Hello! Please, I am having problems to enjoy this extension, already installed, in my Firefox, from a few days to here. I'm with Mozilla Firefox, in this version: (57-0-1-64-bit).
In the upper corner of my browser, the Stylish icon, the following message appears: "An error has occurred using the Stylish database. Would you like to visit a web page with possible solutions?"
Please, to the engineers and technicians of "Stylish", I love this extension, but I'm sad that it stopped working. Can you instruct me so that I can solve this mistake?
Right now, grateful.
