Serious Discussion AdGuard Browser Extension - General Discussions

@Bot Last question... in terms of privacy, which of the three is better and more effective: AdGuard, uBOL or Ghostery?

Bot cannot answer your question considering the maximum performance achievable by the various extensions.
I can.

1) AG
2) uBol
3) Ghostery

But this ranking is very partial.
Let me give you an example.

If we set the security/privacy performance of my uBoL (I have 19 DNR rules and one of these rules enables dynamic filtering in Hard Mode + TLD) at 100, your uBoL is at 25.

Have I effectively conveyed the idea?

So when I use my uBoL, I can even surpass another user who uses AG that is not set up like my AG.

I assume you fully understand what I wanted to write in these few lines.

Hey @Nunzio_77 and @Sampei.Nihira,

Thanks for chiming in, @Sampei.Nihira—that's a spot-on take, and I appreciate you sharing those details on uBOL's inner workings (and the Speedometer tip; I've run it myself and yeah, it's eye-opening how efficient it can be under the hood). Your point about customization making all the difference is key—it's not just about the extension out of the box, but how you tune it with rules, lists, or modes. That example with your 19 DNR rules + Hard Mode really drives it home; a maxed-out uBOL can absolutely punch above its weight and even outpace a default AdGuard setup in privacy blocking, depending on the sites you're hitting.

To build on that for @Nunzio_77: Sampei's ranking (AG > uBOL > Ghostery) aligns with what I've seen in tests, but as he said, it's "partial" without considering tweaks. For instance:
- AdGuard often starts strongest for broad privacy (trackers, fingerprinting, WebRTC, etc.), but if you don't optimize it (e.g., via Stealth Mode or custom filters), it might not hit its full potential—and the RAM hit could be a trade-off.
- uBOL is super flexible; adding those dynamic rules or lists like Sampei mentioned can make it a privacy beast without bogging down your system. If you're on a less powerful PC, this is where it shines, as you noted with the faster blocking.
- Ghostery is solid for tracker-focused privacy with its auto-updates, but it might lag a bit in immediacy or breadth unless you layer on more (though it's less customizable than the others).

Bottom line: Test and tweak based on your needs. If you share a bit about your current uBOL setup (e.g., which lists you're using), we could suggest ways to boost it toward that "100" level Sampei described. Or if you're curious about specific DNR rules, @Sampei.Nihira might have some gems to share. What do you think—gonna experiment with any custom rules in uBOL? 😊

Can you give me a detailed description of the three uBOL profiles:

Basic;

Optimal;

Complete

Which of the three do you suggest activating?
Hey @Nunzio_77,

Sure thing—happy to break down the three profiles (or "modes") in uBlock Origin Lite (uBOL). These are essentially pre-configured sets of filter lists and rules that determine how aggressively it blocks ads, trackers, and other annoyances. They're designed to let you choose based on your needs: lighter for performance, heavier for max protection. uBOL keeps things efficient under Manifest V3, so even the "Complete" mode isn't a huge resource hog like full uBlock Origin could be, but it does ramp up as you go from Basic to Complete. I'll describe each one step by step, based on how they work out of the box (you can tweak them further via custom lists or rules).

To access these: Click the uBOL icon, go to the settings gear, and look under "Filter lists" or the mode selector—it's straightforward to switch between them.

Basic Mode:
This is the default, entry-level setup aimed at minimalism and speed. It focuses on core ad blocking without much else, making it the lightest on resources (great for low-end PCs or if you just want quick, no-fuss protection).
- What it blocks: Primarily ads from popular lists like EasyList (which covers banners, pop-ups, and video ads on sites like YouTube). It includes some basic tracker blocking but nothing too aggressive.
- Key features/lists: EasyList, uBlock filters (basic), and maybe a couple of others for malware domains. No heavy privacy extras like anti-fingerprinting or annoyance filters.
- Pros: Super low RAM/CPU use (often under 20-50MB), fast page loads, and minimal breakage on sites. The block counter stays low and doesn't climb much on static pages.
- Cons: Misses some advanced trackers, social widgets, or cookie notices—privacy isn't as robust here. If a site uses sneaky tracking (e.g., via first-party scripts), it might slip through.
- Best for: Beginners, very weak hardware, or if you only care about ads and not deeper privacy.

Optimal Mode:
This is the sweet spot for most users—a balanced upgrade from Basic that adds more privacy-focused blocking without overdoing it. It's what the developer (Raymond Hill) recommends as the go-to for everyday browsing, as it enhances protection while keeping things efficient.
- What it blocks: Everything in Basic, plus better tracker prevention (e.g., analytics from Google, Facebook), some anti-fingerprinting rules, and light annoyance blocking (like cookie banners or self-promos). It uses more lists to catch things like telemetry and third-party requests.
- Key features/lists: EasyList, EasyPrivacy (for trackers), uBlock filters (extended), Peter Lowe's ad/tracking list, and a few others for malware and annoyances. Dynamic rules are more active here, which is why you might see the block counter gradually increase on pages like YouTube (as it catches background pings).
- Pros: Strong privacy boost (e.g., reduces IP leaks via trackers), good balance of speed and effectiveness, and low risk of site breakage. Resource use is still light (50-100MB typically), with quick blocking.
- Cons: Slightly more potential for false positives (e.g., blocking legit site elements), and the counter can climb higher than Basic due to proactive filtering.
- Best for: General users who want solid privacy without maxing out resources—especially if you're on a mid-range PC and value that "immediate" blocking you mentioned.

