Bookmarks used to be useful with Opera up until at least version 12 (around the time they killed m2, their JS perf fell behind and chromes process isolation made it overall more stable.) because the entire bookmarked page was indexed. Chrome's poor bookmarking must be intentional to push people to search – other browsers poor bookmarking I can't as easily explain – but some browsers used to have better/more useful interfaces for these kinds of things.
