multiple issues displaying websites (certificates, agduard, sec err etc)
Hi there, i got different firefox issues displaying websites. my configuration: firefox 117.0 (64bit) cleaned 5 minutes ago addons deinstalled (all) kaspersky firewall deactivated fresh start on different sites an ad guard site pops up telling me protection for children when relaoding F5 site it tells certificate is not safe after reloading whit shift+f5 it tells site is not reachable
if i open the same website on chrome on the same laptop everything works fine. there are days when these errors do not occur. on other days it is simply impossible to surf the net. i do not have installed ad blockers or even adguard. but adguard website shows up. we got an avm fritzbox 7590ax to access fibre 500mbit. it seems firefox is not able to interact with something. maybe provider netcologne?
i treid everything to get these website going but nothing worked. and it is only firefox. chrome works. opera too. edge okay.... :-)
any suggestion where to start find out where this adguard websites comes from? any idea why firefox got so many security issues with just normal websites?
best regards wally

Kaspersky can cause performance issues if you have "Inject script into web traffic to interact with web pages" enabled and don't have the companion browser extension installed.
Do a full system scan for malware with something like Malwarebytes to make sure it is clean.
