Dear Qubes Community,
Many of you are upgrading to Thunderbird 78. The Qubes Thunderbird
extension, which allows you to easily open attachments in DisposableVMs,
has not yet been updated to work with this new Thunderbird release. You
can find the details in this bug report:
https://github.com/QubesOS/qubes-issues/issues/5861
However, while you wait for the extension to be updated, it is important
to understand that this extension is purely for convenience. It is not
required to do anything. You can do everything that the extension does
manually. For example, to view an email attachment in a DisposableVM:
1. Save the attachment in your email VM.
2. Open the file manager in your email VM (e.g., nautilus).
3. Right-click on the attachment and select "View in DisposableVM."
The extension makes this more convenient by automating the process, but
it doesn't do anything that you can't do yourself. Nonetheless, we are
working on upgrading the extension as soon as reasonably possible.
