How can I restrict which bookmarks Firefox includes in the list of url's that are suggested in the location bar? I have many bookmarks that I rarely use, that on the one hand I don't want to delete because I may need them in the future, but that on the other hand I don't want being used routinely for location bar suggestions. Is there a way to tag which bookmarks Firefox should consider when making suggestions? (I realize one way to try to do this would be to categorize bookmarks into separate Firefox profiles, but I would have to give up too much flexibility to do that. I also prefer to clear my cache frequently, and I don't want the location bar suggestions based on usage frequency/history--I have 'use history' de-selected.) Firefox 43.0, Mac OS X El Capitan (10.11) (I tried a more recent Firefox release a few weeks back, but it was too buggy, so had to downgrade back to 43.0)
