'''the problem''' Recently in the last 2 weeks Firefox suddenly started giving errors whenever I went to any website (including any search engine). Except for my school portal that worked find. '''what I've tried to fix it''' I've tried messing with the settings and l've reinstalled Firefox three times but it didn't really help at all. '''additional information''' * If I use any other browser like safari then everything works fine. * Also just before the problem started I installed the Cloudflare 1.1.1.1 app, but I completely deleted it and the problem still persisted. * The problem only happens at school, at home in my home network everything works fine *I used Betterfox although I have tried it without Betterfox installed * The first time reinstalled Firefox and Betterfox I also signed up for Nextdns and set that un in system settings it still didn't work so I tried to remove it but I'm not certain it was removed. * Just this morning I logged into Firefox in my school and it worked but then I reinstalled Firefox again and it broke. I can't remember why I decided to do that. * When I use a vpn it seams to work but I would rather be able to connect to the internet without a vpn.
