Hi,
since a week ago, I was using ublock origin. (not a crap ! it's doing its job with low ressources, if you don't susbcribe too much lists).
Than, after reading MT, I've replaced it with adguard and Avira Browser Safety.
It was just to try AdGuard, but I kept it, don't know exactly why. It seems light, easy to configure... no big list of lists.
I was not a fan of something like Avira BS, but it's free, light, nice look, easy to use. Don't slow down browsing.
I did a few personnal tests with some malicious url. Some where blocked by BD Free (my current AV), others by AdGuard, and others by Avira BS, so it seems usefull.
