Firefox 149 Now Available for Download, Brings Split View

A month after releasing version 148, Mozilla has launched Firefox 149, the latest update to its popular open-source web browser, now available for download, introducing performance improvements, new features, and security changes across desktop platforms, including Linux.
PDF handling is one of the key areas updated in this release. Many PDF files now load faster due to hardware acceleration. The built-in viewer also gains the ability to download images directly from PDFs via the context menu.
Another highlight is the new Split View feature, which lets you display two pages side by side in a single window. Tabs can be added to Split View via the context menu, enabling parallel browsing within a single workspace.

Security changes include automatic blocking of notification permissions for websites flagged as malicious by SafeBrowsing. These permissions are also permanently revoked, preventing the use of abusive background notifications commonly used for ads or phishing.
The address bar interface has been updated with a new TrustPanel. It combines privacy and security information into a single panel, replacing the previously separate views.
On Linux systems, Firefox now defaults to the XDG portal file picker when available, replacing the GTK3 dialog.
On Windows, the WebRender layer compositor is now enabled, reducing power usage during full-screen video playback and improving WebGL and WebGPU performance. The browser also switches to the modern Windows geolocation API.
Other user-facing changes include a new Share button that can be added to the toolbar and expanded Address Autofill support for users in Australia, India, Italy, Poland, and Austria. Error pages have also been redesigned with updated visuals.
Networking improvements include increased robustness for HTTP/3 uploads under unstable conditions.
For developers, the Storage Inspector now includes an option to delete all entries for the selected storage, and the Computed view allows jumping directly to CSS rules.
Those eager to download this update immediately can do so directly from Mozilla’s servers.
Windows and macOS users will get an over-the-air update in the next few days. Linux users should see Firefox 149 in their distro repositories soon, too.
