Mozilla Starts Testing Site Isolation to its Firefox Browser

Firefox is Experimenting with this Savvy Chrome Security Feature Google Added in 2018

Mozilla is now testing a new security feature for its Firefox browser known as site isolation, following Google’s Chrome adoption in 2018…

Known for its privacy prowess, Mozilla’s Firefox browser is a well-known name to consumers who want to keep their online activity records to a minimum. It’s also one of the most secure browsers available. But, Mozilla thinks it can offer even more protocols. The company is in the midst of testing a new security feature for Firefox that Google built into Chrome about two years ago.

Mozilla Starts Testing Site Isolation to its Firefox Browser

The technology is called “site isolation,” and does precisely what one would think. It isolates websites open in different tabs in a browser at the same time. Since people generally run a few to multiple tabs at once, with various sites open, those open web properties can (and try) to access and collect data from others. This allows them to compile useful tracking data on consumers and more.

Site isolation is a guard against compromised sites (or outright malicious web properties) stealing data from other sites during a simultaneous browsing session. Threat actors can exploit flaws to collect private information, such as usernames and passwords, as well as other things, like encryption keys. Right now, it’s running in Firefox Nightly, an unstable experimental build. But, should make its way out to stable release in the not-too-distant future.
