Shortkeys for Firefox problem to load kantu bookmarklets

Hi

I read here UI Automation Open-Source Selenium IDE plus additional features, iMacros alternative a solution to automatize the run of Kantu macro via bookmarklets with the ShortKeys extensions.

I installed ShortKeys for firefox and do like this post Activating bookmarks - #2 by admin - UI.Vision RPA - UI.Vision RPA Software Forum | Discuss RPA Automation, Selenium IDE and OCR API Text Recognition without success.

This solution working with ShortKeys for firefox too ?

Someone can test it and help me to use bookmarklets with the ShortKeys extensions with firefox (not Chrome) ?

ShortKeys addons is for Chrome and Firefox but on firefox I can’t use it for run Kantu macros.

Thanks, have a nice day
