How many did you try? As I said, after the computer starts, the first few (I don’t know how many) HTTPS sites work: even after several force reloads they don’t show the warning message.
Trying 7 might not be enough. I suggest trying the steps to reproduce in my other post. I am not sure, you are not affected by the bug, until you try those steps, and report, that in all 40 cases you didn’t see the warning message.
Are you using the Japanese version of Avast? Are you on Windows 11?
We are talking about a warning message that can be seen in the Site information popup of Firefox on almost all HTTPS sites. Screenshot and details are in my other post.
