Addon not working on Waterfox browser

[Itz_Dr_Li]

like title said, i just moved from firefox to waterfox, so the kis addon, but after i check, the addon can't connect to my kis even after i reboot my pc.

and as i know, some kis users are using waterfox too and their addon is working well, does any reason can cause my addon not working?
