The 5 best free ad blockers & popup blockers Sublock Origin, AdBlock, AdBlock Plus, Stands Fair Adblocker, Ghostery, Opera Browser, Google Chrome, Microsoft Edge. This is an uncertain time for ad blockers, as the popular Chrome browser will need extensions to work with Manifest v3 starting next year. In January, Google may begin to disable support for Manifest v2 extensions on its Canary, Dev and Beta channels. By June, you could also turn off support on the main channel.
That would effectively affect current ad blockers, at least in Chrome. For its part, Mozilla, the manufacturer of Firefox, says that ad blockers that use Manifest v2 will work well in your browser. The application is designed to make browsing faster and safer by blocking ads, pop-ups, trackers and other online objects. Instead of blocking the content of a downloaded page, 1Blocker works with Safari's content blocking API to tell the browser what to block in advance, saving time and resources.
Adblock Plus is one of the old fashioned ad-blockers, and it's easy to understand why it's lasted so long. It's easy to use, free and effective. In our tests, it blocked most of the ads on the PCMag home page and got the second best score on a PCMag review page. Adblock also removed pre-published, windowed ads in the YouTube videos we tested.
It scores well on Adblock-Tester, but it didn't work well with Cover Your Tracker, a test that analyzes tracker blocking and browser fingerprints, specifically.
