Firefox users bouncing between work and personal accounts on a daily basis are probably tired of logging in and out, or switching accounts. Thanks to the new (and overdue) Mozilla-made Multi-Account Container extension, you won’t have to worry about remembering which account you’re logged into. If you’re unconcerned about separating work and personal accounts, you can still take advantage of multi-account browsing to preserve your privacy or discourage bad habits.
Mozilla’s Multi-Account Container extension is an add-on for the Firefox web browser. It works by separating browsing sessions and browser cookies, putting them in their own “Container” tabs that act independently of one another, even though they’re in the same web browser window.
