Clipboard broken due to dom.event.clipboardevents.enabled being disabled

[DaRacci]

Already looked at the Wiki?

Yes

Describe the Issue

I recently updated my FF-Ultima and used the user.js due to the new updates needing it.
After this i was unable to use any copy, paste or cut actions on a number of websites but first to come to mind are Zendesk and GitHub.

Interestingly GitHub only had the issue on my Windows machine and under Linux it works fine.

Secondary to this I don't believe telemetry/privacy user preference changes belong in this Project, this should either be explicitly noted that there are also some small changes regarding this or leave it to the projects that are dedicated to this.

The commit that introduced this is ec4e1eb

It was disabled to prevent invasive websites from listening to clipboard data, java event listeners from disabling right-click copy in other sites, it makes sense that some heavy telemetry or editorial focused might break without the ability to do so.

But anyway.. breakage isn't good. I'll switch it to True for the next update in case any other user isn't aware of the theme previously disabling it. *Before deleting it of course.
