Messes up buttons when editing Toolbars in FF 3.6 Rated 4 out of 5 stars

I love this extension, but there's a problem in Firefox 3.6.

Trackpackage 2.5 - and problem still exists in 2.6 - adds a huge mess of buttons in the toolbar config editor in Firefox 3.6.

Seems to be ok in Thunderbird, where I use it the most.

I've emailed the dev twice about it now, but still no resolution.

Will change to 5 stars once this is resolved.

This review is for a previous version of the add-on (2.6).
