Comments from those who selected Thunderbird as one of their Top 10 Tools in 2008
- “Mozilla free e-mail program – light and easy to use, manages all my email accounts” Debora Gallo
- “Mozilla’s open source email application helps me share ideas with friends and colleagues” Guy Boulet
- “Email may be dead, but my email client continues to be a place of constant activity. Most of our corporate communications come by email, as do the various mailings lists I subscribe to, comments and enquiries from people around the world, and more. Email remains my primary communications tool precisely because it is asynchronous – I prefer to send and receive messages on my own schedule.” Stephen Downes
- “A solid e-mail program that I’ve never had any problems with. Like Firefox, it has a ton of great add-ons.” Adam Kosh
