Mozilla released Firefox 53.0.2 on May 5. The new version includes three bug fixes, one of them for a security vulnerability.

As usual, Mozilla did a lousy job of announcing the new version: in fact, they didn’t bother at all, apparently preferring to leave that job to others like the far more dependable CERT.

If you use Firefox, and you’re not sure which version you’re running, open its menu (click the ‘three horizontal lines’ icon at the top right), then click the question mark icon, then About Firefox. If an update is available, this should trigger it.
