This is a good read on why monthly donations are more helpful for the GNOME Foundation than yearly or lump-sum donations. I've used GNOME for many years, and contributed to it for about half those years, and I'd love it if you'd like to join me there on the "Friends of GNOME" page

It has indeed been a difficult year for GNOME, financially. If you benefit from GNOME as a user, we really need your donation:

So grateful to see this work hit the world!

Standards is an interesting process - I was the initial champion of this proposal, along with @b.trl.sn and @mattjohnsonpint.bsky.social.

Since then @pipobscure.com , @jason-williams.co.uk, @ptomato.name and so many others have done more than we did.

I have to admit I do not know β€” I work on WebKit separately from Safari, and don't have a macOS that can run the current Tech Preview builds. But I'd assume it's in Develop β†’ Feature Flags

Are you a developer who has a browser use-case for ShadowRealms?

Does it solve a specific need for you that current technology (iframes) can't?

If you answered yes and can share these with me, let's chat. (DMs are open). Please repost for visibility/reach.
