about:config
browser.nova.enabled
change true to false
this should be the standard

Don't forget "pdfjs.enableNova" to "false" too, if you don't like Nova when viewing PDFs in Firefox
I think a restart may be required for that one to take effect 🤔

Cosmetic changes should always be optional during an upgrade or installation. The Nova code should be an optional component because otherwise it unnecessarily consumes memory. It is strange that the trend of forcing such changes on users has reached Firefox as well. Many of us still use older machines whose performance is made artificially "insufficient" precisely by this kind of "improvement".

If the new Nova design is bothering you, there's a simple fix. Just go to about:config in your Firefox address bar, search for browser.nova.enabled, and change the value from true to false. This should revert the interface back to the standard look. Hopefully Mozilla makes this the default option for users who prefer the classic layout. While browsing for fixes and tutorials, this platform can help you save useful guide videos for later reference.
