This is the same browser you use to read “thousands of research papers”? And yet all that research hasn’t led you to an ad-blocking browser or add-on?
I use uBlock Origin. But the ads on some websites come through anyway. And I don’t have an ad blocker on my iPad.
The websites where I see Temu ads and so forth are not the same websites where I read research papers. It would be funny (but annoying) if a Temu ad popped up while I was reading the article “5-Formylcytosine mediated DNA-peptide cross-link induces predominantly semi-targeted mutations in both Escherichia coli and human cells” from the most recent issue of Journal of Biological Chemistry.
