"Firefox Suggest" string appears when search matches a bookmark

Our support has received an email from a confused users who thought this meant Mullvad Browser somehow could access Firefox.

This issue is the same as tor-browser#41691 (closed)

I don't see any value for having "Mullvad Browser Suggest" or any similar string here, as it's obviously a suggestion.

I'd like to follow @cypherphunks1 suggestion in the aforementioned TB issue and change browser.urlbar.groupLabels.enabled to false by default.
