Hello :) I want to block a few urls for my own good, i spend too much time on these websites. I have installed the addon silentblock for firefox which seems to be the only working app out there to block sites without rooting my phone and changing the hosts file. Now I need to configure a file called contentblock-regex.txt, apparantly that uses "regular expressions". I have no clue about how to do that whatsoever, so I am asking here in anybody could help me or quickly write this file so I can block my few websites. The sites I am trying to block are the following: www.9gag.com (most important) www.sinn-frei.com www.smsvongesternnacht.de www.funlinx.to www.brainblog.to this is the addon i am talking about: https://addons.mozilla.org/de/firefox/addon/silentblock/ once i changed the contenblock-regex.txt file i also need to set up the path for it in firefox. hope that there is anybody out there that can help, please :) ive been searching the web for hours now... cheers
