You may be one of those users. If you like Thunderbird and you usually use different computers, now you can use this portable version of the well-known mail client and enjoy it on any computer.
Enjoy your preferences anywhere. Read your e-mails and send them. Access your contact list and feel free to e-mail your friends using any computer.
You only have to have it stored in your USB removable drive and plug it in the computer you want to use, run Thunderbird Portable and use your favourite mail client.
We have to say that it is exactly the same program than the original one, so you will not miss any feature.
