While this is an incredibly great app for granular control, it is the OPPOSITE of its "with no loss of functionality" mission. This is the #1 go-to source of browser errors that I am constantly troubleshooting and it takes HOURS of time sifting to figure out what to tweak because it provides no help when it breaks something (like a search box)--you just have to go on a lengthy trial and error quest one by one to figure out which of 30 sites to trust to get a search bar working and by that time I don't remember what I was going to search for. So you end up just globally trusting everything and that defeats the whole purpose.
