Scratchpad uses CodeMirror 5, Copyright © Marijn Haverbeke and others. CodeMirror is released under the MIT License.

User reviews
Thank you so much for that extension! Scratchpad was one of those features which made Firefox special and I seriously missed it once it was gone. I hope one day mozilla will stop trying to imitate chrome and gets back to what really matters: security, user convenience and outstanding features!
