Rated 5 out of 5 stars

As good as this extension is, it is rarely updated when new Thunderbird versions are released. Now that Thunderbird 5 is out we can start using Thunderbird Conversations (adds Gmail-like threading) which actually incorporates a Slideshow-like feature. So for those sick of waiting for Slideshow to be updated, go check out Conversations:

This is a terrific addon, it certainly makes sharing photos in email more useful. This is the addon that is preventing me from upgrading to Thunderbird 5, it would be nice if the "Website" link were updated to the new maintainers' website with a link to the "Tbird-5 compatible version" mentioned in another review reply.

Thanks!

Great addon, abandoned Rated 5 out of 5 stars

To those asking about an update to Tb 3.1, I have contacted the developer and he has no intentions of updating the extension as he himself no longer uses Thunderbird. Too bad, this was a great addon and should probbly be part of Tb itself.

This review is for a previous version of the add-on (1.3).
