So, I was cleaning up my Firefox bookmarks, thinking the recent bookmarks were symbolic/relational bookmarks. If you delete a program shortcut (which is just a relational link to the program), it doesn't delete the program. Thinking the same principle applied to the Recently Bookmarked folder, I deleted them all. And all my bookmarks.
Well, at least it gave me motivation to go through my feeds which Firefox checks every x hours (I'm not sure how often it is set to check. Maybe every 4 hours.) rendering Firefox useless for like 10 seconds.
(No, it's not a long time. But it seems longer when it is at an inopportune time.)
