I don't want enter master password in Firefox/Thunderbird everytime. I've got an idea to place the password manager files (key3.db and signons.sqlite -- or just one of them) on the TrueCrypt volume. I don't want to encrypt whole Firefox/Thunderbird profile, because I will lost the ability of diff backups (e.g. Previous versions in Windows) of the profile.

I have tried to use symlinks for that however it did not work. (Firefox after moving key3.db to a TrueCrypt volume and replacing it with symlink did not show any password.)

Can I specify somewhere that key3.db or signons.sqlite are located elsewhere?

UPDATE: When I would encrypt whole drive, then I will have to encrypt whole backups -- that I do not want to -- if something wrong happens to me, nobody can access the backups; or I can just forgot master password to backups. Currently, I am backuping everything unencrypted and also the small TrueCrypt file with passwords, keys, etc. -- if I loose the password to this TrueCrypt file, just passwords will be lost, but not my data.

CLARIFICATION: I do not want to backup passwords unencrypted.

You could just use Truecrypt to encrypt your drive? –  Justin Pearce Dec 26 '11 at 21:39
    
An alternative would be to install Firefox Portable & Thunderbird Portable inside a TrueCrypt volume. It might be the easiest, so you can't forget to decrypt the databases. Performance may suffer, but I am not sure. –  iglvzx Dec 27 '11 at 19:41

Have you tried symbolic links? I believe they can work across separate drives/volumes. –  iglvzx Dec 28 '11 at 17:55
    
Yes, see the second paragraph. –  TN. Dec 28 '11 at 21:07

Why don't you encrypt the entire drive using TrueCrypt, then you can backup your data from the running OS (i.e. truecrypt image has been supplied with password and is open/accessible) on a separate disk/DVD etc=> result: unencrypted backups, safe Thunderbird. Of course, if you're using image-based backup (a la Norton Ghost) of an offline system, that wouldn't work...

Wondering why the symlinks didn't work - they should be transparant.

Because then the Thunderbird passwords will be unencrypted in the backups. –  TN. Jan 7 '12 at 17:07
    
I didn't get that part from your question. Might be a good idea to edit your question: you don't want your keys backed up unencrypted, but don't care (or do you?) that your keys won't get backed up... –  reiniero Jan 26 '12 at 9:52
    
Ok, the question is updated. –  TN. Jan 27 '12 at 13:53
