Mozilla released Firefox 139.0.1 as a hotfix to resolve flickering and visual artifacts affecting NVIDIA GPU systems with mixed refresh-rate multi-monitor setups after Firefox 139 re-enabled a DirectComposition behavior that exposed a Windows 10 driver bug. The update restores the prior blocklist to prevent the problematic path, with single-monitor and AMD/Intel setups unaffected, and a new compositor path slated for testing in Nightly; users can update via Settings.
