It’s been two weeks since the release of Firefox 57, the first version of a new generation for the browser dubbed Quantum, and it’s clearly faster, cleaner, and lighter than its predecessors.

Firefox 57.0.1, released on November 29, addresses a few minor problems in 57.0. The release notes mention security fixes, but the linked Security Advisories page shows fixes that were already in Firefox 57.0. So there’s no particular urgency about this update, unless you’re affected by one of the issues the new version fixes.
