Nova Redesign Has Become The Default **[It's Foss](https://daily.dev/sources/itsfoss)** · 5 min read · 0 upvotes · 1 comments ## Summary Firefox 157 ships the Nova redesign as the default look, rounding out tabs, toolbars, the address bar, and settings menus with a pill-shaped, gradient-accented style. The final design toned down the leaked March mockups (no floating island toolbar or lifted web content container). Other additions include an improved Tab Groups experience, a returning Compact mode density option, new installable themes, and a Classic/Smart Window switcher for AI-powered browsing. Users who dislike Nova can revert it via about:config by setting browser.nova.enabled to False. Existing Linux users on Ubuntu/Fedora and similar distros should receive the update through routine system updates. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I disable the Nova redesign in Firefox 157 and go back to the old look? Type about:config in the address bar, accept the warning, search for browser.nova.enabled, and toggle it to False. This reverts Firefox 157 to the pre-Nova interface without needing to downgrade the browser version. _daily.dev keeps developers current on browser UI toggles and config flags like this one._ ### What changed in the Firefox Nova redesign compared to the original leaked mockups? The floating toolbar island and the lifted, rounded web content container from the March leak did not ship. Firefox 157 instead delivers a more refined look with rounder tabs, menus, and address bar, a subtle gradient on the active tab, and redesigned settings panels presented as rounded cards. _track how design leaks compare to shipped releases by following browser updates on daily.dev._ ### What happened to Firefox Tab Groups in the Nova redesign? Tab Groups, which first landed in Firefox 138 as simple colored strips with only naming and collapsing options, now sit more naturally in the tab bar with smoother switching and collapsing. The List all tabs button also got a new icon matching the pill-shaped Nova style. _developers tracking browser feature maturity can follow updates like this on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@ghost** · 0 upvotes > It looks absolutely terrible.
