Currently I am developing an extension for Magento 2.1 and have incorporated a wysiwyg editor for some fields in that extension. Testing it in Chromium ( or Chrome ) works like a charm.
However when I tried it in Firefox, or Edge, there was no wysiwyg modus, though I didn't change settings in configuration.
Next I tried the already present wysiwyg fields in core extensions -like the field Description, area Content, in Categories- and found the same problem. No wysiwyg mode for any field in Magento 2.1 in Firefox nor Edge, though in Chromium there was no problem.
What I'd like to know is this a known issue, have anyone other the same problem? Or am I missing some sort of setting?
Forcing my customers to use only Chromium ( Chrome ) is not the answer imho.
