Geez....what a dope I was.....after installing the extension you simply goto the TOOLS in the menu (the one that is on the very top, to the left..... If yer a dope like me, just RIGHT-CLICK the mouse after the last visible tab & click on 'MENU BAR'......now don't ya feel like a schmuck---I know...I know....I know.......enough ta make ya spit.....I know......Now once you have the menu bar goto 'TOOLS', & scroll down to the 'Manually sort folders' item....click it......up pops the sorting box........now yer on yer own....have fun.....works a treat on Thunderbird Portable v68.12.0 (64-bit)

This review is for a previous version of the add-on (2.0.2).
