! Title: Mozilla Blocker - Adblock & DNS Blocklist
! 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 account is blocked. Mozilla download cdn and archive is also blocked.
!              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.
!
!              A Mozilla Trivia: Not Even Ublock Origin is allowed to detect and filter google trackers mozilla uses on their website - Mozilla add-ons.
!              Yes, Most of the Mozilla websites including the add-ons site have Google analytivcs like google-analytics.com and googletagmanager.com. You can check with any non-mozilla browsers, wireshark or dns filterer.  
!              This is due to Mozilla's policy forced onto extension developers, which should tell you Mozilla's privacy stance as an organization.
