Submission + - Mozilla is working on a big Firefox redesign, here is what it looks like (neowin.net)
From the mockups, it appears Mozilla took some inspiration from Googles Material You (or at least, the dynamic color extraction part of it) because the browser color accent appears influenced by the wallpaper setting. Choosing a mint-green desktop background automatically shifts the top navigation bars to match that exact shade.
Mozilla has a habit of redesigning Firefox every few years. Before "Nova," there was the "Proton" redesign in 2021, the "Photon" redesign in 2017, and the "Australis" redesign in 2014. Nova is still in early development, so it might take a year or two before it appears in an official stable Firefox release.
Neowin adds:
Not every redesign project ends well for Mozilla, though. You might remember 2012sFirefox Metro, an ambitious attempt to build a custom browser for Windows 8s touch-first interface. The team built it to operate both as a traditional desktop application and as a touch-optimized Metro app.
The whole thing was scrapped in 2014 after two years in development due to a dismally low user adoption rate (a preview version of the software had been released a year earlier on the Aurora channel).
