Feature request: Sort by "frecency" #48

Closed Kantfnas closed 2 years ago

Kantfnas commented 7 years ago

Firefox has this excellent ranking system called "frecency" (portmanteau of frequency and recency), which it uses to rank suggestions when you type in the address bar. I think this would be a great way to order bookmarks as well! The algorithm is all there and the ranking is continuously updated in the moz_places table.

Some information on the frecency algorithm used here.

Would this be the same as "Sort by Most Recent Visit" or "Sort by Visit Count" using the Firefox sort feature?

Sorry about my delayed answer. The notification was filtered out somehow. No, it would not. "Most recent visit" sorts by the latest date of visit (column last_visit_date), whereas "Sort by visit count" sorts by, well, the sheer count of visits (column visit_count). The column "frecency" contains a metric which is a clever combination of the two, which decreases slowly if, for example, there is a place you used to visit often but don't anymore, and hence has a high visit_count but isn't very relevant. As far as I can see, there is no such manual sorting feature in Firefox, but the frecency rather works "behind the scenes", adding relevance to each item in the search/address bar.

Sorry for the long delay. Unfortunately, Firefox does not provide this information to add-ons. Based on the following bug report, I don't think they ever will: https://bugzilla.mozilla.org/show_bug.cgi?id=411591 Therefore, I'm going to close this issue.
