We've decided to update XKit. It's harder than it looks. We're not in contact with the original XKit Guy, nor do we have access to xkit.info. We currently operate at this blog and on GitHub.
I enabled the mass deleter for my likes but it's not showing up..
That’s quite strange. Could you please send an ask with an extension dump? To generate one, open the XKit control panel, click the Other tab, and go to Export Configuration > Extension Info Export.
