But I have noticed some strange things starting with version 93 to the current version 94.0.1. I’m a Firefox fan and have been using it for ever. Note that Firefox 94.0.1 will be released for all supported desktop operating systems, even though it fixes an issue that affects only Mac OS X 10.12. Most browser installations have likely been updated by now through the browser's built-in automatic updating system.

These paint the interface using specific color palettes. Firefox 94 fixed several security issues besides that. Most users may have noticed the new Colorways palettes that users can select during first start after the upgrade or installation, or in the themes manager.

The main culprit seems to be full screen video playback on Mac OS X.įirefox 94 Stable introduced several new features, at least for some users. The update will be released later today by Mozilla it will resolve the issue on Mac OS X 10.12 as well once installed. At least one other site, Twitch, was confirmed to cause the issue as well under certain circumstances.Ī quick workaround was to set the preference full-screen-api.macos-native-full-screen to TRUE on about:config.
