See Reply # 1.  Picture is attached that shows settings that work.

Your Settings box above is closed and I/we cannot see your virus/streaming update settings.  Open the Virus Settings box by clicking the "v" on the Settings line. 

What do you see?

Windows 10 Home 64-bit 22H2 Avast Premier Security version 24.1.6099 (build 24.1.88821.762)  UI version 1.0.797
 UI version 1.0.788.  Windows 11 Home 23H2 - Windows 11 Pro 23H2 Avast Premier Security version 24.2.6105 (build 24.1.8918.827) UI version 1.0.801

Will not be popular with others here, but I found that disabling the web shield will eliminate the problem.  Which would indicate that the statement:  " Firefox Tech stated that Avast is meddling with encrypted connections. The latest version of Firefox (Version 61) introduced a better security protocol TLS 1.3 but Avast cannot cope with it yet." from the previous post/thread is correct.  Not recommending this as fix, just pointing out what I found.

It's Firefox Update 61, they included TLS 1.3 and Avast still uses TLS 1.2 ! See https://www.ghacks.net/2018/06/27/firefox-61-fix-secure-connection-failed/

Deactivate "HTTPS-Scanning" in "Avast Settings" -> "Web Shield" will fix the Problem!

Hi, we are working on a fix, will be released later today.

As a workaround, you can temporarily disable TLS1.3 in firefox settings.

1. In the address bar enter about:config
2. Search or scroll to security.tls.version.max
3. Change the value to 3

Done.

This will limit the TLS version to 1.2, the default for Firefox previous version and other browsers at this moment. I'll update here when an Avast fix is ready. Undoig this configuration change is easy as well, just follow the same steps and change the value back to 4.
