Hi, in the latest version of F2C it is still loading Mootools. I thought maybe it was something to do with my template, but having installed a fresh copy of the latest Joomla and F2C as the only extension, using the sample data, when editing the Demo all fields submission F2C article in the frontend it is still getting loaded. (only on F2C edit pages).
I did manage to remove Mootools by changing some JHtml::_('behavior... lines to the bootstrap equivalent but this required editing core F2C files, which is not something I want to do on my livesite.
