Diễn đàn hỗ trợ Firefox

Hello, I've got two profiles, 'Home' and 'Work'. I run two Firefox windows with these profiles. Now, I want to open a link from another application, like Slack or terminal, and want it to be opened in some predictable Firefox window. Now it depends, probably, on which Firefox window I opened last. So I want to be able to select in which window the links should be opened: I see it as marking a window as the default one. Note, that I don't want to set a default account, as there's no default account for me, I always choose which account to use when opening Firefox.

Thanks.

The topic says it all. How do I prevent Firefox from shifting my typing from the search field to the address bar?

I try to type a search into the field on my homepage but the cursor gets shunted up to the address bar and I can't find a setting turn it off. I would prefer my typing to stay where I place the cursor with a click rather than being shunted off somewhere else on the screen.
