Hi everyone,

I've got a real curious problem. I'm a student at Berkeley City College. Firefox is my preferred browser. Sometime this semester, I stopped being able to access Google.com or any google subdomain sites like Google Calendar while using Firefox Desktop at school. Here's where it gets really weird. This only happens when I using firefox windows desktop while also being on the school network. If I switch to my phone tether network then I can access Google just fine. If I launch a different browser (that is not Firefox based) like Chrome, it works just fine. I tried accessing google using Waterfox on the campus network and encountered the same problem. I consider myself to be somewhat technically proficient but this is confounding me. How could the sites at a specific domain be blocked only while using a specific browser on a specific network???

Did you try another computer at school? Did you try another account on that same computer? Browser cannot find (smells like DNS issue) google.com.

I had another user with the same issue in Brazil. https://support.mozilla.org/en-US/questions/1552049#answer-1783416
