• uBlock Origin: best adblocker
  • HTTPS Only: Firefox has a new setting where you can force HTTPS. And if it’s not available, you get a warning that you can bypass. I would recommend enabling it by default.
  • Privacy Badger: scramble ads that uBlock missed, find them with heuristics. Privacy Possum is discontinued. May break some websites. Not needed anymore.
  • Consent-O-Matic, Auto Cookie Optout: always say NO to cookie popup related to RGPD. Still debating which one is the most efficient. I currently have all enabled.
  • JSLibCache: store locally JS lib to prevent tracking later if those libs are reused.
  • ClearURLs: remove redirect when you click on a URL

Configure uBlock Origin settings

you may want to check the settings (block remote fonts) and see which lists are used to block ads. You can enable more of them. For example: All the AdGuard filters (especially Français), malware domains. Here are some additional filters that you can add manually.

additional filters

Block by default third-party scripts and frames, and allow manually. This may break some websites (CDN for scripts or frames for youtube) but you can control what will be loaded and run. Disable in the left column, and enable in the right column when needed.
