When pasting add plain text option.
Hi, unfortunately, for now, you need to use a keyboard shortcut:
Ctrl+Shift+V (on Mac, Command+Shift+V)
I believe you can do that by pressing Shift+Ctrl+V. But yeah, context menu can also show this option
I want to +1 this suggestion. I used this feature a ton in Chrome. The Ctrl-Shift-V does not strip all formatting to plain text in Firefox on my tries. It is sorely missed and I hope Mozilla can add this to the context menu.
