Good point, To get to correct place...if you then select the 'Thunderbird ' link at top of page you will then find the 'Beta' link. https://www.thunderbird.net/en-US/channel/

Where can I download Thunderbird beta and choose the 64 bit and choose my language? Thank You

David Use the link previously provided

• https://www.thunderbird.net/en-US/channel/
• Then click on 'Systems & Languages' link which is just below the 'Thunderbird Beta' download button.

Or go directly to that page via this link:

• https://www.thunderbird.net/en-US/thunderbird/beta/all/

Just had a thought, you mention 64 bit. This link will get you to verion 60.0b10

• http://ftp.mozilla.org/pub/thunderbird/releases/60.0b10/win64/

Or so you are not on Beta channel see http://ftp.mozilla.org/pub/thunderbird/releases/60.0/win64/

The Win64 Tb 60.0 is not considered an officially supported Release yet though.
