Use sane about:config value: dom.event.clipboardevents.enabled = false
While reading through various about:config security hardening guides, I found several bad default values for the Tor Browser:
- dom.event.clipboardevents.enabled = false
- Disable that websites can get notifications if you copy, paste, or cut something from a web page, and it lets them know which part of the page had been selected.
