Also I forgot. You have to make sure chromes pepper flash is disabled if you are using Chrome, that is not Chromium

I disabled my UA extension and Pepper Flash in Chrome. When I try to load an Amazon video, I get an error screen that says "Flash Player is not installed". When I hit F5 to reload the page, I get the same error.

When I enable my UA extension (with Pepper Flash disabled), I still get the same error screen but reloading with F5 causes the video to load correctly with pipelight. This tells me that the addon's built-in UA isn't kicking in. I'm guessing this is why ScriptorDE added that Linux/pipelight switch in his settings. Wish I could help more but python is one language I know nothing about.
