Well, one of the very best browsers you can get for the Classic Amigas is NetSurf.
The good developer(s) over at AmiSoft have been slowly updating this great browser and have gotten us to version 3.4. The AGA-only version was released back in March of 2015, and there is a new version that does not require the cumbersome ixemul library file that was released near the end of June 2015.
I decided to test these and see how they compared to the ixemul-dependent 3.2 I’d been using. This is a quick glance test, not comprehensive.
