Best add-on that I can customize for every site I use.

Well said, and I agree 100% with the user's review below. I have supported (by monthly donation) the work by EFF for years, and I am about to restore it (new mop).

His/Her review:

"Privacy Badger is a must-have extension for anyone serious about protecting their privacy online. Developed by the Electronic Frontier Foundation, it's both trustworthy and effective. I really appreciate how it automatically learns to block invisible trackers without breaking websites, unlike some other blockers that need constant tweaking."

"The interface is clean and easy to use, and I love that it respects user autonomy—it doesn’t rely on predefined lists but intelligently reacts to tracking behavior. It runs quietly in the background, doing its job without slowing down my browsing experience."

"This is one of those rare add-ons that just works. Huge thanks to the EFF team for making a free, open-source tool that empowers users to take control of their data."

"Highly recommended!"

剛從肥滋滋的 Chrome 換到 Firefox，真的有種煥然一新的感覺。特別是裝上 PB 這款外掛後，體驗大大升級——比起一堆 Google 自家的工具，PB 不僅節省資源、加快網頁載入速度，更難得的是，它不是一刀切地封鎖所有廣告。雖然我不太清楚它判斷的邏輯，但它能夠適度保留「正常廣告」，甚至讓 YouTube 廣告如常播放，這種兼顧使用者體驗與網站營運的平衡，讓我非常欣賞。是一款兼具效率與彈性的防追蹤外掛，值得推薦！😘

Thanks!! :)

Greatfull for this :D
