Frankly, it's not my daily driver because I don't know who you are and don't trust you. Using a (no offense) no-name browser is somewhat of a risk as the developer could potentially be recording personal info. Of course, I have no guarantee that Mozilla isn't either. However, and yes I'm fully aware of how silly this sounds, I trust Mozilla despite never looking at their code or knowing any of the developers.
I'm guessing privacy is important to you (since you have the option of using a VPN service as IAP) so I'm curious how you would allay my fears of using a random browser from someone other than the big three.
Either way, I wish you luck.
