with Firefox? Is it s dangerous un-secure webpage now? Can Firefox still be trusted?

Hardly any webpages load anymore. Constantly getting error message. Do not get those messages with Microsoft Edge or Chrome. Can't search for financial institutions, car part stores or hardly anything anymore. I don't believe Firefox can be trusted anymore. Is their a Data Breech in progress with them? I am tired of seeing:

What is the problem? I have written about this before and NEVER get a response. Is it really time to just switch browsers? I have noticed when Firefox won't work Microsoft Edge and Chrome works just fine. What is the deal here?

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

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.

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.

Hi.

Can't access router gateway since last week

Gives error: Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

Gateway is http only, I can access it fine via Edge and Safari iOS

I tried disabling https-only though it used to work fine before with a saved exception.

Made sure Win10 firewall allows Firefox for private/public

Followed the help link and deleted the previous certificate from the certificate manager, but I can't find anything relevant under the servers tab

I'm at a loss. Many thanks in advance.

For the past few months, I've been getting this error and been searching for possible solutions. None of which have worked. I am also not using Kaspersky AV. With this, I'm asking if there's anything else I can do.

Here are the solutions I've tried: 1. Troubleshoot mode / disabling add ons 2. New profile 3. Clearing cache / cookies / dns 4. Changing "DNS over HTTPS" & proxy settings 5. Disabling firewall / AV / VPN 6. Chrome loads the site but I do not want to resort to this. Using developer mode browser does not work either for firefox.

I have just re-installed MW due to probs using the original one, but now I cannot enter my registration code,(life time) there is no where to do so it seems,have looked everywhere?

When I try to read my webmail I get this:

Secure Connection Failed An error occurred during a (https) connection to www.nebula.fi. Peer’s Certificate has been revoked. Error code: SEC_ERROR_REVOKED_CERTIFICATE

The same address www.nebula.fi works fine in Edge browser, which claims: Connection is secure. This site has a valid certificate, issued by a trusted authority.

I would prefer using Firefox. Is it somehow possible?

Hi, I am working on an extension which fetches my google calendar events and shows them nicely as graphs and summarizes the events. I need a CLIENT_ID in for getting an access token from google (OAuth2). I got one from my google cloud console but I don't think I should push that to the add-ons site.

I am quite new to this javascript/browser world and don't know where to go from here. It would be great if people can just download my add-on and just use it without providing a client ID and zipping it themselves. I asked this question on stack overflow and they marked it as off-topic :_).

So far I couldn't find any information related to this on the web.
