All of the changes you make in Firefox, like your home page, what toolbars you use, extensions you have installed, saved passwords and your bookmarks, are all stored in a special folder, called a profile. Your profile folder is stored in a separate place from the Firefox program so that, if something ever goes wrong with Firefox, your information will still be there. It also means you can uninstall Firefox without losing your settings and you don"t have to reinstall Firefox to clear your information or troubleshoot a problem.

By launching an Internet browser, you can instantly get to the required page, provided that it has already been previously added to the useful notes section.

Where are bookmarks stored in Mozilla Firefox?

All actions regarding changes to the Firefox web browser, such as installing plugins, saving user personal data and adding bookmarks, are saved in a service folder called “Profile”. This folder is saved separately from the main search engine documents; this is done for reliability so that the user does not lose their data when deleting or reinstalling the browser.

To find your profile you need the following:

• Launch the Internet browser Mozilla Firefox;
• Open the browser engineering menu;
• Click on the icon located at the very bottom of the menu window with the image of a question mark.

You will see the same folder that you opened through the browser.

Be extremely careful when manipulating information in this folder. Since, by carelessly deleting some objects, you can ruin the performance of the Firefox search engine and permanently lose some important data.

All changes made in Firefox such as home page, the panels you use, the extensions you have installed, your bookmarks and saved passwords are stored in a special folder called a “profile”.
