What information is stored in my profile?
Note: Only important information useful for recovering is described.
- Bookmarks, Downloads and Browsing History: The places.sqlite file contains all your Firefox bookmarks and lists of all the files you've downloaded and websites you’ve visited. The bookmarkbackups folder stores bookmark backup files, which can be used to restore your bookmarks.
- Passwords: Your passwords are stored in the key3.db and signons.sqlite files.
- Site-specific preferences: The permissions.sqlite and content-prefs.sqlite files store many of your Firefox permissions (for instance, which sites are allowed to display popups) or zoom levels that are set on a site-by-site basis.
- Search engines: The search.sqlite file and searchplugins folder store the search engines that are available in the Firefox Search bar.
- Personal dictionary: The persdict.dat file stores any custom words you have added to Firefox's dictionary.
- Autocomplete history: The formhistory.sqlite file remembers what you have searched for in the Firefox search bar and what information you’ve entered into forms on websites.
- Cookies: A cookie is a bit of information stored on your computer by a website you’ve visited. Usually this is something like your site preferences or login status. Cookies are all stored in the cookies.sqlite file.
- DOM storage: DOM Storage is designed to provide a larger, more secure, and easier-to-use alternative to storing information in cookies. Information is stored in the webappsstore.sqlite file for websites and in the chromeappsstore.sqlite.
- Security certificate settings: The cert8.db file stores all your security certificate settings and any SSL certificates you have imported into Firefox.
- Security device settings: The secmod.db file is the security module database.
- Download actions: The mimeTypes.rdf file stores your preferences that tell Firefox what to do when it comes across a particular type of file. For example, these are the settings that tell Firefox to open a PDF file with Acrobat Reader when you click on it.
- Plugin MIME type: The pluginreg.dat file stores Internet media type related to your installed plugins.
- Stored session: The sessionstore.js file stores the currently open tabs and windows.
- Toolbar customization: The localstore.rdf file stores toolbar and window size/position settings.
- User preferences: The prefs.js file stores customized user preference settings, such as changes you make in Firefox Preferences dialogs. The optional user.js file, if one exists, will override any modified preferences.
- User styles: If they exist, the \chrome\userChrome.css and \chrome\userContent.css files store user-defined changes to either how Firefox looks, or how certain websites or HTML elements look or act.
