I don't know, Brave says it's every third new tab. https://brave.com/brave-ads/browser/

Looks like I'm getting a ProtonMail ad every few new tabs. I never noticed because I've never looked at the new tab page. Doesn't noticeably slow it down to have the ad there, luckily.

So, to reiterate: Brave is adware.

The new tab ads can be disabled with 2 clicks.

I love how quickly the goalpost moves from "No ads" to "Only opt in ads" to "Ads can be disabled with two clicks."

Quit coping and just admit it, Brave is adware. If you like it, that's cool, totally your choice. It's fast, performant adware. But it's adware all the same.

Firefox has ads in the same places.

whataboutism gets you nowhere. Brave is still adware.

As is Firefox, and Chrome.

So really, there's no point in singling it out.

It's strange you're so adamant to label Brave adware while dismissing concerns that Firefox engages in very similar "adware" practices.

It might be adware but I’ve actually never noticed the ads!

Also it’s the only browser on my phone that I can use to browse the web without ads…

When we're talking about reasons to switch browsers, then saying they both have the same behavior is not whataboutism. It's extremely important context to the complaint.
