Rated 5 out of 5 stars

With about 4,500 folders the QuickFolder tools were essential and it still surprises me it's not a standard build in feature. I'm grateful for it and happily pay.

I tried to install the Prerelease version but Firefox would not download and install it: "Firefox has prevented this site from installing an unverified add-on. "

Update: I used Chrome to download the Pre-release and have installed it OK. All is well again! I have a current license - it's money well spent.

This review is for a previous version of the add-on (4.18.1). 

Thanks for the support - I am actually investing quite a bit of money to bring all my Add-ons up to speed for Tb78; this is only possible because I decided to monetize the Add-on a few years back. Great to know that I made the right choice.

The very latest prerelease can be found here:
