I can't wait for these new CSS features to be cross browser supported. They solve so many silly problems it is unreal! Customise select lists for example... Center text vertically... And so much more!

Wowza..!! That new ‘corner-shape’ property is great, there’s a lot of nice enhancements there. Edge runs off a Chrome engine so all we have to wait on is for Safari and Firefox to catch up then we’ll have more or less full compatibility.
CoPilot says this:
Firefox (Gecko)
• Usually 3–12 months behind Chrome for major new CSS features.
• Firefox tends to implement features once they stabilise in standards discussions and after Chrome proves real‑world viability.
• Example: Firefox adopted some modern layout features (e.g., subgrid) before Chrome, but for bleeding‑edge features like CSS Nesting, it lagged behind Chrome’s early implementation.
Safari (WebKit)
• Historically 6–24 months behind Chrome, sometimes longer.
• Safari is the most conservative engine and prioritises stability and battery efficiency.
• Apple’s release cycle (tied to macOS/iOS updates) slows down shipping new CSS features.
• Safari often becomes the last major browser to support newer features like container queries, :has(), and advanced color functions.
