Well, kiwibrowser/src isn't updated because kiwibrowser/src.next is the actual up-to-date Kiwi Browser. Kiwi Next is similar to a beta version, and releases for Kiwi Browser are based on Kiwi Next. You can just compile Kiwi Next if you are paranoid. It's the best Android Chromium browser.
The whole search engine debacle was unnecessary, and that basically killed Kiwi's reputation even though it really had zero impact on anyone or anything. I mean, if the default search engine is something you don't prefer, it's just a few goddamn presses to change it to whatever you want.
It wasn't at ALL clear to me that this entire process takes place in two DIFFERENT Firefoxes: one on a desktop or laptop install and THEN on your android device!! Maybe I read thru the instructions too fast (real men don't read instructions 😉 ) but they all seem to say "...open Firefox..." without being clear WHICH Firefox they're referring to.
I've now spent close to 3 hours trying to get 3 extensions to work/load properly into Fennec on the Android... Back to Kiwi! "It just works..." 😡
