Spectre and Meltdown were vulnerabilities found in several processors from Intel, ARM and AMD. Although it seems that they were never exploited, they could have allowed hackers to access private information including passwords and encryption keys (a risk known as a side-channel attack). Most alarmingly, these flaws had been present in chip designs for over 20 years.
Mozilla acted immediately, and released an update (opens in new tab) to prevent malicious web pages reading private data. Now, the company is working on a project called Fission that will strengthen the browser and protect users from any similar vulnerabilities found in future.
- Firefox is following Chrome and Edge's example by muting autoplaying videos
- You might soon see recommended extensions (opens in new tab) while browsing with Firefox
- Mozilla has closed its Firefox Test Pilot program (opens in new tab)
Project Fission has been in progress for several months, but developers have just announced (opens in new tab) that a release called Milestone 1 will appear later this month.
There's no word yet on when Firefox Fission will be finished, but elements will be released in Firefox Nightly (opens in new tab) builds when they're ready.
"We aim to build a browser which isn't just secure against known security vulnerabilities, but also has layers of built-in defense against potential future vulnerabilities," Mozilla said in a blog post (opens in new tab).
