Today Kaspersky AntiVirus 126.96.36.1991e updated as usual, then a Windows 10 pro update (21H1 I think, though I already had 21H2) installed, and now I can’t connect to any websites on Firefox v.91.0. It works on Microsoft Edge fine. With Firefox I just get the following message for any website I try:
Secure Connection Failed
An error occurred during a connection to click.kaspersky.com. PR_CONNECT_RESET_ERROR
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.
Any ideas how to fix this please? I’ve tried reinstalling Firefox and Kaspersky AV to no avail, tried clearing browser cache and resetting it, reset modem and router and a few others things I don’t remember. If I disable Kaspersky, then Firefox works properly.
Thanks if anyone can help.
