Can't paste text into Google Docs in Firefox

I use Firefox 57.0.4 (64-bit) on Ubuntu 16.04 LTS

I am unable to paste in Google Docs. CTRL-V doesn't work. I can paste in a comment on google doc, but not in the main document.

I am not sure if it related, but when I paste in facebook, the comment boxes just disappear. I have to refresh the page for them to return. If I type one character before I paste, it works.

I have a second laptop that runs Ubuntu. Firefox is synced with that one. I can paste on that laptop.

That laptop runs firefox 57.03 and Ubuntu 16.04 LTS.


Solution 1:

Just to note, for me such a problem was caused/solved by the privacy setting dom.event.clipboardevents.enabled.

When I opened Firefox about:config and set dom.event.clipboardevents.enabled to true, the Google Docs clipboard functionality started working.
