Diễn đàn hỗ trợ Firefox

Greetings all, my trusty Firefox stopped working. Error Code PR_Connect_reset_error. Other browsers work fine. I have windows 10 with the latest updates and use Kaspersky Internet Security 21.3.10.391 (m). I have paused Kaspersky, uninstalled then reinstalled Firefox 3 times. I have cleared all Firefox cookies and caches a number of times. On my 2nd Firefox reinstallation Firefox worked ok for a couple of times then stopped again with the same error code. Please note that I am not very familiar with computer stuff so any suggestions need baby steps. Many thanks.

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.

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.

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:8080.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

HOW TO CONNECT

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

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.

1, provide phone support....which i am willing to pay for.

2. fix it -- remove the problem via an update

3. A new computer....and I still get this "Application error: a client-side exception has occurred (see the browser console for more information)." WHY ? Of course, GREAT that Mozilla never has real people to staff tech support.

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?

Why does Firefox intermittently fail to connect to the Newsmax website? I get a Secure Connection Failed message. It happens only occasionally, but enough to be an annoyance. What's the problem and how do I resolve it?

The error SEC_ERROR_REVOKED_CERTIFICATE means that the website's SSL/TLS certificate has been revoked by the certificate authority (CA). This prevents secure connections because the certificate is no longer trusted.
