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 rare mozilla W, was hoping for a page detailing all the ways platform holders fuck people over

really hope this page gets to the people who need to know this (lawmakers mainly), especially with the iOS bullshit, cause sideloading wouldn't be enough for things like JIT and child processes

ik it's not mozilla's forte but something similar for gaming platforms would be fire
