Description

UltraBlock is a powerful ad blocking and privacy extension built on Manifest V3. It removes ads, trackers and third-party cookies for maximum privacy protection and faster browsing. After cleaning the page, you see the same website but without the ads and invisible trackers that slow you down. UltraBlock blocks retargeting ads, video ads and hidden tracking services that monitor your online behavior. It works perfectly alongside AdBlock, Ghostery or Privacy Badger for an extra layer of protection. Use UltraBlock to: ★ Remove Ads, Trackers and Retargeting Scripts ★ Delete Third-Party Cookies Automatically ★ Protect Your Privacy and Online Identity ★ Speed Up Page Loads by Over 73 Percent ★ See Which Services Try are loaded in the Background ★ Manually Block or Allow Specific Services ★ See In Which Country Your Data Is Stored Ad and Tracker Database UltraBlock maintains a manually verified Ad and Tracker Intelligence Database with more than 5,400 hostnames. Each service is categorized as Advertising, Analytics, Social or Essential. Unnecessary services are blocked automatically, while essential ones remain active. Inside the UltraBlock popup you can see everything a site tries to load and decide for yourself what to allow or block. This gives you full control to customize your browsing experience exactly as you like it. Advanced Privacy Protection UltraBlock goes far beyond basic ad blocking. • Blocks over 80 percent of known ads and trackers • Cleans third-party cookies and browser cache after each visit • Sends the Do Not Track header with every request • Offers optional User-Agent rotation to make tracking harder • Lets you manually block or allow services from the popup • Prevents cross-site tracking and behavioral profiling This combination of automatic and manual protection makes UltraBlock one of the most complete privacy extensions available. Lightweight and Super Fast UltraBlock is efficient, quiet and fast. It runs smoothly in the background, improves page speed and reduces memory use. You get a cleaner, safer and faster web without extra effort. See Where Your Data Goes Open the UltraBlock popup to see exactly which services were blocked and where they store your data. You can temporarily pause UltraBlock to view all external services and their data locations, then turn protection back on instantly.

One bad issue: Too often when it's enabled on a website and I come back later, it's off for some reason. When I re-enable it, it doesn't remember the settings. It's day 2 and it's slow and doesn't come on. It's become unreliable to use. It doesn't allow to unblock FB, Instagram, Twitter. And one final point, the developer comments that this is a great extension without telling he's the developer until later he responds to another comment that a fix is in for the extension. Previous post: I like that I can individually toggle on/off all the different loaded trackers, ads, video players that populate a website. This ability isn't offered on nearly all blockers, so that is a good thing. It can be turned on/off on any website. It needs a manual element blocker to block ads.

Very poor extension complete scam..it redirects my page and shows me to reinstall and update chrome and i am using an older version i have , installed beta, and released version 5-6 times after rebooting , but after uninstalling this extension i got rid of that fake message.. such evil developers never faced such issue. have scanned my system with malware-bytes, hitmanpro, zemana.. and using bit-defender 2018.. really bad extension.. please don't consider that one star its not worth for that.. even the site it redirects to install chrome is fake

Does a good job, but finally after disabling it today I am no longer logged off of Facebook and others randomly. Apparently something in that extension is causing websites to log you off sometimes just a few minutes after logging in.
