Error shows on: https://www.privacytools.io/ Also on google.hr sometimes but after one refresh it loads properly. I have problem with downloading add-ons also, it won't install them (some error also). YouTube videos don't load and pictures don't load. I've tried restarting Firefox to default settings, reinstalling, deleting all Firefox files and registry keys but it's always the same.

P.S. Can't upload screenshots for some reason, here's a link:

Thank you so much! That seems to fix all the problems. P.S. Forgot to mention I have ESET NOD32 AV.
