Hi Cathy,
Geesh! LOL It took me over 30 minutes to figure out where the "Unknown Sources were in the settings! I was trying to find it on my phone on the Google webpage where you install Adblockplus and it wasn't there. So I finally read what it said on that page and went my phone settings and found it under Security. I did everything it said then tapped download but it doesn't seem to be doing anything? Did I miss a step? Maybe I am just impatient. I'm used to everything downloading and installing in just a few seconds on this phone and it's not happening on this site. I'll keep you posted. ♥‿♥
