A lot of developers and “UX” “experts” really don’t appreciate how extreme these modals are. They disrupt everyone a little bit, and for less-technical users can throw them off entirely.
“Once per year” heh, add it to all the other disruptive shit they pop up and out on launch basically at random and they’re training users to dread launching the program. “Will it slap me in the face this time? If so, how hard?” Most modern programs have a problem with this, but FF is bad about it. And it’s just a fucking browser! Why? Why do this crap?
Thinking about it, most users probably don't care about what programs they use, having it pop up with a "Thanks for loving me" must've been a WTF moment.
Imagine if the calculator or stock app did that. Or the wrench in your toolbox...
