What are profiles in Firefox. How to transfer your profile to Firefox. How to create and upload a new Firefox profile
Firefox saves your personal information such as bookmarks, passwords, and user preferences in a set of files called yours, which is stored in a separate location from the Firefox program files. You can have multiple Firefox profiles, each containing a separate set of user information. The Profile Manager allows you to create, remove, rename, and switch profiles.
- If you have (or plan to have) multiple installations of Firefox on one computer, see Dedicated profiles per Firefox installation .
- If you are troubleshooting a problem with Firefox: The Refresh Firefox feature can fix many issues by restoring Firefox to its default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process.

Use the selected profile without asking at startup
When you have multiple profiles, this option tells Firefox what to do at startup:
- If you check this option, Firefox will automatically load the selected profile at startup. To access other profiles, you must start the Profile Manager first.
- If you uncheck this option, Firefox will show you the Profile Manager each time you start Firefox, so that you can select a profile to use.
Use Sync with a new profile
When you first open Firefox in a new profile, a Welcome to Firefox page will open, with a space to enter your email address.
What is a profile?
Firefox stores all the information that the user generates while using the browser in a special folder called a profile. Data such as bookmarks, cookies, browsing history, browser settings and installed add-ons, and remembered passwords are saved. At the first launching Firefox the profile is created with default settings.
Profile folder location
Depending on the operating system The default profile folder is located in the following paths.
If you created this folder yourself through the profile manager and specified a path different from the one suggested, the profile folder may be located in a different location.
Windows 95, 98 and ME
C:\Windows\Application Data\Mozilla\Firefox\Profiles\ Select “Start → Run”; Enter %APPDATA%; Click OK. A window will appear Windows Explorer; IN Windows window Explorer, select “Mozilla → Firefox → Profiles.” Each subfolder in this folder is a profile on your computer. C:\Documents and Settings\ The Application Data folder is a hidden folder. To display hidden folders open Windows Explorer and select: Tools → Folder Options → View tab → Show hidden files and folders." Click the Start button to open the menu; Enter %APPDATA% in the Start Search field; Click on the “Roaming” item that appears in the menu; In the Windows Explorer window that opens, select “Mozilla → Firefox → Profiles.” Each subfolder in this folder is a profile on your computer. You can also directly navigate to this folder using the following path: C:\Users\ The "AppData" folder is a hidden folder. To show hidden folders, open Windows Explorer and select: Organize → Folder and Search Options → Folder Options → View tab → Show hidden files and folders. Profile folders are located in: ~/.mozilla/firefox/ The ".mozilla" folder is hidden by default. Profile folders are located in one of the following folders: ~/Library/Mozilla/Firefox/Profiles/ The tilde character (~) refers to the current user's home directory. So ~/Library is the /Macintosh HD/Users/ folder You can use the Open Profile Folder extension, which will open your profile folder if you use the corresponding menu item in the “Tools” section. It is not recommended to edit these files directly. Instead use user interface. The exceptions are three files whose name begins with "user". They are intended to be edited by the user directly. To get more detailed information about files, please refer to the table below. Let's imagine the situation. To work in the browser, you have configured panels and bookmarks for quick access to the required sites. For personal needs, this information is different. Is it possible to separate individual browser instances to separate personal from work activities? It turns out there is a way out. Let's look at how to create multiple Firefox profiles. Profile is a collection of settings and personal information. These are logins, passwords from social networks, design themes, start page. They are recorded in files and stored in a special folder. Several profiles are needed for the following reasons: Let's edit the browser shortcut. Click on it right click mouse, then “Properties”. Switch the keyboard layout to English. By default, the suggested name is "Default User". I recommend changing it for convenience and increased security. You can write the name in Russian, but it is better to write it in Latin, so that there are no malfunctions in the future. Specify the storage folder yourself, but this is not necessary, you can leave it as default. If you leave everything else unchanged, when you start the browser, a manager will open in which you will have to select a profile and click on the “Launch” button. To prevent it from opening every time you start it, uncheck the box next to “Without prompting.” Perform the following sequence of actions: As a result, icons will be created for each profile, with saved bookmarks, passwords, and history of visited sites. The described method increases the security of storing personal information. Disable the browser, right-click on the icon, then in the “Properties” window in the “Object” tab, enter the parameter as in the screenshot: Place a space after the "p". Instead of Firefox saves your personal information such as bookmarks, passwords, and user preferences in a set of files called yours, which is stored in a separate location from the Firefox program files. You can have multiple Firefox profiles, each containing a separate set of user information. The Profile Manager allows you to create, remove, rename, and switch profiles. Type about:profiles into the address bar and press the EnterReturn key. This will open the About Profiles page. The following options are available: To manage profiles, find the profile you want to change and choose from these buttons underneath that profile: Note: Another way to start the Profile Manager is from the Search box in the Windows Start menu. Close Firefox (if open), press , type firefox.exe -P and press enter. If the above instructions do not work or if you have multiple installations of Firefox, use the following instructions instead.

