Ad blockers usually block such stuff, for a good reason. But I don't mind it on a checkout page specifically though, because on a checkout page I wilfully disclose a ton of my private details, such as name, address, etc.
Good checkout pages work well with an ad blocker on.
The big deal was allegedly these small shops exposed you to viruses, but Walmart, Kroger, and Lowes did not.
Make it make sense.
Wasn’t Mozilla accused of selling data they collected from Firefox users?
Correct me if I’m wrong.
It's just the paradox of when you present yourself as "the good guys" - people will hold you extra accountable for things that others easily get away with as nobody expects them to do better.
Unfortunately, Mozilla tends to shoot themselves in their foot this way somewhat often.
If the page is too ad-ridden to tolerate, I may consider to just close that page, and go search for other options.
I use Firefox + uBlock Origin, because going to the wide commercial internet without some form of ad blocking is like going out without an umbrella when it's raining heavily.
