Find in page: when pressing cmd+F with selection, copy the selection to the search box

Feature request:

Can we copy the selection to search box if the selection exists and click command + F? That's an user experience improvement that will be frequently used

[GeoffreyParrier]

That would be great 👍

Also:
Escape key should close the search box

To Whom It May Concern:

1. type about:config in new tab
2. search accessibility.typeaheadfind.prefillwithselection
3. enable it
