I was browsing Internet, gathering info about boot unlock on my Redmi device and all of the sudden, all pages stopped loading. I checked my router settings, cabels, connectors - all was fine. Then I checked ping on terminal and turned out I had connection, firefox was causing the trouble. It turned out, that I reached limit at this POS extension cut me off entirely, without warning! OK, I get it - I reached some limit, fine - give me VPNless connection back, don't cut me off! Worst experience ever so far
