So for instance, I've noticed this happening twice now. Once is from chatango(which is a chat systems on websites where you can watch streams and engage with the community there) which happens when I receive a private message, I open the private message page of chatango and I get the usual connection isn't secure. I've attached screenshot of the message I get as well as my firefox extensions which are ublock origin, privacy badger, decentraleyes and malwarebytes. Now initially you could say, hey that chatango is a sketchy site and it's the issue which is what I assumed at first despite that website being pretty big and used on many many sites. I just encountered the same error again on path of exile official website : www.pathofexile.com (it's a very well known game). I got the error when I got redirected from a build site that's again well known in the poe community. When I clicked on a build I liked it redirected me to the official path of exile website forum section where the guide is. Now if I go to that page directly from the official website I don't get this error but when I'm redirected to it I do. It's similar with the chatango part, I'm on a website talking in the chat and get a dm so I click on the dm icon in the chat which directs me to the official chatango website(to see my dms and I get the connection isn't secure). Now I know for a fact that pathofexile.com is a secure website so what is causing this? How to fix it?(added a screenshot for the issue for path of exile official website as well). Also this doesn't happen on other browsers, obviously I prefer firefox for it's privacy and it being a very good browser overall but this situation is a little annoying so I'd like to fix the issue and be able to access those website normally.
