Works with the latest nightlies Rated 5 out of 5 stars
This add-on works for me (with a compatibility override) even in SeaMonkey 2.6a1 without Mnenhy or Enigmail, even though it only advertises support for the long-gone SeaMonkey 1.0 and only with either of these other extensions enabled.

The last update is from 3 years ago, it's total crap, doesn't apply to RFC2369 at all!
The header 'List-Unsubscribe' is still completely ignored...
Update for Thunderbird 3? Rated 5 out of 5 stars
This is one of those simple but very useful extensions, and I hope it doesn't get abandoned...
I'd really like to see an update for this for Thunderbird 3, since I've just made the move permanently...

It's not useful to display these links in the expanded headers, when the urls are already viewable in the expanded headers, and in most cases, in the message footer. Why can't they be in the condensed header view?

I have Enigmail installed and I select a message with the headers List-Help, List-Unsubscribe, and List-Post. Nothing is different from before. What should I see? Seems to not work right.
So how do I know setup is correct after the install? Rated 3 out of 5 stars
I have to read RFC 2369 to see which header should be enabled in Mnenhy to make sure it is displayed (when present) in the header pane of a message? Couldn't you just tell us? Okay, so I went and read RFC 2369 and the headers used are "List-*", like List-Help and List-Unsubscribe. After installing this add-on and performing the obligatory restart of Tbird, I made sure the Extended Normal View for Mnenhy was selected and then went to customize that view to ensure the List-* header were selected. They were not. So does this add-on go searching through the headers despite that Mnenhy has this disabled for that view? After the install of this add-on, Mnenhy's Extended Normal View does *not* have any of the List-* headers enabled. I won't know if this add-on works until someday in the future when someone happens to send me a newsletter that complies with RFC 2369 (ratified 1998). It'd be nice to know this was setup correctly before that long wait. The author's web site provides no additional info beyond what is presented here.
