Pin domains to container tabs

[n3wjack]

I use container tabs to separate banking, work and privacy invasive sites like Facebook.

It would be great if there would be a way to pin a URL to open in a container tab.

For example, if I click a Facebook link anywhere, it would automatically open that page in the Facebook container tab, instead of a regular new tab.

The same when typing a URL (with history completion) in the address bar, for a work URL, etc.

EDIT: just found out this feature actually exists https://support.mozilla.org/en-US/questions/1319312#answer-1379940
