Zen Browser 1.21.8b Released as a Maintenance Patch for Spaces, Split View, and UI Glitches
Zen Browser 1.21.8b drops today as a straightforward maintenance patch built on the Firefox 152.0.6 engine. The update quietly resolves four specific usability bugs, including permanently stuck Spaces, rogue windows spawning during split-view drag-and-drop, and a lingering UI gap when dismissing promos. You won't find any new features, security advisories, or base engine jumps in this release, which keeps the browser strictly on polish rather than innovation.
