Opera built-in Ad blocker blocks other Adblockers?

  • Hi.
    The built-in Ad blocker of Opera Browser is too often mssing and seems to block addons. o_O

    On this site:
    https://www.duden.de/ueber_duden/wie-kommt-ein-wort-in-den-duden
    the activated Opera built in Adblocker (ObA) finds 2 ads but there are still ads to see. 😞
    This overrides my activated addon uMatrix, because when i deactivate an turn off the ObA all ads are luckily gone.

    Who can explain such behaviour?
    It has to be expected that no ads will be seen with activated ObA AND other adblocker addons

    thx

  • @cratte When you use, at the same time, two or more different programs (or, in this case, extensions) that do the same function, it's kinda expected that one will interfere with the other.

    I'll try, although in my system ObA finds 4 ads there and no ads remain visible. (Well, Ghostery removed some trackers too - I have not analyzed yet, how good is Opera tracker removal; they are usually not directly visible.)

    It is possible that linked site can detect some adblocking and serve some ads differently.
    It is possible that Opera adblocker has some whitelisting active (I have removed almost all exception from it) and lets different kinds of ads through.
    It is possible, that your uMatrix can block original ads, but somehow misses modified ones.
    All this is just guesswork.

    I have used ObA + Ghostery + Adblock for years, no big problems. Why Adblock at all, when I can add any adblock list to Opera? To allow easily exclude partial elements from some pages - all lists are unchecked in Adblock.
    Maybe using same lists by Opera and other tools can create some interferences.

  • @leocg that is also here my intention to say.
    But the problem is Opera made i guess.
    On most sites i remove the Opera built in Adblocker ObA because uMatrix and/or uBlock and/or Ghostery do it better and faster.
    Only 1 site is better for ObA, but i now can't remember it 🙂

    That ObA makes it worse in combination with same doing addons should not happen.
    This happens very seldom when activated more than one adblock addon.
    Maybe ObA is no real addon and reacts very different with addons?

    I always try all sites with all thinkable constellations with my adblocker addons to work clean and fast. 🙂

    ObA is not exactly an addon - from what I have read and understood, it doesn't work on javascript and extensions API level, but deeper (inside native code) and therefore should be faster too. I may be mistaken of course - only Opera devs can know that.

  • @donq ok, for me Operas Adblock overrides obviously installed addons.
    So it stands at first place in the analysis and manipulation of Data?

    I think to recognize different results of adblock addons in the order of installation.
    So it would be very helpful to manage the order of process of certain addons to see the differences. Like in a flowchart 🙂
