holy shit mozilla has a new issue tracker documenting all of the ways that apple, google, and microsoft purposefully put third party browsers at a disadvantage and is calling for action https://mozilla.github.io/platform-tilt/
Platform Tilt - Mozilla

Platform Tilt tracks technical issues in major software platforms which disadvantage Firefox relative to the first-party browser.

@nano This is 🔥 and is *exactly* what Mozilla needs to be doing to build credibility & backing. It's so refreshing to see.
@dalias yeah this feels like a really old-mozilla move
