What’s in the latest Firefox update? 90 unblocks Facebook sign-ins, updates in background
Mozilla on Tuesday bumped Firefox to version 90, launching an enhanced version of its anti-tracking technology that allows exceptions for logging in to sites with the user’s Facebook credentials.
The outfit’s engineers also patched nine vulnerabilities, five tagged as “High,” Firefox’s second-most-serious label. Two of the nine were found only in the Android edition of the browser, but none were marked “Critical,” the most dire flaw category.
Firefox 90 can be downloaded for Windows, macOS, and Linux from Mozilla’s site. Because Firefox updates in the background, most users can relaunch the browser to install the latest version. To manually update on Windows, pull up the menu under the three horizontal bars at the upper right, then click the help icon (the question mark within a circle). Choose “About Firefox.” (On macOS, “About Firefox” can be found under the “Firefox” menu.) The resulting page or pop-up shows that the browser is already up to date or displays the upgrade process.
