Rated 5 out of 5 stars

Update: In Version 1.2 the problem still occurs, but it occurs a bit later comparing to v1.1. Initially it is working (even after closing/restarting Thunderbird), but at some point the option "Message Body as --> All Body Parts" vanishes from the menu and just won't come back. Please correct!

When downloading/installing this addon directly (through the addons tab) initially it works: I can see the option Message Body as All Body Parts.

However, when I close and restart Thunderbird, although the addon is enabled, the above option in the menu is no more there. You have to remove (disable/enable does not work) the addon and re-install to have the option again.

I have tried in three different computers with the same results.

Note: If I try to install from file (downloaded xpi) and not directly (through the Addons Thunderbird page), then the addon does not work: the option is not added to the menu at all.

Very useful addon, but please make it work!

This review is for a previous version of the add-on (1.1).

There is no "Show" menu option in Thunderbird 8.
Instead the instructions should read "View | Message Body As | All Body Parts".

I.e. just like the screen dump says.

This review is for a previous version of the add-on (1.1). 

You're right, of course. I've fixed it.
