Firefox v.58.0 blocks all websites. It's time to go back to the Internet Explorer.
Doesn't matter which website, I can't open any o them with the newest version (58.0). I am permanently getting the following warning: "Your connection is not secure" with the error code: "Error code: SEC_ERROR_UNKNOWN_ISSUER". Even to log to your website I had to use the Internet Explorer. What a shame.

I suspect Kaspersky is the problem here not FF since it worked in previous version. I use Defender and Windows Firewall and have no such problems as your describing.

thank you!
Well, below is a response to the weather network web site. The same applies to every of my old and new attempts to open some web page. To be clear, I didn’t touch any setting (like virus protection program – Kaspersky). Firefox has been working perfectly for years. Yesterday I turned off my computer at noon and then turned it on 3 hours later. I tried to open Firefox but immediately I got that “updating message” and few seconds later, when Firefox launched, it couldn’t open my home web page. Again, I haven’t touch any settings on my computer. Any change came with your update. But now even the previous version (57.4) doesn’t work.
Regards, Peter

ok, then please try to set-up kasperksy as it's described in How to troubleshoot security error codes on secure websites
Yes, when I disabled the scanning encrypted connections it started to work. Before Kaspersky scanned encrypted connections upon request from protection components. But it worked with all previous Firefox versions!! So, why are you introducing such changes?