To start the Profile Manager for a specific Firefox installation, replace firefox.exe in the above instructions with the full path to the Firefox program, enclose that line in quotes, then add a space followed by -P. Examples: After starting the Profile Manager as explained above, you can remove an existing profile as follows: After starting the Profile Manager as explained above, you can rename a profile as follows: Choosing this option loads the selected profile and starts Firefox without connecting to the Internet.

Hello everyone who has visited our website. In one of the previous articles, we examined in detail what the Mozilla Firefox browser is. This is the folder where all our Firefox settings are stored. It is created by default when you first install the browser. But sometimes a situation arises when several profiles are needed for this browser (for example, for other family members or just a separate one for work). How to do it? The Profile Manager will help us with this. With it, you can add, rename, delete a profile, and also set some settings. Before starting the manager, check whether it is closed Mozilla browser Firefox. If you have it open, then you need to close it. Then we will use . Press it and, without releasing it, press R (Win + R). A “window” will open in front of us, enter in the field firefox.exe -P And click " OK» You will see the profile manager in front of you. Here you will see your default profile, which stores all your data. To fulfill all further actions, which we will describe below, return to this screenshot. Let's say we want to create new profile, which would store bookmarks, history for work or another family member. To do this, we just need to click on the button “ Create…"(number 1). The Create Profile Wizard will open. Now we need to come up with a name for our new profile. Since we are planning to use it for production purposes, let's give it a suitable name, for example - For work. Or something else, at your discretion. Next, you need to specify the folder where the created profile will be stored. By default, a folder with the profile name is created. You can use this option. If you want to set your own, then click " Select folder..." And in the explorer indicate the desired folder. We recommend creating a clean, empty folder for the profile; if you install it in a directory that contains some files, you risk losing them when you delete the profile. Now that we have set a name and indicated a location, click “ Ready" A new profile will be created and will appear in the profile manager. Select the created profile and launch the browser. It will open in the same form as it was after the first installation: there will be no bookmarks, the history will be empty, and you will not find any extensions or applications. If, when creating a new profile, you made a mistake in its name or simply decided to change it, then this can be easily corrected. To do this, select the desired profile and select the button under number 2 - “ Rename». Then we give a new name or correct the error and click “ OK" The profile will be renamed. If you stop using a profile, you can safely delete it. To do this, select the appropriate button in the manager - under the number 3. We will be offered 2 removal options. Don't delete files. Selecting this option will remove the profile from the manager, but all your data files will be saved on your hard drive, which can be used for a new profile in the future. Delete files. In this case, deletion occurs not only from the manager, but also all files with your data and settings. The profile folder is completely removed from the computer. You will not be able to restore anything after this. Therefore, take this fact into account when choosing this option. Work autonomously. If you set this parameter for a specific profile, Firefox will start in offline mode, without an Internet connection. In this case, you can view sites that you have visited previously and conduct experiments with your profile. Launch the selected profile without prompting. If this checkbox is checked for a specific profile, then this profile will be loaded automatically when Firefox starts. If you need to switch between profiles, then uncheck this option. Now, every time you start the browser, you will choose the profile you need. Let me finish here, perhaps. Today we looked at how to create, rename, delete a Firefox profile. Share in the comments if you use your profiles in this browser. Until we meet again and good mood to everyone!!!
