[Trisquel-users] Re : Transfer Thunderbird Mail History from Mint Backup to Trisquel?

[lcerf]

Move to anywhere so that the application does not find the it (it is like  
removed except that it is just elsewhere and you can move it back if you  
need/want).

I believe you only need to copy the profile (the folder that ends with  
".default") from the original to ~/.mozilla/abrowser and overwrite the file  
profiles.ini with that of the original system.
