I've had this for a few years now and no longer blocking FB from tracking you across you web browser

excelente herramienta

Currently breaks Threads.com. Impossible to access the site with this addon enabled. Confirmed this problem is affecting other people who use Firefox and this addon as well.

Extremely annoying behavior to auto-close your tab with all its history as soon as you click a Facebook link (or Instagram). You try to go back to search results or where you were before you went and you can't. It makes this entirely unusable.

⭐️⭐️⭐️⭐️⭐️ Facebook Container – Keep Facebook’s Tracking in Check

Facebook Container is an essential Firefox extension for anyone who uses Facebook but wants to limit its tracking powers. It isolates Facebook in its own browser container, preventing it from following you across other websites. This helps protect your privacy without forcing you to give up using the platform.

Pros:
✅ Effective tracking isolation: Prevents Facebook from tracking your activity outside its own site.
✅ Seamless integration: Works automatically in the background with no complex setup required.
✅ Boosts privacy: Keeps your personal data from leaking to Facebook when visiting external sites.
✅ Simple and lightweight: No noticeable impact on Firefox performance.
✅ Made by Mozilla: Developed by Firefox itself, ensuring reliability and trustworthiness.

Cons:
❌ Facebook-only isolation: It doesn’t block tracking from other services (you’ll need extra tools for that).
❌ Limited functionality on multi-account setups: If you use multiple Facebook accounts, switching between them can be clunky.

💡 Overall, Facebook Container is a fantastic privacy tool for Firefox users who want to enjoy Facebook without being stalked across the web. It’s easy to use, highly effective, and a must-have for privacy-conscious users. Highly recommended!
