Furthermore don't touch my ability to paste into web forms. Some banks do this, and I have no idea why (some incredibly misguided idea of security?). I disabled the ability for websites to disable pasting using Firefox's about:config, but 99.9% of users won't know they can do this.

Have you encountered any unintended consequences from disabling this?

None whatsoever. I've had it disabled for about two years.

The consequences of dom.event.clipboardevents.enabled;false mostly results in errors of functionality with WordPress, Google Docs, and Facebook (but I suspect FB has other motivations/reasons for this). You might encounter errors with other WYSIWYG editors, but for the most part, it's a nice optional feature to have control over.

Do you know the key for this? Can't find it with a quick search.

You want dom.event.clipboardevents.enabled set to false

Does this also work the other way? Prevent copyjacking?

Yes, at least for the specific code discussed in this example.

Excellent, many thanks.
