Why can’t I paste into youtube comments on firefox?
go to your address bar and type “about:config” (or copy and paste the text without the quotes)
then press the “I’ll be careful, I promise” button
next type “dom.event.clipboardevents.enabled” (or copy and paste the text without the quotes)
then double click it so the value is false.
Now try to paste in Youtube, you don’t need to close the page or reload/restart Firefox, it should be instant.
Please let me know below if it worked for you 🙂
