UltraBlock - Privacy Protection & Adblock Extension

UltraBlock is a super fast Privacy protection and efficient Adblock extension using Manifest V3. UltraBlock removes all known Trackers, Ads and Third-Party cookies for maximum privacy protection. Remove retargeting ads, videos and block services that track your online behaviour. UltraBlock can be used together with the AdBlock, Ghostery or Privacy Badger extension. Use UltraBlock to:

★ Remove Trackers and (retargeting) Ads
★ Remove Third-Party Cookies
★ Protect your Privacy
★ Speed up your browser over 60%
★ See what services try to tracking you
★ See what services we prevented from loading
★ See in which country services store your personal data

Almost every website uses services like (retargeting) ad networks, analytics or social media buttons. Popular websites even load over 73 of these external services in the background. They do this to profile and track you with the goal to improve conversions or to sell your profile. You, as a visitor, do not need these services for the website to load or a good browsing experience. They only slow you down and compromise your privacy.

UltraBlock automatically blocks unnecessary services like ads, invisible trackers and third-party cookies. It shows what services are loaded in the background of the websites that you visit. UltraBlock makes websites load over 55% faster and keeps your privacy safe.

TRACKER DATABASE
UltraBlock maintains a manually checked tracker database with 5.471 hostnames of external services. These services are categorized into Advertising, Analytics, Social and Essential. Services that are not necessary for a good browsing experience are marked as 'unnecessary'. With this database UltraBlock automatically blocks ads and trackers that you do not need. UltraBlock shows you exactly what services are loaded in the background of the websites that you visit.

PRIVACY PROTECTION
UltraBlock protects your privacy in as many ways as possible. It starts by blocking content from services that are marked as 'unnecessary' in the UltraBlock tracker database. This immediately cleans out over 80% of trackers only leaving unknown or new trackers. To make sure even these can not track you UltraBlock cleans up the third-party cookies and your browser cache after every website visit. And finally, to make it even harder for services to track you UltraBlock randomizes your user-agent for each website visit.

LIGTHWEIGHT AND SUPER FAST
UltraBlock is a lightweight and super fast Chrome extension that runs quietly in the background. UltraBlock can be used by anyone who wants to protect privacy, make the browser run faster and also more secure.

SERVICE INITIATORS
When the publisher of a website installed Google Analytics the code is loaded directly via the HTML of the publisher. In other words the publishers website is the initiator of the Google Analytics script. But when a publisher installed a service like DoubleClick (Google product) then DoubleClick will also load: Google Syndication ,Google Static, 2MDN and sensic.net. In this case the initiator is DoubleClick and not the website of the publisher. When you open the UltraBlock pop-up and click on a service you'll see the label Initiator. This shows what the initiator of the service is. If a service was initiated by another service and not the website you're visiting we'll show an 'e' in front of the service in the service list.

SEE IN WHICH COUNTRY A SERVICE STORES YOUR DATA
If you open the Ultrablock popup, you can see in which countries the services that are loaded store your personal data. By temporarily pausing Ultrablock and allowing all services to load, you can see exactly which external services are loaded per website and in which country they store your personal data.

Bryce Pirie (ID: 000000950f4d95e4) Voted 5 ★ - Updated 09/14/2022 - edited edit: the latest update ( from September 14 2022 ) has almost completely fixed this extension, the main issue I've encountered is that the " block list " in the results area is not showing up. that said, everything else appears to be functioning just fine.( the settings / the website traffic monitor / the off and on function / and the auto-blocking " as is shown by the number on the pinned extension's icon. ).

jj (ID: 000000420a800d2c) Voted 5 ★ - Updated 08/20/2021 blocked ads that abp didn't. good for things like doubleclick, shady sites, etc. ultrablock is actually perfect for websites which require you to whitelist adblock plus, since ultrablock blocks the ads anyways but the website doesn't realize. definitely would recommend.
