Profile backup

Find your profile folder. To completely back up your profile folder, copy your profile folder to another location.

For a more limited backup (not adequate for the Mozilla Suite or Thunderbird if you are using either for email), copy the following files and place them in a safe location. Some of these files may not exist (that is OK).

• bookmarks.html -- Bookmarks.
• user.js -- User preferences.
• prefs.js -- User preferences and default preferences.
• cookies.txt -- Cookies.
• hostperm.1 -- Cookies' allow/deny list.
• signons.txt -- Password file.
• key3.db -- Supplements password file. Needs to be copied along with signons.txt.
