I’m not getting any functionality. I’ve been using “Extended Copy Menu (fix version)” for years for this but finally started looking for a WedEx alternative.
I added Copy PlainText then disabled Extended Copy Menu (fix version) and restarted the browser. I see Copy PlainText in my context menu but clicking it does nothing. The context menu disappears but nothing is actually copied to my clipboard.
I’m not sure where to look in the console for more info. I installed v1.5 on Firefox 56.0.2 (64-bit) on Windows 7 Enterprise.
