I have bookmarks dating back to probably 2009 or so, from when I was using Firefox up until now. 6 years of bookmarks seems to slow down my address bar as Chrome seems to search through them every time I type to make a suggestion. I like the suggestion feature, but I don't like how it takes up to 10 seconds for Chrome to recognize my keyboard strokes, and we're talking new hardware here.
So beyond Google optimizing the address bar with more aggressive caching, my question is, is there a way to delete old/unused bookmarks in Google Chrome? I see how I can delete all bookmarks or chunks of bookmarks, but not necessarily just the ones I no longer use. Figured there would be an add-on for this but I haven't found one. Any suggestions?
