RAD Editor seems to be incompatible with latest version of Firefox v63.0. None of the buttons clicks leads to any processing, when using Firefox ESR 60.3 things seem to start working again.

Hi Vishwesh,

The problem happen when the editor is initially hidden and displayed. It is discussed in the following bug report item The editor commands do not work when the editor is initially hidden in Firefox 62+ and the solution is to fire the $find("RadEditor1").onParentNodeChanged(); method when the editor becomes visible on the page.

The problem will be fixed in the upcoming in mid-January R1 2019 release.

Best regards,
Rumen
