Hi! I love this, just one problem is that it isn't working well with Facebook comments. When I paste the clipping on Facebook comments the comment box just disappears as seen in this GIF http://www.giphy.com/gifs/3o752cTQIWIOTgmtQ4 It's very useful for social media managers like me so hoping for a solution for this issue! :)
Facebook is preventing pasting of clipping text, and mass text inserts in general, into comment boxes as well as in Messenger. This may be an actual feature on their end, and there are no plans for Clippings to defeat it.
The Mozilla team is rolling out a fix for Firefox which should resolve the certificate issue affecting all add-ons. See their Twitter feed for details: https://twitter.com/mozamo/status/1124627930301255680
