As of writing this review, Privacy Possum completely breaks embedded YouTube videos by causing them to give you a playback error.

Other than breaking websites, I didn't notice any significant changes while using this.

Extension has been Abandoned. Plus it still doesn't block your GPU identification from sites and more.

after installing this addon embedded YouTube videos are not playing

Makes surfing the web entirely unusable, couldn't figure out what was causing it, until I manually disabled every single addon and checked. Avoid.

Unable to move past the first page of a real estate website, or able to create a login or login after creating an account via an app. Have not come across any other websites I can't login to with this active

Это действительно очень хорошее расширение конфиденциальности. Мой личный опыт работы с этим расширением действительно хороший. Оно действительно сохраняет мою конфиденциальность и общие методы коммерческого отслеживания. Мне легко его использовать. Мне очень понравилось это расширение, и я рекомендую его всем.

A option for Whitelisting Domains would be great.

If I don't deactivate it, while adding a Tagpacker bookmark, the add-on window starts reloading infinitely. And on the "Privacy Possum" add-on window you can see how the numbers for "cookie" & "referer" sky rocketing within seconds.

Every Site except for the Tagpacker Homepage does not work with this add-on if you wanna keep Privacy Possum.
