Hi! I updated my browser and ever since then I can't re-enable any of my themes. Even when they say "Enabled", nothing happens. The only ones that work are the light and dark theme as well as another one of the Firefox themes. I tried going on the users' pages and downloading them again, and also tried downloading new ones. Neither of these things worked. I am basically just asking how to re-enable my themes and extensions so that I can customize my browser. Thank you! :)
