Firefox 149 Arrives with Built-In VPN, Split View, and Smarter Browsing Tools

by George Whittaker Mozilla has officially released Firefox 149.0, bringing a mix of new productivity features, privacy enhancements, and interface improvements. Released on March 24, 2026, this update continues Firefox’s steady push toward a more modern and user-focused browsing experience. Rather than focusing on a single headline feature, Firefox 149 introduces several practical tools designed to improve how users multitask, stay secure, and interact with the web. Built-In VPN Comes to Firefox One of the most notable additions in Firefox 149 is the introduction of a built-in VPN feature. This optional tool provides users with an added layer of privacy while browsing, helping mask IP addresses and secure connections on public networks.

Down: Debunking zswap and zram myths

Chris Down has posted a detailed look at how the kernel's zswap and zram subsystems work β€” and how they differ. Most people think of zswap and zram simply as two different flavours of the same thing: compressed swap. At a surface level, that's correct – both compress pages that would otherwise end up on disk – but they make fundamentally different bets about how the kernel should handle memory pressure, and picking the wrong one for your situation can actively make things worse than having no swap at all

Krita 5.3.0 and 6.0.0 released

The Krita project has announced the release of Krita 5.3.0 and 6.0.0: Krita 5.3/6.0 is the result of many years of work by the Krita developers. Some features have been rewritten from the ground up, others make their first appearance. Enjoy the completely new text feature: on canvas editing, full opentype support, text flowing into shapes. It is now easier than ever to create vector-based panels for comic pages. Tools got extended: for instance, the fill tool now can close gaps. The liquify mode of the transform tool is much faster. There are new filters: a propagate colors filter and a reset transparent filter. Support for HDR painting has been improved. The recorder docker can now work in real time.

However, the 6.0.0 release is the first based on Qt 6; it has more Wayland functionality but is
