Summary

Analyze keywords

This is the official development build of uBlock Origin.

uBlock Origin is NOT an "ad blocker": it is a wide-spectrum blocker -- which happens to be able to function as a mere "ad blocker". The default behavior of uBlock Origin when newly installed is to block ads, trackers and malware sites -- through EasyList, EasyPrivacy, Peter Lowe’s ad/tracking/malware servers, various lists of malware sites, and uBlock Origin's own filter lists.

The stable version of uBlock Origin is at: https://chrome.google.com/webstore/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm

Use this development build of uBlock Origin if you want to help test new fixes since last stable release version, and to help find regression bugs.

Report regression bugs at uBlock Origin issue tracker: https://github.com/uBlockOrigin/uBlock-issues/issues

"uBlock Origin Dev Build" does not share any settings with the stable release of "uBlock Origin", they are installed as two distinct extensions. If needed, use the backup/restore feature of uBlock Origin to transfer settings between the two extensions.

Hello, I hope you're having a splendid day! I am currently seeking opportunities to expand my business operations by investing in extensions with a significant user base, beginning from 50,000 users and up. No matter if your extension has a modest user base or counts its users in the millions, I am interested and ready to negotiate a purchase. If you are in possession of such an extension and looking to turn it into a profit, please consider reaching out to me. We can discuss the price and proceed with a transparent and secure transaction through a trusted escrow service based in the United States. It's great that Google allows the transfer of extension ownership between accounts, so your Google account ownership will remain intact. If you have any needs, please contact us via the following contacts Whatsapp: +1 (248) 896‑8035 Telegram: t.me/harryysandersonn
