Mozilla's issue, as the Chrome is working perfect.

Certificate Dropa Sep 20, 2023, 8:55:35 AM

You don't indicate what or where this certificate is coming from for any forum user to know what is happening or why it's not being recognized by the browser.

I started getting screen flashes and then identifying pop up windows that go to adform dot com addresses, that are blocked on my computer so nothing other than a error shows up. Its annoying and random. I have checked security page and it says Block pop-up windows and this is blocked. Two exemptions are there which are acceptable. I have run virus checks on Bitdefender and Malwarebytes (Latest versions update) nothing is reported. - What is causing this and how do I stop it? After opening up the hidden window that flashes it tries different pages all fail then eventually the pop up window closes on its own.

Using latest version of Firefox browser 117.0.1 (64 bit) Don't get the pop ups on Google Chrome.

HTTP/3 doesn't work regardless of my config:

network.http.http3.enable = true network.dns.httpssvc.http3_fast_fallback_timeout = 0 network.http.http3.priority = true

and https://cloudflare-quic.com/ and console still show I'm using HTTP/2. Tried on Firefox nightly and chromium (chromium works fine but firefox doesn't.)

Something in the last few Firefox updates is now preventing me from logging into the admin interface of my home router (Sonicwall TZ570) and wifi access point controller (Unify Cloud Key). I have had these devices for several years and Firefox has always allowed me to make an exception and connect to the "unsecure device. Microsoft Edge is giving me the same problem which started about the same time a couple of weeks ago. I am on the latest version of Windows 10 64bit and Firefox is up to date. The Brave browser still works as it should (see first screenshot), but Firefox gives me the "we could not verify the certificate: reason = untrusted" error with no way around it (see second screenshot). I do not have HTTPS Only Mode enabled (see last screenshot) and I don't see any other security setting that should affect this.

This is my home, not a business and I do not have a domain nor a SSL certificate and I should not need one.

Any help will be greatly appreciated. Thanks!
