Download Free Thunderbird Offline Latest Version – It’s easier to upgrade to Thunderbird 3.1 from older versions of Thunderbird and other free email clients like Outlook and Outlook Express.
Our new Migration Assistant will help you set up Thunderbird the way you want it. And our import tools help you bring your emails, address books, and settings from your older email program to Thunderbird 3.1.
Tabs and Search
If you like Firefox’s tabbed browsing, you’re going to love tabbed email. Thunderbird 3.1’s tabbed email lets you load emails in separate tabs so you can quickly jump between them.
Search results open in a new tab too. New tools like our timeline and filtering tools will help you pinpoint the email you’re looking for, whether it’s the one from yesterday, last month, or several years ago.
