@fat8893 said in Built-in adBlocker has turned off, but website claiming adBlocker in use:

...
To answer regarding extensions, I only have IDM Integration Module, Opera's Install Chrome Extensions and Windscribe, and that's all. But even so, Windscribe is not turned on at the time of this writing.

I wonder about the nature of Windscribe - whether it makes certain changes to the browser/system that are not fully "backed out" by merely turning it off. If those changes are detectable by website 'sniffing', then it could create an ad-blocking/user-location problem.

Okay, now I know the cause of the problem: It's Windscribe!

Even if its VPN is turned off and not running, its own adblocker is still running. I have to manually select "Allow Ads" from the extension's option. Now it's working fine.

Took me a while to spot the problem.

Yes, the adblocker symbol is only visible if the adblocker is switched on in Setttings.

In your screenshot I see a "strange" triangle next to the Bookmarks heart.

Is your adblocker switched on in Settings?

That "strange" triangle next to Bookmarks heart on the address bar? That was "Send to My Flow" icon.

Nope, I didn't switch on the adblocker in Settings.

I visited the "real" KissAnime website with the Opera adblocker on: 21 adds blocked.

Then I switched off the Opera adblocker: video works OK.

So maybe you have an adblocker extension or those pages are blocking Opera.

@fat8893 As noted by @lapsang, the KissAnime site they list also works without adblock complaint problems here (with my third-party cookies disabled and Windows Defender security). With the OnMSFT site, an adblock complaint does pop up after a few seconds in Opera; with an Edge browser, there's no adblock complaint for OnMSFT. In any case, the complaint popup offers a click-text to bypass the complaint popup, as well as suggesting whitelisting. I'm not sure what is causing your Opera to behave differently than ours with regard to the KissAnime site, unless you're seeing it at some subpage within the site that we haven't gone.

Are you using any extensions with Opera? If so, which ones?

When I visit KissAnime with the Opera adblocker on, there is no problem at all.

Is it this website?

Btw, I had tried to play the same anime movie using the website you linked and ummm...

OnMSFT asks whitelisting.

Can you do that? (Does it work?).

I tried to whitelist OnMSFT. But unfortunately, I couldn't even find the blue shield icon on the right side of the address bar, as instructed.

When I visit KissAnime with the Opera adblocker on, there is no problem at all.

Is it this website?

Nope, not that one. This one with different domain. I'm using Persona 3 Movie #1 as an example.

Is it this website?

@fat8893 1. Is there a particular site that can serve as an example of where you see the problem?
2. Have you disabled site cookies or 3rd-party cookies in Opera? (O > Settings > Advanced > Privacy & Security > Content Settings > Cookies > is "Allow sites to save and read cookie data..." enabled? Is "Block third-party cookies" disabled? Are there any sites listed under "Block"?)
3. Are you using any kind of custom hosts file in your Windows installation?
4. What anti-malware/antivirus programs are you using?

1. I always see the problem whenever I'm accessing KissAnime and OnMSFT.

2. I have enabled cookie data. I disabled third-party cookie. No sites whatsoever under "Block".

3. I'm definitely not familiar with custom hosts file. In fact, I never tamper with Windows installation or the OS itself whatsoever.

4. Currently only using Windows Security.

The problem happens in Opera 57?

Just updated my Opera browser to the latest version of Opera 57, but the problem still persist.

@fat8893
and if you delete cookies of the website and empty the cache?

Yes. Even when I delete all of my browsing history and cookies before closing the browser, the problem is still there.
