Little Snitch 4 for Mac can control your private outbound data and remind you about the outbound network connection in real time. It is very easy to use and very important app for your MAC, especially if you want to install many cracked mac apps. The program is very light but you need to check your mac os.

Little Snitch Mac

Little Snitch 10.14
The title says it all. I upgraded to MacOS Mojave and now neither Firefox nor Google Chrome can reach any Web site. Firefox says 'Unable to Connect' and Chrome says 'This site can't be reached'. Safari and Opera don't have this problem.
I have two user accounts on this iMac, one Standard for normal use and one Administrative because you have to have one. Only the Standard account has this problem. Firefox and Chrome behave normally in the Admin account. Ditto for my wife's Macbook pro: it was upgraded to Mojave and has no browser problems.
The problem is limited to two browsers on one account on one installation. What could Firefox and Chrome have in common that would be on only one account? (Surely it's not one problem on Firefox and a different problem on Chrome both triggered by the OS upgrade.)
Note: I have Adblock Plus and Ghostery on Firefox (so does my wife's computer) but no extensions or add-ons on Chrome. I uninstalled Chrome and reinstalled; no help.
