If you dont want to wait for developer changes, try this!

It's work in TB5 with few small changes:
1. download extension, rename to [extension_name].zip, extract
2. Open install.rdf find:
<em:maxVersion>3.2a1pre</em:maxVersion>
and edit:
<em:maxVersion>5.0</em:maxVersion>
Save file and close.
3. Go to chrome->content and open file markAllReadSubfolders.js
4. Find line:
var appVer3Orlater = version.substring(0,2) == "3.";
now replace 3 with 5 (TB5)
var appVer3Orlater = version.substring(0,2) == "5.";
Save and close
5. Zip all contents, rename to [extension_name].xpi and install.

Tested on TB5 (Fedora 15, x64, KDE)

Good luck!
