Firefox doesn't have support for AppleScript and this is crucial to my browser habits/workflow. Both Safari and Chrome/Chromium-based browsers have it. Once/if Firefox adopts it, which I doubt but hope so, I'll consider using it.
I don't know anybody who uses Signal and isn't a programmer (on the cryptography/security side) or journalist that needs it in order to work. Anybody else uses Telegram, WhatsApp, or both. SMS if you're in the USA.
As someone who's new to programming and doesn't know Ruby at all, can you (or someone) please explain how it works, what it does, and how would someone use it?
I would love to see this money ($30M) being given to Andreas Kling and others behind Ladybird (the browser from SerenityOS). I'm pretty sure in 1-2 years they would have a better browser than the current Firefox.
