Is this the first time you’ve heard about multiple Firefox profiles? In that case, you should know that profiles are separate browsing profiles that run independently of each other. Each profile has its own folder that stores bookmarks, browser settings, add-ons, browsing history, cookies, cached files, and other data.
This is a very handy feature that helps you clone your Firefox browser into different versions. For example, you can create a new Firefox profile just for reading newspapers or watching videos, and another profile for doing more important things like checking your emails or using for online payments. Mozilla Firefox stores the browsing data of each profile in different places, and you can clear the browsing data of one profile without affecting other profiles.
Previously, you could only create and run multiple Firefox profiles with Profile Manager, but now it's more straightforward because you can do the same things within the browser. Mozilla Firefox allows you to manage profiles while it's running. You can quickly create a new browser profile, launch it, rename or remove it, as well as set it as a default profile within the browser.
To access this feature, you need to type about:profiles into Firefox's address bar, and then press Enter. The next step is to bookmark this page for quick access in the future.
How To Create Multiple Firefox Profiles On Your Computer
If this is the first time you're using multiple profiles, you will see a profile named Default in the About Profiles page. This is the profile you are still using every day.
To create a new Firefox profile, click on thebutton.
In the Introduction window, click on thebutton (or if you use Windows) to move to the next step.
Next, you need to choose a name for this new profile and set a new folder to store the browsing data if you want. After that, click on thebutton (or , in Windows), and your Firefox profile will be created.
Go back to the About Profiles page; it has five function buttons that you can use, which are:
Open Folder (or Show in Finder, on macOS)
Use to open the data folder that contains the browsing history, cookies, cached files, settings, and much more. You can use this button to quickly locate where the data folder of a specific profile is, as well as easily transfer a Firefox profile from Windows to macOS and vice versa.
You can use it to rename a profile to identify it from others. Give it a unique and memorable name in case you use multiple profiles.
Use this option to delete a specific Firefox profile in case you don't want to use it anymore. Mozilla Firefox gives you two options: delete profile data files or don't. If you select to remove your profile and delete profile data files, then all the data related to that profile will be erased and can't be restored. However, if you choose the "don't delete files" option, those files will be there. You can quickly restore your Firefox profile by creating a new profile in the same folder. One thing you should know is that you can't delete the default profile. If you want to delete a profile that is currently the default profile, then set another profile to the default, and then you can delete the previous profile.
Set as default profile
Use this option to set a specific profile to be the default profile. It's the profile that will run first when you click on the Firefox icon.
Launch profile in new browser
Use to open the selected Firefox profile and run independently. If the selected profile doesn't have this button, it means it's running.
The good news is that Mozilla Firefox has allowed us to run multiple profiles at once. You no longer need to add an extra element into system settings and its shortcut anymore.
However, selecting and opening a Firefox profile is not as convenient as Google Chrome. In the Chrome browser, you just need to click on the icon in the upper right corner, then select the profile you want to open. I hope Mozilla will bring this tiny handy option into Firefox soon enough.
