Since Quantum updated (I'm running Windows10) an unwanted theme ('Dark by Mozilla') keeps spontaneously installing itself over other chosen themes ('Charlie Brown Thanksgiving' and 'All Fall by MaDonna' so far). I cannot remove the 'Dark by Mozilla' theme. It spontaneously installs even when disabled, and over themes that are enabled. When 'Dark by Mozilla' enables itself, I cannot read anything in the menu bar or task bar, and I cannot tell my tabs apart. Please allow 'Dark by Mozilla' to be uninstalled. I've tried loading a screen shot but it won't finish loading the file. I've already tried restarts, and clearing my cache, and neither of these have helped.

Just a note to add that this seems to happen in conjunction with 'Colorful Tabs'. Which is a pain, because I use colorful tabs quite a bit. If I disable 'Colorful Tabs', it doesn't seem to happen quite as much, or it automatically flexes to 'Light' instead of 'Dark'. I don't like having addons and extensions that I didn't personally decide to add. Thank you.

Hello, perhaps try VivaldiFox as a workaround? It's a pretty cool add-on, and close to Colorful Tabs: https://addons.mozilla.org/en-US/firefox/addon/vivaldifox/
