Nel caso dovessi creare un nuovo profilo questi sn i file piu importanti da salvare:
Bookmarks and browsing history:
bookmarks.html (Firefox 2) - Bookmarks
history.dat (Firefox 2) - Browsing history of previously visited websites
places.sqlite (Firefox 3) - Bookmarks and browsing history. Note that Firefox 3 stores both bookmarks and browsing history in the places.sqlite file.
You can alternately import a bookmarks HTML file if you wish to add those bookmarks to your current Firefox bookmarks. In Firefox 3, you can also use the Firefox Library "Restore" feature to replace your current bookmarks with a bookmark backup file (such as a dated JSON backup from the bookmarkbackups folder of another Firefox 3 profile) but this will not transfer your browsing history.
Cookies:
cookies.txt (Firefox 2) or cookies.sqlite (Firefox 3) - Cookies
Download actions for file types:
mimeTypes.rdf - What action to perform when downloading certain types of files (save or open with a specified application).
Form history:
formhistory.dat (Firefox 2) or formhistory.sqlite (Firefox 3) - Saved entries for web forms and the Search Bar.
Passwords: (Both of these files must be copied)
key3.db - Key database for passwords.
signons2.txt (Firefox 2) or signons3.txt (Firefox 3) or signons.sqlite (Firefox 3.5) - Saved passwords. Note: signons.txt was used prior to version 2.0.0.2.
Permissions:
hostperm.1 (Firefox 2) or permissions.sqlite (Firefox 3) - Per-site preferences for allowing cookies, images, popups, and extension install permissions.
Preferences:
user.js (an optional file) and prefs.js - User preference settings. Not recommended to transfer if you had problems in your old profile. You may need to manually edit the paths in prefs.js to reflect the new profile location. If the new profile doesn't have the same extensions, you may have some unused preferences set by those extensions, but that usually doesn't harm anything.
Security certificate settings:
cert8.db
Session storage:
webappsstore.sqlite - Only copy this if you deliberately keep and use many saved sessions.
Spelling corrections:
persdict.dat - Personal (custom) entries in the spell checker dictionary.
Site specific settings (e.g. Page Zoom):
content-prefs.sqlite (Firefox 3 only).
[edit]
Folders
bookmarkbackups - Contains dated bookmark backup files:
bookmarks-(date).html (Firefox 2) or bookmarks-(date).json (Firefox 3)
Note: You can import an HTML backup file into any Firefox version. You can restore a JSON backup in Firefox 3 by opening the Library window, selecting "Import and Backup - Restore -> Choose File", and choosing one of the bookmark backup files in this folder.
chrome - Contains "example" files and optional user customization files (if created) that change the way Firefox and web pages look. Note: The chrome folder is no longer created by default (as of Firefox 4?). [1] [2].
userChrome-example.css
userContent-example.css
userChrome.css
userContent.css
userChrome.js
extensions - Contains added themes and extensions. Not recommended to transfer if you had problems in your old profile. After copying this folder or its contents to the new profile, delete the "extensions.ini", "extensions.cache" and "extensions.rdf" files from the profile folder. These files will be regenerated when you start Firefox. Note that some extensions store data in additional files in the profile, usually at the top of the directory. You'll need to move them separately.
searchplugins - Contains additional search engines, if you've added any to Firefox.
