Rated 5 out of 5 stars

As Olav Seyfarth noted in his review of March 1, 2011, the rdf file can be edited to change em:maxVersion from 3.1.* to a later version of TB, in this case 5.0.* (or 5.1.*, etc.)

Instructions:

Download the add-on to your PC and unzip the xpi file. The unzip will create the folder "folder_account-3.1-tb".

In this folder, edit install.rdf using Wordpad or a similar plain text editor, and change em:maxVersion to 5.0.*

Save the changes, then create a new zip file from the contents of the folder.

Rename the zip file to: folder_account-3.1-tb.xpi

Open TB5 and in the Add-ons Manager click the icon to the left of the Search all add-ons box, and choose option Install Add-on from file.

Select the xpi file above, and run the install.

Folder Account will then work with TB5, and your previous settings will be retained.

This review is for a previous version of the add-on (3.1).
