I do the same. Tangentially, I find Firefox's address bar autocomplete to be far superior to Chrome's (better partial/fuzzy matching and combination matches across URL and page titles). A bit ironic given one is the product of a search company.
"Substring matching for Autofill suggestions" chrome://flags/#enable-suggestions-with-substring-match
For the address bar it already does substring for me pretty well so I can't comment on that, sorry about that.
