I have Fedora 34.
I am trying to install the User Themes extension.
Whenever I go to the website and move the slider to “On”, when I refresh the page the slider is back to “Off” again.
I also installed the “Extensions” app, and I can find the “User Themes” under the “Manually Installed” section. On the “Extensions” app clicking on the slider does nothing, absolutely nothing.
I cannot activate this extension.
