Great to know about this add-on to exclude facebook extensions from offices staff for misusing it. Like it..

good

This addon is certainly useful and a smart idea, but only for those people who don't use uBlock or AdBlock. Or if they do but don't know how to use them...
Indeed, these latter addons can do the same thing either by enabling a blocklist named Fanboy's Anti-Thirdparty Social or by adding custom rules for that (my case).

Required field ( ͡° ͜ʖ ͡°)

Thank you I think this is very useful
becaus My facebook account is often stolen
