By default, when you download and install a new Mozilla Firefox browser on your computer, you can only use it with one profile. The Firefox browser stores user data – including bookmarks, settings, saved passwords, history, cookies, and everything else – in one location, a specific folder named “Default”. That’s the reason why you need to sign out your Facebook or email account before logging into another account.
Now, you don’t need to do that anymore, because you can create as many Firefox profile as you want. And run multiple Firefox profiles at once. Each profile has a separate profile folder, and won’t conflict with the others.
It’s a good idea to set up different browser profiles for personal use, work, private browsing or testing purposes. With multiple profiles, you can easy to log into one website with different accounts. For example, open two Gmail accounts at the same time never been easier, and you don’t need to sign out any account.
Google Chrome also has this feature, and it appears to use to choose. But in the Firefox browser, it’s hidden. To use multiple profiles in Firefox, you need to enable it with a simple trick. This method also works with other Mozilla products, such as Thunderbird email client.
