Mozilla has released Firefox 76.0.1 to resolve bugs that caused the Amazon Assistant browser extension to no longer function properly and to fix a browser crashes on Windows 7 32-bit systems with Nvidia graphics cards. The issue was 100% reproducible on a variety of machines, Mozilla says. Mozilla decided to pause the rollout of Firefox 76 while the bug was investigated. The fix would be rolled out in Firefox 76 0.1, which was released this morning, and fixed the issue with Nvidia drivers.
