On: Firefox Multi-Account Containers

[Vinnl]

It's not super-efficient, but it is keyboard accessible: press Ctrl+. to open the Container selection menu, then the down arrow to the Container you want, and Enter to open a new tab in that Container.

[rsync → Vinnl]

Actually, I see that you can press number keys to spawn the container tab you want in that pick-list.

So, you don't need to down-arrow and pick, you can just:

ctrl + . (ctrl + period)

then hit '1' or '2' ...

[Vinnl → rsync]

Well, today I learned - thanks!
