Slight issue with compact headers addon - will not automatically expand the headers if they are compacted. However, toggling compact headers will still show the full headers, so it's still straightforward.

This review is for a previous version of the add-on (0.2). 

With both add-ons installed each shortcut works for me. I tested it with Thunderbird 9.0.1 and 10.0.2. Which version are you using?

The only thing that doesn't work is when the compact headers view is enabled pressing H has no visual effect (it still toggles which you will see when you disable the compact headers view). Is that what you meant?

Update: This is fixed in version 0.3
