# Title: Mozilla Blocker - DNSMasq Filter
# Description: This blocklist aims to block almost all traffic to "Mozilla: Not a Browser/Tech Company - A Political, AI, Data Collection and Advertisement Organization".
#              Mozilla accounts are blocked, mozilla download cdn is blocked. Use forks, otherwise get firefox from trusted sources like trusted stores and package repositories.
#              Just avoid official firefox altogether and use other forks like Librewolf, Floorp, Zen Browser etc.
#              Only addons urls are not blocked so that extensions can be installed from Mozilla Add-ons.
#              Use with a network/systemwide blocker. Adguard Home and Pi-hole for DNS blocking and Zen Privacy Guard from github in windows/linux.
#              Using this blocklist in an adblocker inside mozilla firefox browser won't prevent mozilla itself from collecting data from and running experiments on its users.
