The reason why I support Gecko and Ladybird’s engine is because I am opposed to monoculture, however. Even if Gecko (Firefox) is less secure than Chromium (Chrome, Edge, etc.), by not having a monoculture, a Chrome exploit will only take down the subset of people using the Chromium ecosystem, and not affect Gecko users. Alas, most people are in the Chromium ecosystem right now so that means malicious hackers only need to target one codebase.
It’s the same reason I wrote MaraDNS back in 2001—back then, there was only one open source DNS server[1,2] so I wrote another one.[3]
[1] Djbdns was around back then but wasn’t open source, which limited its adoption.
[2] MaraDNS was and is optimized for running at most a few dozen domains on a system running a bunch of other services, where one does not want the DNS server causing security problems for the server, and where the DNS server needs to be lightweight as possible.
I know this is old: https://madaidans-insecurities.github.io/firefox-chromium.ht...
but has the situation changed substantially in favor of Firefox?
