I just started trying out your browser. I gave it a try because of the built in adblocker and the prospect to maybe one day get paid content based on blockchain technology (which I am interested in)
It is convincing in the first try, and the handling is quite similar to chrome. I use macOS Mojave 10.4.1, and I did not yet find a way to activate synchronisation. (This is not a support request, just a hint that it might not be so obvious how to do it. But sync is a must!!!)
All in all it will take some days or weeks to find out if this is really an alternative that I can live with.
Concrats for your bravety! It will be hard to compete with Chrome and IE. Go for it!!!
