Was extremely useful, but as of early May longer seems to work at all.

Leaving this for people who have issues with Threads. Go to threads.com, and then click the add-on in your toolbar or add-on dropdown, and click "Allow Site in Facebook Container" and that will solve the issue. Meta changed their domain to ".com" and until they update it to add that new domain, it's blocking the website from loading.

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.

目前會導致THREADS無法使用

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.
