Exceptions do not work in Phi Browser #252

Me again, I love trying out new browsers. So there's another one I'd like to see supported in Mojito: Phi Browser.

There are plenty of Arc alternatives popping up, now that Arc will sunset soon: https://igorsyrbu.github.io/awesome-arc-alternatives/
I don't know how much effort it takes to build those exceptions, but maybe some of them (stars on GitHub, regularly updated, whatever criteria you see fit) could make their way in Mojito.

I know that this might add unneccessary complexity, so if you decide not to support every niche browser, I'll be completely fine. 😂
