What mac system files are shared by most web browsers?
There is a particular discussion board on a website that I frequent. I use Brave browser, mostly. On my MacBook Pro, I recently got a message saying I was banned, (I'm not). I also had this problem on my de-googled Android a couple of months ago and solved it by installing a different browser. I had first tried deleting and reinstalling Brave, but that didn't work.
Now, on my MacBook Pro, I got the same message using Brave browser. I then tried Safari, FireFox, Dissenter, and Chrome. I get the banned message on all of them. I can access the message board through my iMac, using Brave.
I'm assuming there is some file or files that all the browsers on my MacBook Pro use to log into the website that has gotten corrupt, either accidentally or maliciously.
Does anyone have an idea of how to fix this?
BTW, I'm not getting similar errors on other sites and I'm in contact with the site admin.
