Issues with certain Firefox versions 

If you ever used Firefox to access ScaleFlyt you may have noticed some strange and irritating behaviour inside text fields. 

On certain versions of Firefox it is not possible to navigate inside multi-line text entries and select words or groups of words to copy, replace or delete them. 

This problem may be fixed by updating your version of Firefox or using a Chromium-based web browser, such as Google Chrome or Microsoft Edge, Opera, Vivaldi, etc
