Mozilla on Tuesday shipped Firefox 74. Wait, didn’t we just get a new Firefox a minute or two ago?
It may feel that way. Firefox 74 arrived just four weeks after its predecessor, continuing the faster release cadence promised last year.
The refreshed browser dropped support for the now-obsolete TLS 1.0 and 1.1 cryptographic protocols, blocked all add-on “side-loading” except that allowed by enterprise-managed group policy, and enabled support for a header element designed to safeguard against attacks based on the Meltdown and Spectre hardware-based vulnerabilities first revealed two years ago.
Mozilla’s security engineers also patched a dozen vulnerabilities, half of them labeled “High,” Mozilla’s second-most-serious threat label. As usual, some of the flaws might be used by criminals.
