Firefox 145: A Major Release with 32-Bit Linux Support Dropped

2 weeks 4 days ago
by George Whittaker Introduction

Mozilla has rolled out Firefox 145, a significant update that brings a range of usability, security and privacy enhancements, while marking a clear turning point by discontinuing official support for 32-bit Linux systems. For users on older hardware or legacy distros, this change means it’s time to consider moving to a 64-bit environment or opting for a supported version.

Here’s a detailed look at what’s new, what’s changed, and what you need to know.

Major Changes in Firefox 145 End of 32-Bit Linux Builds

One of the headline items in this release is Mozilla’s decision to stop building and distributing Firefox for 32-bit x86 Linux. As per their announcement:

“32-bit Linux (on x86) is no longer widely supported by the vast majority of Linux distributions, and maintaining Firefox on this platform has become increasingly difficult and unreliable.”

From Firefox 145 onward, only 64-bit (x86_64) and relevant 64-bit architectures (such as ARM64) will be officially supported. For those still running 32-bit Linux builds, Mozilla recommends migrating to 64-bit or switching to the Extended Support Release (ESR) branch (Firefox 140 ESR) which still supports 32-bit for a limited period.

Usability & Interface Enhancements

Firefox 145 brings several improvements designed to make everyday web browsing smoother and more flexible:

  • PDF viewer enhancements: You can now add, edit, and delete comments in PDFs, and a comments sidebar helps you easily navigate your annotations.

  • Tab-group preview: When you hover over the name of a collapsed tab group, a thumbnail preview of the tabs inside appears, helpful for reorganizing or returning to work.

  • Access saved passwords from the sidebar, without needing to open a new tab or window.

  • “Open links from apps next to your active tab” setting: When enabled, links opened from external applications insert next to your current tab instead of at the end of the tab bar.

  • Slight UI refinements: Buttons, input fields, tabs and other elements get more rounded edges, horizontal tabs are redesigned to align with vertical-tab aesthetics.

Privacy, Security & Under-the-Hood Upgrades

Mozilla has also doubled down on privacy and risk reduction:

  • Fingerprinting defenses: Firefox 145 introduces new anti-fingerprinting techniques that Mozilla estimates reduce the number of users identified as unique by nearly half when Private Browsing mode or Enhanced Tracking Protection (strict) is used.

Collective Wisdom: Why the Future of AI Must Be Built in the Open

3 weeks 1 day ago

The recent GOSIM AI Vision Forum in Hangzhou crystallized the central paradox of artificial intelligence: how to harness its immense potential while mitigating its considerable risks. AI is already augmenting our capacity for knowledge work by simplifying discovery, synthesis, and translation, as well as automating routine tasks. This automation frees individuals to engage in more meaningful and creative endeavors. Yet, these advancements are shadowed by urgent challenges, including equitable access, value-aligned governance, and protecting our social fabric from harm. As Dr. Michael Yuan highlights in the foreword of the recent Linux Foundation report Global Cooperation for Human-Centered AI, aligning AI with human values is crucial, but equally important is preparing humans to collaborate effectively with AI—a shift that requires us to evolve our fundamental understanding of work, education, and creativity.

MX Linux 25 ‘Infinity’ Arrives: Debian 13 ‘Trixie’ Base, Modern Tools & A Fresh Installer

3 weeks 2 days ago
by George Whittaker Introduction

The team behind MX Linux has just released version 25, carrying the codename “Infinity”, and it brings a significant upgrade by building upon the stable base of Debian 13 “Trixie”. Released on November 9, 2025, this edition doesn’t just refresh the desktop, it introduces modernized tooling, updated kernels, dual init-options, and installer enhancements aimed at both newcomers and long-time users.

In the sections that follow, we’ll walk through the key new features of MX Linux 25, what’s changed for each desktop edition, recommended upgrade or fresh-install paths, and why this release matters in the wider Linux-distribution ecosystem.

What’s New in MX Linux 25 “Infinity”

Here are the headline changes and improvements that define this release:

Debian 13 “Trixie” Base

By moving to Debian 13, Infinity inherits all the stability, security updates, and broader hardware support of the latest Debian stable release. The base system now aligns with Trixie’s libraries, kernels, and architecture support.

Kernel Choices & Hardware Support
  • The standard editions ship with the Linux 6.12 LTS kernel series, offering a solid baseline for most hardware.

  • For newer hardware or advanced users, the “AHS” (Advanced Hardware Support) variants and the KDE Plasma edition adopt a Liquorix-flavored Linux 6.16 (or 6.15 in some variants) kernel, maximizing performance and compatibility with cutting-edge setups.

Dual Init Option: systemd and SysVinit

Traditionally associated with lighter-weight init options, MX Linux now offers both systemd by default and SysVinit editions (particularly for Xfce and Fluxbox variants). This gives users the freedom to choose their init system preference without losing new features.

Updated Desktop Environments
  • Xfce edition: Ships with Xfce 4.20. Improvements include a revamped Whisker Menu, updated archive management tools (Engrampa replacing File Roller in some editions).

  • KDE Plasma edition: Uses KDE Plasma 6.3.6, defaults to Wayland for a modern session experience (with X11 still optionally available), adds root-actions and service menus to Dolphin, and switches TLP out for power-profiles-daemon to resolve power widget issues.

  • Fluxbox edition: Offers a more minimal, highly customizable environment: new panel layouts, updated “appfinder” configs for Rofi, toolbar changes and themes refined. Defaults the audio player to Audacious (instead of the older DeaDBeeF).
