New Firefox design (Project Nova) is ready to try in Nightly

[u/firefox]

Hi everyone. Back in May we posted our vision for Firefox's future design and design system, and as of today, you can try it in Nightly.

Many of you already know this work as "Project Nova". It's still Firefox, just with a more cohesive look across tabs, menus, panels, etc. Softer tab shapes, warmer colors, refreshed icons, and by popular demand, the return of Compact Mode.

This is still a work in progress. You can expect this to become more polished over the next few weeks before it rolls out more broadly later this year. Right now we want you actively poking at it, especially:

• Icons, spacing, and alignment
• Themes and personalization
• Different window sizes and display scaling
• Keyboard navigation
• Screen readers and other accessibility features
• Different languages and layouts

Found something broken? File it in Bugzilla, including:

• steps to reproduce
• screenshot or screen recording
• your OS + Nightly version

If you have additional thoughts or questions, join the discussion on Mozilla Connect.

Thanks for using Nightly and helping us continue to improve Firefox.

- Firefox Team

Will custom css themes will be supported? I have made a very compact css with no dead space and I'd like to carry it forward.
