I haven’t seen a single ad since the moment I installed Firefox and clicked “don’t suggest stuff”.
Safari practically never does that shit, which is one of the reasons I prefer it on platforms where it's available. IDK why modern Firefox is so damn eager to interrupt me. Just open a window with my last session or my default tab and shut up. I don't care if you just updated. I don't care if you're weirdly-enthusiastic about introducing me to a feature that hasn't been novel in a browser in at least a couple decades (color themes—LOL, that was just embarrassing). I certainly don't want an actual advertisement. And for god's sake, no, I still don't care about Pocket, and I never will.
For less-technical users, this stuff isn't just annoying, it can disrupt their entire browsing session. "Wait... where's my email? Is it gone? Is this the right program?" Firefox (and other teams that do crap like this, in their products) should knock it off. It is not OK.
Yes, I am willing to pay say 100$/year for web browser if money would entirely go to development. Maybe something to support staff like CEO. But not over 5 000 000 per year ( see https://en.wikipedia.org/wiki/Mitchell_Baker#Negative_salary... )
And if such browser would be actually user-first, without ads for VPN and Disney movies (especially without ads pretending to not be ads).
Then it appears they recently added an additional sponsored option, and defaulted it to enabled, in an update, even for users like myself who had every other sponsored option disabled.
They're hardly the only organization that does this, but it is extremely disappointing. Were Firefox not the only major browser with very useful extensions, I'd certainly switch to something else.
