Doesn't work

Edit:
Sorry for late reply
I don't know
it doesn't work at all in any site
I tried to disable all addons and keep it alone but it doesn't work
nothing happens when I click copy
ur other addon "Copy Link Title" is working fine

Edit2:
I found the cause
This is disabled in my profile for privacy
dom.event.clipboardevents.enabled
ur other addon can still work while this is turned off so I hope u can fix it :)
