Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

Mozilla Thunderbird v146.0 Full Packages

The email and productivity app that maximizes your freedoms.
These are the full setup files, not the downloader versions.




Freedom from Chaos
Waste less time finding browser tabs.
Access all your messages, calendars, and contacts in one fast app. Filter and organize the way you like. Manage all accounts separately or in a unified inbox. Thunderbird simply makes your life simpler.

Freedom from Manipulation
Mozilla's agenda isn’t hidden. It’s to make the world better.
Thunderbird doesn't collect personal data, sell ads in your inbox, or secretly train AI with your private conversations. Thunderbird is open source. As part of the Mozilla family you can be confident they always put your privacy and security first.

Freedom to Geek Out
Thunderbird is yours.
Thunderbird is clean and elegant by default, but easily customizable to match your workflow and visual preferences. It is loaded with unique and powerful features.

v14.0
New:
Drop-down drawer is now enabled

Fixed:

During account setup, 'Your Name' field was mislabeled as 'Display Name'

Ope! Hold on, Speedy.
You gotta read this before you download below:

There are no ads, no fake download buttons and no crapware here.
This website has lived for 18 years solely through donations.
You can download without donating but we use the "Honor System"
here in the Ozarks. If your momma raised you to be honorable,
make your donation to keep things running.
Your momma would be so proud!

Thank you! -Randy & Deanna (The Older Geeks)
