I use Safari on my MacBook and I have checked the “Block Pop-Up Windows” under the Safari heading on the toobar. So how can ‘zeda’ (or something like that) blast through?
Sites or advertisers living from those Pop-ups are always on the run to get views and therefor constantly develop their code to bypass Pop-up blockers. Obviously this means they put a lot of focus in working around blockers shipping with browsers.
You may be able to block Pop-ups more reliable using some Anti Pop-up plugin or something like Adblock.
