Firefox previews site-isolation tech in move to catch up to Chrome Project Fission is part of a long-term effort by Mozilla to harden Firefox s defenses by isolating malicious sites and components.
Mozilla has announced that a years-long effort to harden Firefox s defences can now be previewed in the browser s Nightly and Beta builds.
Debuting as Project Fission in February 2019, the project was also linked to the more descriptive site isolation, a defensive technology in which a browser devotes separate processes to each domain or even each website, and in some cases, assigns different processes to site components, such as iframes, so they are rendered separately from the process handling the overall site.

Google has released a proof of concept (PoC) code to demonstrate the practicality of Spectre side-channel attacks against a browser s JavaScript engine to leak information from its memory.
Google in 2018 detailed two variants of Spectre, one of which – dubbed variant 1 (CVE-2017-5753) – concerned Javascript exploitation against browsers. Spectre targeted the process in modern CPUs called speculative execution to leak secrets such as passwords from one site to another malicious site.
