Hi, thank you for your report! I've submitted a fix for the DDG and Qwant breakages. Can you please let me know what other sites are broken? I'd like to fix them.

The bug on DDG & Qwant were caused by the same issue (fixed here https://github.com/cowlicks/privacypossum/commit/15db4394af5a79e05b41b750fc23db8aa5b1ac3d )

You are correct about this being a browser wide thing, currently, we inject anti-fingerprinting scripts in every frame. There is a solution to this, but due to limitations in the browser extension api it may make the extension less effective in other ways. I'm currently looking into this. But for now, I've made the anti-fingerprinting code more robust to errors.

Thanks,
