How To Use Firefox Profiles & Run Multiple Firefox Profiles At Once

Chris Hoffman 18-04-2012

multiple firefox profilesFirefox stores your browser data – bookmarks, history, preferences, extensions, and everything else – in a directory known as a profile. Each user account has a single profile by default, but you don’t have to restrict yourself to just one — you can create multiple profiles and even run multiple Firefox instances with different profiles as the same time.


Set up separate profiles for work use, personal use, extension testing, secure browsing – anything you like. With separate profiles, you can also log into a website with different user accounts at the same time – say, to have two Gmail inboxes open at the same time 4 Ways to Simultaneously Manage Multiple Gmail Accounts Many of us have multiple Gmail accounts to separate private email from work and projects.

Launching The Profile Manager

Firefox’s Profile Manager can’t be accessed from within Firefox’s interface. To launch it, you’ll need to start Firefox with the -p option (make sure you use a short dash instead of a long one). If you’re already running Firefox, shut it down by clicking the Firefox menu and selecting the Exit option.

Once you have, click the Start button and copy and paste one of the following lines into the search box in the Start menu.

Using Multiple Firefox Profiles At Once

If you try to launch the Profile Manager while Firefox is already running, Firefox will just open a new browser window using the current profile. You’ll need to use the -no-remote option to launch multiple instances of Firefox with different profiles at the same time. To do so, use the same commands as above, but add the -no-remote option.

Select another profile to launch it – don’t worry, Firefox won’t let you use a profile that’s already in use.

Creating Shortcuts

You can also launch a specific profile with the -p option – just add the profile’s name. For example, use the following line to launch the default profile on a 64-bit version of Windows:

“C:\Program Files (x86)\Mozilla Firefox\firefox.exe” -p default

If the profile’s name has a space in it, enclose the name of the profile in quotes.


Once you know this, it’s easy to create special shortcuts that launch the Profile Manager or a specific profile – with or without the -no-remote switch to let you run multiple profiles. Just create a copy of an existing Mozilla Firefox shortcut, right-click it, and select Properties. In the Properties dialog, rename the shortcut and add the options to the Target field.


Create as many shortcuts as you want and use them to easily launch Firefox with your desired options.


ProfileSwitcher Extension [No Longer Available]

To easily switch between Firefox profiles from Firefox’s menu, install the ProfileSwitcher extension. Remember, you’ll have to install the extension separately in each profile you want to use it from.

    I have a specific website which will only run correctly on an older version of Firefox. I use two profiles to "launch" the appropriate version.

    Honestly , I tend to ignore your site from the search engine results I don't know the specific reason maybe due to unpopularity (not exactly I mean , I hope you woudn't be offended) or I haven't read your sites articles yet , or I tend to usually visit sites with a domain name of howto , maketo , how2 , etc.. that lacks on information and too confusing.

    But after reading your article I see that not all domain namestarting with howto or makeuse are usually useless post or article. Your site is well detailed , noob friendly tuts and updated. Thanks for the Firefox Profile Articles ( I badly need this one) I really appreciate it. :)

      Try launching the Run program (click Start, type Run and press Enter -- you'll also find it in the Accessories folder under All Programs), and typing the path into there.

    I would definitely recommend for users to install Mozilla's Profile Manager, a portable application: It adds even more control over firefox profiles. You can create temporary profiles, copy, delete and run profiles in new instances. This application will eventually replace firefox's built-in manager.

      Neat, thanks Ben -- I had no idea there was a new Profile Manager in development.

      Firefox really should expose this better -- Chrome has a very slick interface.

      Yup, you should be able to do that if you open multiple Firefox sessions with different profiles at the same time!
