Wtf is wrong with you

Is “literally” an adverb? I always though that adverbs were like adjectives but used for verbs (actions). Like “quickly” or “slowly”. Where is the action in a sentence like “It’s literally the same browser”? Is it an adverb for the “is” (to be) auxiliary verb? srry english not my first language

The word is actually correct in this case, though. Chromium is, in every way that matters, literally (as in exactly, completely, utterly, fully, in actuality, totally) the same as Chrome.
