Hi Mike and welcome,
I'm sure I've seen your very question before but couldn't tell you the specifics why, but, as I remember, the advice was to back up your files to an external device and do a clean install.
I think you can use thebackup tool in the same way for your apps, then do a bookmark/password export for your browser and clean install should be pretty painless, I would guess the end result would be 'cleaner', I'm sure someone more knowledgable will correct me if I'm wrong
