good to have someone swinging away at keeping live bookmarks alive in firefox. so far, it looks the part, but there's one big problem.

the bandwidth + cpu overload for large numbers of feeds is the main issue. set it lower than once every 20 or 30 minutes and you'll regret it. tried 1 minute as an experiment, firefox locked up and i had to kill it in task manager. definitely needs an option to limit the number of threads that update concurrently and/or an automatic limiter that caps it at 4 or 5 threads at a time.

feedbro has such an option, but for those who are looking for simple pre-v64 dropdown menu style feeds, reader add-ons just don't cut it.
