Idk, on one hand I get what you mean. On the other hand, Firefox going away or being monetized in more aggressive ways will not be a good thing.
Honestly, I think I would prefer the lawsuit never happened and Google kept paying Firefox. Now, if Google loses, Firefox will likely head for enshitification. And if google wins, it sets terrible precedent :(
No, keeping up with new web standards, security, etc. is a full time job. It’s not something volunteers can keep up with. At that point, it may be better to just give up and build on top of Chromium.
In addition, without enough market share, websites will not test, let alone optimize for your browser. This is already causing issues for Firefox. Smaller browser engines stand no chance.
