Active development of an Amiga browser would be a great thing! If I had had the programming know how to make it happen I would use kickstarter to fund it. Since I don't have the ability I wouldn't launch such a vaporware cause. I get that the market is too small to do active development on the hopes of selling enough copies after the fact, but if you knew you could pull a project like this off within say a year you could do a kick starter with milestones through the year and funding amounts that made the project worth the persons while.
just a thought...
As to the TOR part, I agree with that has been said. We need a decent functioning browser and then worry about the rest.
