New gecko based browsers are rare nowadays but this one is especially unique to me because it is more than just “firefox with tweaks” like a lot of the ones I’ve come across. The UI is different, it’s working on custom settings, a new more powerful sidebar, a new theming system, and potentially IPFS/Dat support further down the line. It’s very early in development but it’s still impressive as it is.
Blink isn’t a fork of WebKit, it’s a improvement of WebKit, like WebKit is a improvement of KHTML from KDE. Gecko was a trademark of Netscape, first called NGLayout and was adopted by Mozilla in 1998 until today.
