Your search results are displayed in a tab so you can easily switch back and forth to your search results and other email. Thunderbird also indexes all of your emails and chat conversations to help you search even faster. The search interface in Thunderbird contains filtering and timeline tools to pinpoint the exact email you’re looking for. You can also 'Pin' or save a Filter and use it across multiple folders. Or you can filter your email by New Messages, Tags, and people in your Address Book. Start typing in words in the Quick Filter search box and the results are displayed instantly.

The Quick Filter Toolbar lets you filter your email faster. There is also a Tab menu on the Tab toolbar to help you switch between Tabs. When quitting Thunderbird, visible tabs will be saved and will be restored when you open Thunderbird the next time. Tabbed email lets you keep multiple emails open for easy reference. Perhaps you’re responding to an email and need to refer back to an earlier email. Tabbed email lets you load emails in separate tabs so you can quickly jump between them. If you like Firefox’s tabbed browsing, you’re going to love tabbed email. The attachment reminder looks for the word attachment (and other words like file types) in the body of your message and reminds you to add an attachment before hitting send.

Two clicks and you can add more details like a photo, birthday, and other contact information. Add people by simply clicking on the star icon in the message you receive.
