I checked this problem once again. It looks like that trafficlight extension has problem with - websearches. For example it works with Bing and Facebook, but doesn't work with Google, Yahoo etc. So I excluded of course any conflict with eset products.
Yes, I know that Eset also block phishing sites but after entering on them. That's why I need also something more preventing that I can double-check information about website before I come into.
I have uBlock origin extension too, but uBlock block only adverts as far as I remember.
I know about WOT extension but I have mixed feelings about that. But thanks for suggestion :).
