Google this week introduced multiple security fixes for the desktop edition of its Chrome browser and Mozilla has also done the same for Firefox and Firefox Extended Support Release.

Google's stable channel update to version 83.0.4103.97 for Windows, Mac, and Linux has patched six bugs, four of which were rated high in severity.
