Kaspersy Suggest To Import Certificate In Thunderbird

[Alebit]

Dear friends..I have a PC with Windows 11 Pro installed and I have been using the Thunderbird email client for a long time to manage my emails.

Specifically, I use an old version of the client...exactly 60.9.1...which I have never updated so as not to lose the many additional addons no longer supported in subsequent versions.

Well...this morning among the "suggestions" that Kaspersky offers me I see one that says: Secure traffic in Thunderbird is not monitored".."to resume monitoring add the certificate manually".

Naturally I went to look for the official Kaspersky instructions to fix the thing ,and in practice I should follow this path Settings > Network and Internet > Advanced Network Settings > Internet Options > Content > Certificates > Trusted Root certification authority... and here, scrolling through the real certificates present, select and download the Kaspersky one.

I refer to what is explained here https://support.kaspersky.it/common/compatibility/14620?cid=234-WIN_21.23#block2

And here's the first question...in what format should I export it? I am offered two options: The first "Binary Coded Der X.509 (.cer)... and the second "Base 64 Coded X.509 (.cer).

I attach two screenshots to explain it.

So in what format should I export it and then re-import it into Thunderbird?

In Thunderbird then following this path Options > Advanced > Certificates > Manage Certificates you would arrive at the section from which you can import the certificate.

In this regard...and finally...I therefore wanted to ask:

Until now Kaspersky (which I have been using for many years) had never suggested this operation to me... why?

Is it necessary to install its certificate in Thunderbird?

In short, what is the purpose of carrying out this operation?

Sorry if I was a little long-winded in writing but I wanted to explain the situation as best as possible.

Thanks in advance to anyone who wants to participate.

Best Regards
