The warning still shows up :/
@Piter432
take screenshot --> https://github.com/reek/anti-adblock-killer/wiki/Report-Guide
Here you are:

I have the latest uBlock Origin, newest Anti-Adblock killer filters list version, latest Tampermonkey for Chrome and latest version of Anti-Adblock killer userscript. Only Chrome isn't newest, because I'm now on Windows XP.
Try add this ==>

@MajkiIT: Still doesn't work :/
@bourne9: LOL. It's not just me. The same is on my mom's laptop, which have... Windows 7 64-bit on Firefox with newest Greasemonkey Anti-Adblock killer filters list and userscript :)
@bourne9: Ah, I'm not sure you see that on my screenshot, but my GPU will die soon and I don't have money to buy completely new & powerful PC, because it's expensive in Poland and my current PC needs almost (new HDD's can be not included in my new PC) full new components. Unless you want to buy new PC for me, lol :v
@bourne9:
I didn't mention new PC
But your comment sounded like that.
just download Windows 7 from torrents and run a clean installation.
I hate cracking and pirating, so no. I WILL NOT crack Windows 7 and even any other paid OS for PC. Also, I don't have powerful internet, so downloading a file, which its size have some GB isn't an option, especially when because of my GPU state, my PC can show BSoD.
Secondly, my PC is 11 years old and still runs like a horse with Windows 10
Yea, yea. And some people have problems with Windows 10 on PCs similiar to yours. I will not experiment with OS on my one and only one PC.
please don't make excuses of a dead PC
Do you want to show you my specifications of PC? :) Also, I'm IT geek so I NEED a good PC and that's why I wrote about new PC.
if you wanted Windows 7 you could have installed it
Yes, I could. But in those times I didn't know almost the same of the IT as today, especially I was younger.
You don't need a new PC, you need a new OS
I NEED a new PC. Why? I wrote that earlier. Read carefully, because I don't want to say the same many times.
simple as that
So, if you think that my situation is simple, come to me. We'll see, what you will tell then :)
I saw your screenshot, but this issue has nothing to do with your GPU or any hardware, so why are you even bringing that up in the first place ?
Lel, I think you don't know what are you writing about. I wrote that the STRANGE LOOK of MY SCREENSHOT is because of MY GPU, and not that because of this issue is something wrong with my GPU as you can see on my screenshot. Please read with understanding, dude.
