Opera can't seem to find a way to fix their ad blocking for their mobile version. Their ad blocking sometimes works, and most of the time doesn't. Pop-ups and those that force to open an external app are freaking annoying and I don't understand why Opera can't block those. If your built-in ad blocker doesn't work properly please give us the option of adding an adblocking extension like Adguard. I truly hope that Opera can fix this and I hope they're trying.

I use opera gx for 3 months and yesterday on youtube it started to give adds. I reinstall opera gx and it didnt work I still get adds on youtube

@alex2293 Hi Alex and thanks for the tip.
I know I can install another adblocker and everything should be fine, that's what I did, but I prefer to have the integrated adblocker and not to use an external app. That's why I like Opera.
Hope they will fix this problem soon.

Don't know.

I use Android few time ago, and just tested Opera options recently.

@grgnd thank you for the support. Adguard filter support would indeed not only improve the built-in adblocker, but also make more people migrate from adblocking extensions. A win-win for Opera and the users imo.
