Mozilla has released Firefox 85.0.1 and includes a fix that prevents a Windows 10 NTFS corruption bug from being triggered from the browser.
Last month, BleepingComputer reported that a bug in Windows 10 and Windows XP allows non-privileged users to mark an NTFS volume as dirty.
In Firefox 85 and earlier, the NTFS corruption bug could be triggered simply by trying to access the path in the browser's address bar.
With the release of Firefox 85.0.1, instead of trying to access the path, Firefox will simply ignore the path and not attempt to access it.
Existing Firefox users can upgrade to version 85.0.1 by going into the Firefox Menu and selecting Help -> About Firefox.
Firefox will then check for a new update, install it, and then prompt you to relaunch Firefox to complete the installation.
