I’ve been using Firefox on desktop and mobile exclusively for a number of years now. I will say the experience isn’t perfect but it’s better than using a browser made by a company that is actively hostile to its users.
It is important to take note that you will experience issues with some websites. For example, https://astro.build/ Try scrolling quickly up and down on this page on Firefox vs Chrome (on mobile).
This is not an answer to your question but it’s tangentially related.
Someone I greatly respected ran an open-source project with the policy of merge everything. Completely flip this idea of carefully review, debate and revise every PR. His theory was that it helps to build an open community, and if something breaks someone else will revert that commit. He says that the main branch was almost always stable, a massive improvement to how it was run previously. He passed several years ago and for some reason this reminded me of him.
I guess what I’m trying to say is if you get something out there that people find useful, the code will be looked at. It doesn’t help you if you’re looking for someone to collaborate sorry.
