Google Chrome has the site isolation feature built-in that runs each website in a separate process, this improves security. Google has integrated this feature in Chrome to reduce Spectre attacks, Mozilla is also working to bring this security to Firefox in the name of Project Fission, it now can be enabled and tested in Firefox 69 Nightly.
Enable Fission or Site isolation in Firefox
1. Ensure you’re using Firefox Nightly
2. Visit about:config
3. Search for fission, change fission.autostart the value to true.
4. Restart Firefox browser.
Do note the feature is still in development, you may not see benefits of it straight away, and to add, enabling this feature may also improve memory consumption. You can report fission bugs here.
Recently, we’ve reported Google Earth beta available for Firefox and Chromium browsers, but the best Earth experience is possible in Chrome browser only because it supports multi-threading fo WebAssembly.
Whereas Mozilla supports single threading due to disabling of SharedArrayBuffer. The Organization has disabled SharedArrayBuffer to prevent spectre and meltdown attacks, Mozilla can re-enable the feature back in Firefox once fission is enabled, you’re seeing one benefit right away with Fission project.
