Hello,

I’m having trouble accessing sites like outlook mail box. I get error 500 something has gone wrong. I can login fine if I’m using edge or chrome. I noticed other sites I’m not able to login without getting some errors.

I uninstalled Firefox, deleted its files in appdata and in registry. Is there another fix to this? Or is the only solution to move to another browser?

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
