Facebook Container – Mozilla (opens in new tab)

This, and AFAIK they're still implementing the rest of the API so that all add-ons will be supported (on Android).

it's in stable now too. noscript is a lifesaver on low-end phones.

yes. containerization allows you to segregate your browsing sessions even when necessary page functionality includes code/assets from entities that would use that inclusion to track. think of it as minimizing your surface area. temporary containers in particular are like a fresh session in every tab.

i combine containers with noscript, ublock, and decentraleyes.

Exactly.

My son's school has been using Facebook for most communications. I discussed it with their IT person - they said it was mostly a trade-off between security, privacy, usability, and cost. Most parents didn't care much about privacy, so Facebook won.

It's frustrating for those of us that do care about privacy, but I can see why it's such a difficult decision.

uBlock Origin is also a must-have.
