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?

NOTE - I am using Firefox on my PC which is working fine. Issue is with my laptop Firefox.

Firefox was working fine, on my laptop and PC, until about 3 days ago. Started getting Tried to download various versions of Firefox. I am using Firefox on my PC with the same exact settings, network, Win 11 and Antivirus as my laptop. Firefox, version 128.6.0esr (64-bit) works fine on my PC, but does NOT on my laptop. I uninstalled FF and reinstalled it, changes Firewall to Windows on the laptop from my AV, NOTHING. Driving me crazy. HELP please.

I have never had a problem opening my email client before in Firefox, but now after the last time I started my computer I get this message when I try to open my email client (Shaw Webmail):

400 Bad Request Request Header Or Cookie Too Large nginx/1.24.0

Oddly though, it will open if I go into the Incognito window. Why is this happening and how can I fix it so I don't have to constantly into Incognito mode to access it?

Hello, when I browse the internet, randomly the certificates seem to break as I get https certificates for sites that seem to have nothing to do with the sites that i intend to visit. Then errors like the ones in the screenshots appear. Usually reloading the website helps and then the certificate displayed seems to be correct. I did make sure to upgrade to the latest version of FF (136.0) and I did clear all cookies, but it didnt help. I do not really have any idea where to start searching or what might cause this, tia for help. kind regards Thomas

The error SEC_ERROR_REVOKED_CERTIFICATE means that the website's SSL/TLS certificate has been revoked by the certificate authority (CA).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.

Dear Sir or Madam: I seem to have a compatibility problem with my firefox browser. Not always, but often, I get a 502 error when I try to log in to my bank account. After contacting my bank, I found out that their program is not compatible with firefox and that I should use Google, which choose to avoid. Is there a patch or fix that can get rid of the 502 error and allow me to continue using Firefox, which I have used for almost twenty years. I don't want to switch to Google, EVER! Please let me know what options I might Have.

Respectivly, Louis Osip
