Sorry but it's abandoned. Will 5-star after updates.

This addon breaks purchasing games on epic games store.

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.

Disables YouTube videos in Reddit.

Not effective against modern tracking methods

I keep getting facebook ads related to other websites i visit. this is the only reason i got this, and it does nothing.

Great extension, which unfortunately seems to be discontinued (check its Github, no updates in a while, and related conversations in issues tab). Now breaks embedded Youtube videos.

Development has stopped. Many open issues since the beginning of 2019: https://github.com/cowlicks/privacypossum/issues Probably just use uBlock Origin, Privacy Badger and Firefox built in strict tracking setting.

The development has stopped, it's abandonware

this hasn't been maintained in a while, meanwhile many sites are broken while using it. I've switched back to privacy badger and reported this add on for breaking sites.

It bracks https://m.webtoons.com/en/drama/the-weight-of-our-sky/ep-3/comment?title_no=1739&episode_no=3 and other webtoon sites like webtoons.com
(Sorry for bad en)

Works but I will not adjust this review until

IT STOPS OPENING AN ANNOYING POP UP WHEN I SYNC MY ACCOUNT TO A NEW INSTANCE OF FIREFOX. STOP DOING THAT, ITS ANNOYING
