This idea is related to the plugin: Multi-Account Containers
https://github.com/mozilla/multi-account-containers
I wanted to create an issue there, but it would lead me here. So here's my idea:
I use lots of different containers and I always use the search functionality to use the desired container.
Therefor it would be very useful if after clicking on the plugin icon and opening the modal, if my text cursor would automatically jump to the search bar, to be able to use this feature with fewer mouse clicks, making it more accessible at the same time.
(Add on: If I could use a shortcut to open this modal and then select the container via keyboard, that would even be better for my productivity)
