uBlock Origin Extension

IMPORTANT: uBlock Origin is completely unrelated to the site \"ublock.org\".

uBlock Origin is not an \"ad blocker\", it's a wide-spectrum content blocker with CPU and memory efficiency as a primary feature.

***

Out of the box, these lists of filters are loaded and enforced:

- uBlock Origin filter lists
- EasyList (ads)
- EasyPrivacy (tracking)
- Peter Lowe’s Ad server list (ads and tracking)
- Online Malicious URL Blocklist

More lists are available for you to select if you wish:

- Annoyances (cookie warnings, overlays, etc.)
- hosts-based lists
- And many others

Additionally, you can point-and-click to block JavaScript locally or globally, create your own global or local rules to override entries from filter lists, and many more advanced features.

***

Free.
Open source with public license (GPLv3)
For users by users.

If ever you really do want to contribute something, think about the people working hard to maintain the filter lists you are using, which were made available to use by all for free.

Saint Esprit & Co (ID: 0000004b3bb2a2e2) Voted 5 ★ - Updated 12/06/2024 Just today in France, Youtube found a way to block Ublock by not allowing video for more than one 59 seconds, after that, loading endlessly... Hoping for a quick solution with an update ^^

Laurence Gough (ID: 0000009cbea8e4f1) Voted 5 ★ - Updated 12/02/2024 Best Chrome extension around. When this stops working, hello Firefox!

_ (ID: 0000002f5080500c) Voted 2 ★ - Updated 11/26/2024 追記 2024/10/15現在、uBlock Originがいずれ使えなくなることが確定したので、uBlock Origin liteかEdge アドオンのuBlock Originに移行推奨します。 gliastudioの目障りでうっとおしい動画広告が要素ブロックでも遮断できない ↑ページのソース表示からgliastudio広告と思われるソースを虱潰しに特定してマイフィルターにぶち込んだら、消すことが出来ました。(その場合、音声の消し忘れにご注意を)

̨ ̨ (ID: 000000ad331ec748) Voted 5 ★ - Updated 11/05/2024

(ID: ) Voted 5 ★ - Updated 10/20/2024 uBlock Origin is simply the best. A must have for human kind.
