uBlock Origin, Firefox Multi-Account Containers, Temporary Containers, Containerise, and Tree Style Tabs for me. I also quite like Tab Session Manager, and get a decent amount of use out of QR Code Generator.
uBlock Origin is an ad blocker, and script blocker, with per-site rules. I use it in "Advanced User" mode.
Multi-Account Containers allows isolating sites to containers, all cookies, local storage, etc, are kept within that container only (but all addons work across all containers). So my HN container saves my HN login, my Stackexchange container saves my stackexchange login, etc.
Temporary containers makes sites that aren't assigned to a permanent container get assigned to a temporary container that gets deleted shortly after they're closed. So anything that doesn't have a permanent assignment gets something akin to a Private Browsing tab.
Containerize allows wildcard matching for domains to permanent containers. So sites with logins that have a bunch of subdomains & redirects can match all of them to the same container. EG *.jetbrains.com opens in a container for Jetbrains, so their redirect-to-login flow works.
Tree-style tabs provides better organization of things I'm working on than flat tabs without a hierarchy.
Tab Session Manager lets me save and load entire sessions of tabs at once, or just single windows from a session, and give those sessions names.
QR Code Generator is handy for exactly what the name says.
Containers isolate more than just cookies, they isolate all local storage. So each container acts like 3rd-party cookies are enabled, they get saved, everything works even when silly website authors use 3rd-party services for authenticaton, etc. But it's all isolated, so the sites in one container don't see any of the storage in another.
