I have tried Avast secure browser before; its adblocker is near to Adblock plus, no more.
I have doubts regarding this ranking; Vivaldi is much better than Avast regarding adblocker.
The test was conducted in default settings, so I believe they're ranking Vivaldi based on that, but they did mention it could be improved by adding more filters. As for Avast, I think they paid to get a spot in the ranking.

I asked Brave Leo "What is the best privacy browser in the Middle East?" and it recommended "Kahf Browser," then I lost faith in its answers. 😞
I am back to Edge with uBOL, but I have noticed adding fliter list URL is now allowed as in Brave shield.

Most of you probably already know this bit of curiosity: the fellow who originally developed the Opera browser is the same fellow who developed the Vivaldi browser.

I am not sure if he's the same person, but I believe he was part of Opera team.
