Best Privacy Add-ons for LibreWolf (Windows Edition)
A pragmatic, low‑breakage setup. Start lean, add carefully, test each site. Too many extensions can increase fingerprinting and cause breakage.
How to choose extensions
- Prefer one well‑maintained blocker over many overlapping ones.
- Review requested permissions and changelogs before installing.
- Test sites after enabling an extension; whitelist when necessary.
uBlock Origin baseline
Efficient content blocker with fine control. Start with default lists; add filters only if needed to keep breakage low.
ClearURLs
Removes tracking parameters from URLs to reduce link‑based tracking. May require per‑site exclusions for strict sites.
Cookie AutoDelete
Automatically clears cookies for closed tabs while allowing whitelists for sites that must keep you signed in.
Decentraleyes / LocalCDN
Emulates CDN‑hosted assets locally to reduce third‑party requests. Verify site compatibility and choose one — not both.
HTTPS‑Only (built‑in)
LibreWolf enforces secure connections by default. Keep it enabled unless a legacy site absolutely requires HTTP.
Privacy Badger (optional)
Learns to block trackers automatically. May overlap with uBlock; use either in learning mode or not at all if you prefer manual lists.
Low‑breakage tips
- Use per‑site toggles for media/DRM domains (see DRM & Streaming).
- Avoid stacking many blockers; measure before/after with the same sites.
- Keep extensions updated and remove those you no longer need.
Install the browser first
