I have been using this app since 4 years ago, it never let me down. If you have sometimes problems to see any special page, you might go and allow the page to open, just for one time. I find it a very neccesary tool for the usual internet use of today. It also takes care of many Facebook-google tracking you have whenever you open sthing. Just do a usual check up on the icon to see if you are blocking all that might hurt you or be intruding. Kepp the app, up to date!