Complete Mode:
This is the full-throttle option for maximum coverage, pulling in every available filter list for comprehensive blocking. It's like turning uBOL into a privacy fortress, but it can be overkill and might require more manual whitelisting.
- What it blocks: All of the above, plus aggressive filtering for annoyances (cookie pop-ups, newsletters, social buttons), advanced trackers, malware, and even some cosmetic fixes (hiding empty ad spaces). It catches a ton of background requests, so counters can skyrocket on ad-heavy sites.
- Key features/lists: Everything from Optimal, plus Fanboy's Annoyance/Social lists, AdGuard-specific annoyances, URLHaus malware filters, and more regional/language-based ones. Dynamic filtering is at its peak, enabling things like hard mode for certain domains.
- Pros: Top-tier privacy and ad-free experience—great against fingerprinting, telemetry, and invasive tracking. If customized (like @Sampei.Nihira's setup with extra DNR rules), it can rival or beat AdGuard in effectiveness.
- Cons: Higher chance of breaking sites (e.g., videos not loading or login issues), slightly more resource use (100MB+), and the block counter will climb the most (as it actively scans for ongoing threats). Not ideal for weaker PCs without tweaks.
- Best for: Power users paranoid about privacy, or if you visit high-risk sites and don't mind occasional troubleshooting.

Which one do I suggest? I'd go with Optimal for you, based on what you've shared—it's a great middle ground that boosts privacy (addressing your earlier question about uBOL vs. AdGuard/Ghostery) without the RAM creep of AdGuard or the potential delays in Ghostery. Since you're on a less powerful PC and like uBOL's snappiness, Optimal keeps things light while adding those extra layers (like EasyPrivacy) to make it more effective than Basic. It's customizable too—if you want to push it toward Complete levels, you can manually enable a few more lists without switching modes.

That said, start with Optimal, browse your usual sites (YouTube included), and monitor the block counter/RAM via Chrome's Task Manager (Shift+Esc). If it feels too aggressive, drop to Basic; if you crave more, bump to Complete and add custom rules. Have you tried switching modes yet, or got any specific sites where privacy is a big concern? Let me know how it goes! 😊
 
Although custom filters require manual updates, it may be better to replace these filter lists, as with cookie blocking:

  • AdGuard Cookie Notices
  • AdGuard Other Annoyances

with these custom filter lists, which perform better:

  • uBlock filters – Cookie Notices
  • EasyList – Cookie Notices
Even with uBlock Origin, it's the same.

This is my uBOL setup with "full" filtering mode:

With great effort, I had ChatGPT5 generate this graph relating to uBo.
I apologize for the poor visibility, but I had to enlarge it.
Beyond the reference values, note how Hard Mode + TLDs allowed ranks well between Hard Mode and Easy Mode.
This graph was generated by specifying the blocking of the most at-risk TLDs + a series of other custom rules that limit privacy losses and fingerprinting.

In my opinion, with a certain degree of approximation, it can also be taken as valid for AG Browser Extension.

I will not make the same effort for a comparison between uBoL and AG Browser Extension,

because it exceeds my patience for interacting with A.I.;)
 
It's easy to add a filter list used with uBo to AG as well.
I'll show you how to do it with four images:

Click on the eye icon with your mouse:

After clicking with the mouse where I have placed the red arrow, you will have the RAW format:

Copy the link and then paste it into AG's custom filters:

Pay attention to the next image, which will tell you if the filter list cannot be inserted, or, as in the case of the filter list in my example, if it only has 540 rules.
On the other hand, in the filter list in uBo (first image), there are a total of 1618.
In this case, it is not a good idea to add this filter list because many rules are likely to be incompatible:

I hope this is useful to some users.;)

Interesting, in this latest version released today, AG also updates itself when the browser is first opened, just like uBo does.
I hope that the custom filter list updates will also follow this behaviour.

P.S.
The responsiveness of the extension also seems to have improved.

Do you think it feels faster and lighter?

It seems more responsive to me, so I can only assume that they have improved the service worker.
But of course, that's just a guess.

Even the automatic updates, which are not incremental as they are in uBo, and which occur even when you disable/re-enable the extension, contribute to making the extension more efficient, such as lists updated by default, compared to both uBo and, above all, uBoL.
I have, of course, verified this behavior myself.

P.S.

Now we just need to check whether the extension update coincides with the filter list updates or is separate, in the absence of information from the AG team.

How does minified privacy perform for you (did you disable Adguard privacy?)

If you meant the AdGuard Tracking Protection filter list in the AG browser extension, it is disabled because I have this filter list enabled at the DNS level.
The main reason is that it is updated more frequently.
But not all trackers can be blocked at the DNS level:

Trackers.png

That's why I added the custom EasyPrivacy (minified) filter list.

I also use 3 extensions alternately (uBo, UboL, AG), so I need to have an almost identical configuration in each extension.
