Interesting fact. I have never used an ad/tracker-blocker on any browser on any platform.
I just got sick of the missus telling me that 'Linux kept freezing' and she 'was sick of it'.
Installed Ghostery and guess what, her constant perusal of Daily Mail Online no longer hangs her Firefox session (not the computer, obviously).
I'm not being worthy or patronising here but, as is being borne out by installing those add-ons, my web browsing experience (performance wise at least) isn't particularly affected by ads or tracking sites. Well not that I know of anyway 🙂
