Thanks for the Better History one. Firefox has such a garbage history function.

Firefox translations (local-only website translation)

Firefox translations is good, but i'd recommend linguist instead, its still on-device (if you switch to the local engine in its settings), but is more feature rich, and i've found it to provide higher quality translations.

Buster Captcha Solver

Theres also privacy pass for cloudfare's captchas

Nitter Redirect

I'd use libredirect instead, achieves the same purpose but also works with a tonne of other services as well and not just twitter -> nitter redirects, but also reddit -> libreddit, youtube -> piped, etc.

Facebook Container & Multi-Account Container

The only usecase for containers are multiple accounts, not privacy/security, fission's sandboxing already takes care of that on firefox.

You have a huge number of addons though, i'd try to limit the number of installed addons unless it provides a purpose which is absolutely essential, can't most of these addons be replaced with userscripts in violentmonkey? At least that way it's more confined, in that it has privileges over a specific website rather than the entire browser. Know that every addon is a risk, even if the addon itself isn't malicious, it could have a security vulnerability to be exploited.
