Make Firefox the default browser
Right now it's set to Falkon, one of our own (several) web browsers. It's understandable for us to want to encourage the use of our own software, but in this case it's problematic:
- Almost no distros actually ship with Falkon as the default or only web browser. All other distros need to manually patch this file to reflect reality.
- Falkon is frankly not competitive with the major players of Firefox and Chrome. It periodically uses an old version of QtWebEngine which prevents some of our own websites from loading in it. I wish this wasn't true, but it is.
In the absence of the hundreds of thousands of person-hours materializing that would be required to make Falkon competitive, I think it's time to defeat for now and make Firefox the default browser. This is a reasonable default since the majority of Linux distros ship with Firefox as their default or sole browser anyway, and https://pkgstats.archlinux.de/fun/Browsers/current says Firefox still has majority market share among that sample of our users.
