For me i am careful not to trust to many addons. Several addons have "turned against the user".
I trust gorhill and ublock origin.
I only install verified by Firefox. Disable when not needed anymore.
Besides that i think
Multu account containers
cookieautodelete
Bitwarden
Treestyle tab
I also use vimium although it pains me or had access to everything, and it's not verified. So it only runs in nonessential windows.

For better multi-account container support, you might want to look at Sidebery instead of Tree Style Tab.
Sideberry didn't workout for me. The groups feature didn't work as expected / wanted.
