Running multiple instances of Thunderbird

You can run multiple instances of Thunderbird with different user profiles for each instance, by launching it from command line as:

[[email protected] ~]$ thunderbird -no-remote -P work &
[[email protected] ~]$ thunderbird -no-remote -P personal &

The -P option defines the profile name. If you want to create a new profile, use -P without a name.
