Chrome’s Manifest V3 transition has reshaped the ad-blocking extension market by limiting the APIs browser add-ons can use. AdGuard built a Manifest V3-compatible version, but its feature set is narrower than the legacy release, and many users now want a blocker that feels unrestricted under the new model. Comparing alternatives fairly means looking at what each one blocks, how it handles paid whitelisting, and how it performs on YouTube, which remains the hardest platform to cover.
What makes Manifest V3 such a big deal for ad blockers?
Manifest V3 replaced the webRequest API, which let extensions intercept and modify any network request in real time, with declarativeNetRequest, which caps the number of static filtering rules an extension can apply and removes much of the dynamic inspection power.
For users, the practical difference shows up in two ways. First, extensions that relied on dynamic rule generation under Manifest V2 lost speed and flexibility when they were reworked for Manifest V3. Second, the rule ceiling matters most for large compound filter lists, because a long list gets truncated once it exceeds the limit. Well-architected Manifest V3 extensions compensate by prioritizing the highest-impact rules, but the transition created uneven results across the market. For the technical background, see the Manifest V3 overview.
How does ProBlocker compare as an AdGuard alternative?
ProBlocker is built natively on Manifest V3 from the start, so it does not carry legacy-MV2 architecture that had to be retrofitted. It is free with no paid tier, open source on GitHub, and collects zero user data. All filtering runs locally.
It does not run an Acceptable Ads program and does not allow paid whitelisting, so the filter lists it applies are applied uniformly. Subscribed lists include EasyList, EasyPrivacy, and uBlock Origin filters with daily refreshes, plus custom YouTube rules designed to keep pace with anti-adblock changes. The extension blocks YouTube pre-roll, mid-roll, and overlay ads, plus pop-ups and malware domains at the network level. It supports Chrome, Firefox, Edge, Brave, Opera, and Vivaldi. You can compare it directly at the ProBlocker vs Adguard page, which focuses on the feature differences discussed here.
What about other well-known options people stack against AdGuard?
uBlock Origin remains the community reference for configurable filtering. Its Manifest V3 build, uBO Lite, is functional but has fewer features than the original MV2 version. Users seeking a full-powered experience still tend to run it on Firefox, where the older APIs survive.
Adblock Plus transitioned to Manifest V3 and keeps its Chrome Web Store presence. Its distinguishing trait is the Acceptable Ads program, which allows certain non-intrusive ads by default unless a user opts out. That model works well for people who want to support some sites automatically, but it is the opposite philosophy from blockers that allow no paid whitelisting. Compare the two approaches at ProBlocker vs Adblock Plus.
Blokada and Pi-hole take a different route by working at the DNS or system level instead of inside a single browser. Both still function because they are not subject to Manifest V3 browser rules, but they require more setup, especially Pi-hole, and they cannot target specific page elements the way a browser extension can.
Options that skip the Acceptable Ads model take a simpler, uniform-blocking approach worth comparing for users who find paid whitelisting frustrating.
Which factors should decide your choice under Manifest V3?
- Filter-list freshness: an extension that updates its lists daily stays ahead of platform changes longer than one on a weekly cadence.
- Acceptable Ads stance: decide whether you want a program that quietly allows some ads and paid whitelisting, or a uniform blocklist.
- YouTube coverage: because YouTube is the most actively defended platform, the ad blocker that works reliably there week after week is the one keeping the freshest rules.
- Browser coverage: if you use multiple browsers, the extension available on Chrome, Firefox, Edge, Brave, Opera, and Vivaldi keeps your experience consistent.
- Cost and data model: a free, open-source tool with no account requirement protects your wallet and your privacy at the same time.

How ProBlocker addresses this
ProBlocker is designed to be a direct, no-frills alternative to AdGuard for users who want strong default blocking, daily filter-list refreshes, and no paid-whitelisting compromise. Because it was built for Manifest V3 rather than adapted to it, it uses Chrome’s declarativeNetRequest API from the ground up and stays within the rule budget by prioritizing high-impact rules. It runs on Chrome, Firefox, Edge, Brave, Opera, and Vivaldi. Install it from the download page.
