First, as a precaution, open the Thunderbird
profile folder.... for example, on a WinXP system:
C:\Documents and Settings\Alice\Application Data\Thunderbird\Profiles\
default.abc\
and make a backup copy of the
prefs.js file located inside.
Next, open the original
prefs.js file inside the profile folder with Notepad, find the line
user_pref("signon.rememberSignons", false);
and place the cursor in front of the line.
Delete the entire line or, if you prefer, place two slashes in front of the line, like this:
// user_pref("signon.rememberSignons", false);
Close the Notepad window and say YES when asked if you want to save the change.
[NOTE: While you are in the profile folder, check to see if you have a
user.js file and open that in Notepad also. You MAY have an entry in the user.js that is adding back the
user_pref("signon.rememberSignons", false); line... if so, remove the line in the user.js file..... I'm trying to cover all bases.]
Does that work?
If you still aren't able to save passwords, you could check to see if you have a Master Password set up, in case that's part of the problem. (I don't use that option myself.)
Tools -> Options-> Advanced -> Under Saved Passwords:
Click the Master Password button.
Is the "Use a master password..." box checkmarked? If so, click the "Reset Password" button and then UNcheck the box.
