FIrefox 94.0.1 unable to connect to any website - showing PR_CONNECT_RESET_ERROR

[simon3030]

I’ve downloaded the latest version of Firefox, but it won’t connect to any website, and always shows the error message PR_CONNECT_RESET_ERROR

 

I hear that there is an issue with Firefox & Kaspersky...

I also have Brave & Chrome, neither of which have any issues at all in connecting to the same websites.

Windows 10.

10.0.19043  21H1.

Hi @simon3030 , 

Please reinstall the Kaspersky product without keeping the settings. Restart PC, install Kaspersky anew, will the issue persist?

Just done as you suggested, all now works fine.

Thanks for your help.
