How to search a specific value in firefox's "about:conifg"?

[Jacob]

Basically, I'm trying to make it so that whenever I search in my address bar, it searches in google and not some adware thing my dad installed. Is there any way to search a VALUE and NOT the preference name.

adware usually installed as plugin/addon and there are some cases when it installed along as .exe
and causing the browser to forcefully using the adware search (even if you change it to another one manually is useless)

answer to your question:
in the search bar below type 'search' and look for 'browser.search.defaultenginename'
and change the string value to 'Google'
