Great tool, perhaps to help others migrating a large mail account to Thunderbird I came across a hidden limit of 10000 mail items in the defaults/preferences/removedupes.js file, that seemed to be stopping the search process and isn't visible as an adjustable parameter in the settings available from the add ons section of the Thunderbird menu.
Method I used was to save the xpi file to a drive location, change the extention to .zip, open the removedupes.js with Notepad++ and change the default value of the line:
pref("extensions.removedupes.processed_messages_limit", 10000);.I also changed the line pref('extensions.removedupes.yield_quantum',20000); (from 2500 to 20000).
Simply save the file once edits have been made and then send all the files to a .zip and then rename the extension back to .xpi. Use the "install add on from file" in the Add ons Manager (settings icon near top centre - looks like a gear/cog) and job done.
