The latest release, version 149, delivers new features for the browser, including a built-in VPN, Split View mode, and more.
Mozilla has started rolling out Firefox 149 to all users in the Stable Channel. The latest release delivers several notable feature updates (announced previously) that improve productivity and privacy, including a native Split View mode, a built-in VPN, and more.
With version 149, Firefox offers a built-in Split View mode that lets you browse two pages side-by-side. This feature is pretty common in modern browsers, and Firefox is finally catching up. You can launch this feature by right-clicking a tab and selecting “Add to Split View.”
Another big change in Firefox 149 is the built-in VPN. It is available in the US, UK, Germany, and France (gradual rollout), with a 50GB monthly cap. Note that, unlike traditional VPNs, Mozilla’s built-in solution does not allow you to select a routing country, so those who want a more advanced option should consider dedicated VPN providers.
Another interesting new feature comes from Firefox Labs. The Tab Notes feature lets you add additional information to your tabs.
Split View and built-in proxy are the main features in Firefox 149.0, but there are more improvements. The rest of the changelog includes better performance for PDF files, improvements to website notifications, and new languages for the built-in translator:
- Many PDF files will now load significantly faster thanks to hardware acceleration.
- Firefox now automatically blocks notifications and permanently revokes permissions for any website flagged as malicious by SafeBrowsing. This prevents unsafe sites from sending background notifications to users, commonly used for ads, spam or phishing.
- You can now add a Share button to your toolbar via Customize Toolbar, making it easy to share the current tab using your Windows or macOS system sharing options.
- Address Autofill is enabled for users in Australia, India, Italy, Poland and Austria.
- Firefox error pages have a fresh new look, with updated visuals that better match the overall feel of Firefox. The redesigned pages create a more cohesive experience while making it clearer what went wrong.
- Explore more of the web with new on-device translation support for Bosnian, Norwegian, Serbian and Thai, plus improved accuracy for Croatian.
As usual, the update contains security fixes and various changes for developers and enterprise users. You will be able to find full release notes on the official website.
Firefox 149 is now available for download from Mozilla’s FTP. Existing users will get the update in the coming hours.
