Focus on search field when opening extension

[msp1982dk]

It would be cool if the search field was focused when the extension is opened.
Then we could search without having to click the field.

I'm using Firefox Developer v57.0b6.

Can confirm this is fixed in Firefox 60.0b3

Autofocus stopped working a few days ago. Chrome 105.0.5195.127, Bitwarden 2022.9.1

Nevermind, there's an open issue about it: #3562
