Once every few months I try to clear out a bunch. The last time was probably close to 150. Some are reminders, I really should do it a better way, but its really easy to forget about something in a bookmark and sometimes I just want to remember to come back to some silly comic and having it sometimes in view is enough. Honestly yea there is a chance loosing the tabs would cause me to tap out. For unloaded tabs they aren't in history and some of them have been there for... years. It would really bother me to not know what was lost.
