Browser Extensions
The minimum useful set of privacy extensions, in priority order.
| Extension | What it does | Priority |
|---|---|---|
| uBlock Origin | Blocks ads, trackers, malware domains. The most effective content blocker available. Enable the full list of filter lists in settings. | Essential |
| Firefox Multi-Account Containers | Isolates websites in separate containers — Facebook in one, Google in another, so they cannot track you across sites. | Highly recommended |
| LocalCDN / Decentraleyes | Serves common JavaScript libraries (jQuery, Bootstrap) locally, preventing tracking via CDN requests. | Recommended |
| Cookie AutoDelete | Automatically deletes cookies from sites when you close their tab. | Recommended |
| Privacy Badger | Learns and blocks invisible trackers. Complements uBlock Origin rather than replacing it. | Optional |
