All my installed styles keep disappearing
Hi! I have a little problem: ever since Stylish got updated, all the styles that I have installed disappear every time I close Firefox and Stylish tells me I haven't installed any styles. I keep reinstalling them and as soon as I close Firefox they're gone again. I really really want to keep my installed styles because I think youtube looks much better with them and I can't bear youtube's bright colours and everything, but I also don't want to reinstall and re-edit all the styles every time I turn on my computer. I tried uninstalling stylish and reinstalling it, but it didn't work. Does anyone have the same problem and does anyone know how to solve this?
