For some reason, whenever I log into websites like Twitter or something like Aritzia, it does not register that I have logged on and instead either stalls once I enter my information and then doesn't actually log me in or it just doesn't log me in in the first place. Below is the image I get when I try to log into twitter - the black box that has the login info remains and the entire page is no longer useable. When I refresh, it is like I never logged in in the first place.

I cleared cookies, my cache, I did the about:serviceworkers thing and unregistered the site. What else can I do? I can log in on chrome, plus whenever I try to log in I get a message on twitter that someone's trying to log in so I know its not an issue with my account
