Firefox developers understand web browser security is at a premium, so they've started rolling out a new site isolation feature. That's a good thing because Firefox is an important browser that has brought about game-changing features over the years.
Mozilla has begun rolling out a new security feature for its Firefox browser in nightly and beta channels that aims to protect users against a new class of side-channel attacks from malicious sites. "This fundamental redesign of Firefox's Security architecture extends current security mechanisms by creating operating system process-level boundaries for all sites loaded in Firefox for Desktop," Mozilla said in a statement.
Mozilla has started rolling out the Site Isolation security feature to all Firefox channels, protecting users from attacks launched via malicious websites. Until today, Site Isolation could only be enabled by users of Firefox Nightly, the release channel used by Mozilla to test new features not yet ready for a wider rollout.
The bug listed here is what's known as a Universal Cross-site Scripting vulnerability, which means it's a way for attackers to access private browser data from website X while you are browsing on booby-trapped website Y. That's definitely not supposed to happen. Your browser is supposed to stop data such as cookies "Leaking" between websites, or else site Y could peek at data such as your login details for site X, and abuse that site-specific data to masquerade as you on site X and hijack your account.
The Mozilla Foundation fixed a flaw in its Firefox browser that allowed spoofing of the HTTPS secure communications icon, displayed as a padlock in the browser address window. Successful exploitation of the flaw could have allowed a rogue website to intercept browser communications.
The "Problem child" that Firefox just addressed is a lesser-known JavaScript variable called window. Specifying an existing tab name in the target of the link means that we can re-use the second tab for our new content, so that the example.com page opens up in the same NEWTAB tab, replacing the Naked Security content and avoiding the creation of a third tab.
Mozilla this week released Firefox 88 in the stable channel with patches for a dozen vulnerabilities and with improved user privacy, obtained through isolating the window. Name property has been available for websites to store whatever data they choose to, but such data has often been allowed to leak between sites, essentially allowing for the tracking of users across the pages they visit.
This month, Mozilla has announced plans to phase out support for the Firefox web browser app on the Amazon Fire TV product line. Although Firefox will be no longer supported on Fire TV effective at the end of this month, Amazon Silk web browser app remains available to Fire TV users.

The new Chromium-based Microsoft Edge browser has grown by over 1,300% in the past 12 months, while the Firefox browser is slowly losing its market share. In January 2020, Microsoft released the first stable version of the new Chromium-based Microsoft Edge browser and announced that they would slowly release it to Windows 10 users.
