As expected from a Google sponsored framework, https://angular.dev/ only works on Chrome, what a surprise.

Seems to work fine in Edge, Firefox, Opera, and Safari for me. What's broken for you?

"We're currently working on supporting Firefox with our development server. Meanwhile, try running the page using a different browser. " The playground says.

Have you tried using the playground?

Chrome, Edge, Opera, and Safari seem to work fine with the playground. Firefox doesn't like it, though. It's the 5th most popular browser (it seems), so I'm not super surprised at that. It works on 92% of the browsers out there (possibly more, I only checked these five), which is GREAT for a beta website. And the message that appears in Firefox does state that support is on its way.

Edge and Opera are basically Chrome skins for all pratical purposes rendering ChromeOS APIs.

Safari, well I am not on a Mac, nor do I own an iDevice, so whatever.

Well, I'm just letting you know that Angular works on all the major browsers, not just Chrome. And the new Angular website also works on all the major browsers, though the Playground is still under development and doesn't support Firefox yet.

Really liked the changes.

Uses idiotic classes and "decorators"...pass

Why are classes and decorators idiotic? That seems pretty strong.
