Quote:With a Firefox effort called Project Fission, Mozilla is moving ahead this month with a plan to keep a major class of computer attacks at bay.

The Spectre and Meltdown attacks, more broadly called side-channel attacks, have been a major issue for the computing industry since they emerged a year ago. Mozilla fixed the immediate security vulnerabilities in Firefox last year, but now with an overhaul called Project Fission, the company hopes to protect the browser from any future Spectre-class variations.

Fission has been underway for months. But Mozilla plans to take its first concrete step later this month with a release called Milestone 1, said Nika Layzell, a Firefox platform engineer, in a blog post Monday.
