A site I visit produces pop-ups and I decided to look into why. I discovered that my Chrome already disallowed pop-ups (Settings > Show advanced settings > Privacy > Content Settings > Pop-ups), so what was going on?
I didn't find many pages on this particular problem via a general search, except for this forum:
The advice there was that if Chrome's normal pop=up blocker did not work, the issue probably was malware. I was not quick to this probability.
The other advice (as above) was to install Adblock and/or Flashbock. They take care of different problems, in my opinion, and I was not satisfied.
I decided to take matters into my own hands and figured there surely must be a pop-up blocking add-on to supplement Chrome's faulty one. At the Chrome store (I think that's where it was... lots of clicking around, you know), where it allows one to "shop" for other extensions, I typed in the keywords "pop-up blocker," and nothing of relevance came up. (Ditto for simply "pop-up" and also for "blocker." Boy, Chrome's built in pop-up blocker must have been perfect, if there were no such extensions developed anywhere.)
Before giving up, I gave it a shot on a regular Google search, and there was... "Better Pop-up blocker":
Since I already installed "Better Pop-up blocker" and didn't have a chance to research whether any of the others might be potentially better, I'll first see how it goes. The developer took the time to address questions at the program's web site (at least in 2010)…
... And that made me think he was at least down-to-earth, giving me a false sense of confidence in the product. I just tested it once, and "Better Pop-up blocker" did take care of the pop-ups of the site I regularly visit. We shall see how well it behaves, otherwise... what;s next on that list above? "Classic Popup Blocker"!
