Are there any analogues of the omnibox in Firefox?

Question

Google Chrome

Chrome started eating too much memory and had to switch to Mozilla.
Everything about her is perfect, except for one. Previously, in the address bar, you could write yandex.ru or, for example, ozon.ru, press the spacebar and then immediately enter a search query on the specified site. Plus, I set up aliases for Google Translate and a couple of other services... Mozilla doesn't have any of that. Maybe there are some extensions or hidden functions to do this?

Answer 1

Everything is the same in Mozilla
Settings> Search> in the list of search engines, specify the alias.

Answer 2

FireFox has a separate search field adjacent to the address bar. Enter a search query and a menu of connected search engines drops out - click on the selected search engine in it:
Cmd + L - focus on the address input field; Cmd + K - focus on the search field.
