"Preview in Thunderbird" is the new default yes. As a workaround for this bug, you could change that to another default action. (In reply to clochrua from comment #5) Thanks clochrua. You are mostly right. Try to use some markdown formatting and blank lines in your comments to make them more readable. > If I "Open" a pdf attachment in a message displayed in a new window, nothing happens. I presume in this situation "pdf.js" does not have the correct environment required to run. Correct.

Nah, 2 prefs is too much, but we can try a separate intelligent default. I'll ask Alex ARNAUD in a separate comment what is best from his POV. > But from what I can see currently, it is not possible to set "preferences" to "Preview in Thunderbird" and display pdf attachments in either tabbed or windowed messages. That looks like a bug as it means you have to switch windows (back to the preview tab) in order to display a pdf. It's a bug for users of that preference, now confirmed :-)
