What is Thunderbird?
Thunderbird brings email, calendars and contacts into one desktop application. It suits people who want to handle several mail accounts without switching between webmail tabs. Keep accounts separate or combine incoming mail in a unified inbox, then use filters and tags to organize messages. The interface can be customized to fit your workflow.
This download is the English (US) Windows x64 EXE for Thunderbird 159.0 on the Release channel, not ESR or Beta. It requires Windows 10 or later. Add-on compatibility is not universal: the publisher warns that the Release channel may not work with every add-on.
What it offers
- Manage multiple email accounts separately or through a unified inbox.
- Keep calendars and contacts alongside email in one desktop application.
- Organize messages with filters and tags.
- Customize the interface to suit your workflow.
Good to know
- The Release channel may not work with every add-on; check the extensions you depend on.
- This 159.0 package requires Windows 10 or later; it is not the publisher's separate Windows 7/8.1 download.
