these are called admiral ads
they find a way to bypass this and show you the ad in a minimalistic way.
there's filter for it, no worry
uBO can read both ADP/AdGuard and some AdGuard Home snipplets.. not all but some
and what it can't read, it gives you a red marked word.
recently it's been glitchy even in fully supported Chromium browsers and that's thanks to Google
some functions been downgraded to make it compatible, hence why the real ones that supports it, gives you the direct option to add it via their third-party svr.
but even here it is the exact same story. FF on windows sucks recently
idk why... my frozen Win10 laptop runs a 2026 jan version and it's fine. I only had to disable eMudhra cert myself and that was it. I am perfect happy with Helium myself and if not, I'll go back to 147 Edge
