CloseReview for Manually sort folders by RobertJ
Rated 5 out of 5 stars
Works great but only works with TB60 if you disable extensions.strictCompatibility as noted in the release notes of TB60.
Not sure how long this will work.
After some hacking around I found that this will also work by editing the install.rdf file in the xpi to set
<em:maxVersion>60.*</em:maxVersion> for the target application.
