Popups? In my Firefox?

It's more likely than you think!



And that's just one of the work-safe ones. (The dating site ones are vile.)

Any idea what could be causing them? I could post a screencap of running applications if that helps, but I didn't recognize anything out of the ordinary.

You should also mention whether you've already done the above, whether the pop-ups only come up when you're browsing or whether they pop-up without you already using Firefox.

Nothing there, and they seem to only happen when I use Firefox.

Not all the time, either. Just at random, they spring up like wildfire.

Any special sites you know causing it?

Visiting pr0n or 4chan sites may cause this, no matter how well protected you are.

cj iwakura

I don't visit the former, and I avoid the latter for the most part.

The only place I can think of that seems likely to cause them would be a doujin(re: fanmade shmups) website.

Still, it's off and on. There's none at the moment, but they seem to spring up like wildfire in the evening.

Get one of many add-ons that block pop-ups. There's a ton out there.

It could also some crap running in the background!

An app that looks for a browser to run and if one is found then shoots of requests for web pages through your OS. The OS then passes them on to you default browser and depending on settings that makes Firefox open new windows. No magic just adware or maybe something worse.

Yeah, I'd definitely recommend NoScript and maybe AdBlock Plus at the very least.

And to expand on what BlindZenDriver said, you should get hijackthis and see what it turns up. Task manager is almost worthless now that most threats will mask themselves as services, or bury themselves in system32.

A software firewall, some adware/spyware removal, and an anti-virus program couldn't hurt either.

Definitely sounds like a separate program launching web sites via your default browser, which happens to be Firefox.

Run Hijackthis or AdAware and see if anything pops up.
