What do you think of something like [this](https://addons.mozilla.org/en-US/firefox/addon/user-agent-string-switcher/)? It seems recommended by Mozilla. And spoofs usear agent on JS level too (according to developer). I tested, and it indeed do not trigger any Cloudflare spoof detection in opposite to `about:config`

approach.

I mean is it safe to use something similar? Because it really helps (especially on mobile Firefox) to get away from “install our app” pesky notices, if I spoof windows PC (I do not have any windows machine, if it is important)
