Do you waddle the waddle?
Continuing its fast, two-week release cycle, Mozilla Thunderbird 159 is here to update the tray icon support for Linux systems to indicate unread mail and show the message count in the tooltip, and to introduce automatic detection of graph calendars when creating a new account.
Coming a week after KDE Plasma 6.8.1, the KDE Plasma 6.8.2 release improves the Activity Switcher sidebar to no longer stretch wallpaper images on screens without a 16:9 aspect ratio, showing the wallpaper faithfully and cropping it if needed instead.
For Linux users, Mozilla Firefox 159 improves memory usage on AMD GPU systems when viewing map or place results, fixes that very annoying tab detaching into a new window issue on Wayland, and fixes an issue with menus and panels fading in when animation effects are turned off in the operating system.
Mozilla Firefox 160 promises a new playback speed setting to the Picture-in-Picture player with options ranging from 0.25x to 2.0x speed, support for playing Matroska (MKV) files with FLAC, MP3, or PCM audio, and the ability to drag history entries from the sidebar to the tab strip to open them in new tabs.
Coming four months after Kali Linux 2026.2, the Kali Linux 2026.3 release is powered by the Linux 7.1 kernel series and introduces support for the KDE Plasma 6.7 desktop environment. Of course, Xfce 4.20 remains Kali Linux’s default desktop environment.
Earlier this month in the sister site we had this series about "Secure Boot" going bad (or worse). Now even Microsoft admits there is a problem and many GNU/Linux users are reporting issues related to that.
"Secure Boot" is not about security. It's about securing Microsoft's monopoly. We were right about that. It's also about pushing people to throw away "old" PCs and buy "new" ones. █
