^topic, I can no longer download any extension outside of the official firefox site.

I noticed yesterday when I created a new firefox profile that I couldn't download 3rd party extensions. This also affects my main profile and creating a new profile have the same issue. This is the error I'm getting: https://puu.sh/JqAIh/0854801832.png

I'm running Firefox Nighlty 108.0a1 (2022-11-01) (64-bit), windows 10 64bit professional OS.

Manually saving the plugin and drag and drop still works, but directly clicking download doesn't.

Any idea on how to fix this?
