Everything New in Firefox 151: Home Page Revamp, PDF Tools, and More

Firefox 151 arrives on May 19, 2026, bringing a fresh take on the browser's new tab page, now officially called Firefox Home. Alongside a subtle visual update, Mozilla introduces practical PDF merging capabilities and other refinements. Whether you're a daily driver or a curious tester, this release polishes the browsing experience without overhauling it. Below, we break down the key changes in a Q&A format, with links to each topic.

1. What is Firefox Home and how is it different from the old new tab page?

Firefox Home is the rebranded new tab page in Firefox 151. While the core functionality remains the same—showing shortcuts, top sites, and recommended stories from Pocket—the interface receives a mild facelift. Mozilla describes it as “a new look and feel,” though the changes are evolutionary rather than revolutionary. The most noticeable difference is the redesigned search bar, which now features a rounded pill shape that previews the upcoming Nova design language. Additionally, the search bar is no longer sticky; it scrolls with the page, giving you more room for content. The name change from 'New Tab' to 'Firefox Home' signals a shift toward treating this page as a personal starting point rather than just an empty slate.

2. What specific design changes were made to the new tab page in Firefox 151?

Several tweaks refine the visual experience. The search bar adopts a soft, pill-shaped appearance and stops sticking to the top when you scroll. The Stories section remains in place, but the “follow” button for topics has been replaced by a simple plus-sign icon (+) located to the left of the section header. This icon is cleaner and less intrusive than the previous button. Overall, the spacing and alignment have been adjusted to create a more airy layout. The color palette and typography stay consistent with earlier versions, so returning users won't feel lost. These changes align Firefox with modern design trends while maintaining the familiarity that long-time users appreciate.

3. How has the search bar changed and why is it significant?

The search bar now appears as a rounded pill shape, a direct nod to the Nova redesign that Mozilla is gradually rolling out. This shape is more modern and visually softer than the previous rectangular bar. More importantly, the search bar no longer remains fixed at the top of the page when you scroll down. This change gives you more vertical space for exploring stories and shortcuts. While some users may miss the sticky convenience, the new behavior aligns with a cleaner, content-first approach. The search bar also includes a subtle animation on focus, and its placeholder text has been updated to encourage queries. This design shift is significant because it signals Mozilla's long-term direction toward a more unified, touch-friendly interface across all Firefox products.

4. What happened to the 'follow' topic button and where can users find it now?

The previous “follow” button for topics—which let you subscribe to interest categories like technology or sports—has been replaced by a concise plus-sign icon (+). You'll find this icon to the left of the section header in the Stories area. Clicking it opens the same topic selection menu as before, allowing you to follow or unfollow topics with a single click. The change reduces visual clutter while preserving full functionality. Mozilla likely made this switch to streamline the experience and align with the minimalist design language of Firefox Home. If you were used to a wordy button, the icon may take a moment to locate, but it behaves identically once you find it.

5. Can users still customize their new tab page with stories and shortcuts?

Absolutely—customization remains intact. You can still pin, remove, or reorder shortcuts (top sites) just by hovering over them. The Stories section continues to display personalized article recommendations from Pocket, which you can dismiss or save. The “gear” icon in the top-right corner opens a settings panel where you can toggle the visibility of shortcuts, stories, and sponsored content. There's also a new option to reset the page layout to default. In short, Firefox Home retains all the flexibility of the old new tab page while polishing its appearance. If you prefer a completely blank page, you can still disable these features entirely through the settings menu.

6. What new PDF features does Firefox 151 include?

Firefox 151 adds a long-awaited capability: PDF merging. You can now combine multiple PDF files directly within the browser's built-in PDF viewer. To merge, simply open one PDF, click the new “Merge” button in the toolbar, and select additional files. The merged document can be reordered by dragging pages and then saved as a single PDF. This feature works offline and respects your privacy—no data is sent to external servers. It's a handy tool for anyone who frequently works with PDFs, from students compiling notes to professionals consolidating reports. Mozilla also improved PDF rendering performance and added support for more complex form fields. No other major PDF changes were announced in this release.

7. Are there any other notable improvements or fixes in this update?

Yes, Firefox 151 includes several under-the-hood enhancements. Security fixes address vulnerabilities found in previous versions. Performance improvements make page loading faster for cached websites. The browser now better handles memory usage when multiple tabs are open. For developers, the WebExtensions API received updates that allow extensions to interact more seamlessly with the new tab page. Additionally, the macOS version benefits from improved trackpad gesture recognition, while Linux users get better font rendering on high-DPI displays. Mozilla has also updated the Firefox Screenshots tool to allow quick edits before saving. These smaller changes, combined with the headline features, make Firefox 151 a solid, incremental upgrade.

8. When will Firefox 151 be available and how can users get it?

Firefox 151 begins rolling out on May 19, 2026. It will be available for Windows, macOS, Linux, and Android (though the iOS version may lag due to App Store policies). Most users will receive the update automatically through Firefox's background updater. If you want to force the update, navigate to Menu > Help > About Firefox and click “Check for Updates.” The browser will download the latest version and prompt you to restart. For those on the Beta or Nightly channels, this version has already been tested. As always, you can also download the installer directly from the official Mozilla website. Make sure to back up your profile if you're manually installing on a different system.
