Just looking at some Safari extensions and I noticed one called 'DoNotTrackMe'. Installed it after doing a little research to see it has many positive reviews etc. Very surprised to see how many trackers are being blocked - this page alone has blocked 6 trackers! Anyway, are there any negatives to using this extension?? I havent noticed it, but does it slow the browser at all?? Anything to be aware of?? Just after some feedback from others who use the extension - seems very handy but Im always wary of using new extensions like this just in case. Should I have any concerns? Thanks.
