# Release notes for version 1.24b By Steven Van · 2026-10-20 Zen Browser 1.24b ships an updated OneCRL list for compromised eMudhra certificates, plus sidebar, window and Windows crash fixes. Zen Browser 1.24b is a fixes-only release that includes an updated certificate block list. Mozilla [blocked compromised eMudhra intermediate certificates]() via OneCRL on October 17th, and the blocks reached clients through Remote Settings the same day. This update bundles the updated OneCRL list in the browser itself. [Zen Browser]() will therefore block those certificates even if Remote Settings is disabled by policy or unreachable on the user's network. ## Interface and sidebar fixes - The sidebar no longer hides while the mouse is still over it (#15995). - Sidebar scroll position is no longer reset when entering fullscreen (#14389). - Devtools now appear on glance tabs (#15261). - The Boosts zap bar now pushes the web contents up when activated (#13972). - Multiple media bars no longer appear when two or more tabs are using WebRTC. ## Startup, windows and crashes - Multiple windows no longer launch on startup on Linux and Windows (#12140). - Windows no longer open on the wrong monitor in multi-monitor setups on Linux. - A Windows crash when printing or saving a page as PDF while a screen reader or other assistive technology was running is fixed. ![Zen Browser]() Zen Browser Privacy-focused, beautifully designed browser built on Firefox — split views, workspaces, and a minimal UI for focused browsing.
