Firefox opens tabs randomly... but not in the way you'd think

This is a weird case, and I'm pretty sure it's not attributed to a virus.

Basically, I was playing full screen Starcraft whilst Firefox was running with multiple tabs open in the background. I alt-tabbed from the game to Firefox, and right clicked my taskbar and closed the game. As soon as I did this, a tab opened to Adtechus. (A legitimate AD company from what I can tell). I had a look on the website that was open when I alt tabbed before the new tab to Adtech opened and one of the ads on it had an Adtechus URL. The thing that perplexes me is that, my mouse didn't go near it, and so I couldnt have clicked it.

After this, a short while later, I re-opened the game, alt tabbed and before I could close it, another tab opened automatically from a site I was on before with a Facebook box implemented into it, and for some reason the new tab contained the Facebook "like" box seperate from everything else.

SEE HERE: http://www.facebook.com/plugins/likebox.ph...mp;header=false

Full website with the box to the left, here: http://www.gonintendo.com/

I can recreate this by right clicking the Facebook box on this specific website and choosing "This Frame > Open Frame in New Tab". But the thing is, I never did this in the first place! Plus, the website was already closed 20 seconds previously before this new tab popped up.

Then, automatically, another Adtechus tab popped up shortly after!


I am quite sure I have not got any viruses as I have a multi layered protection implemented on my computer and am concious of what I download/what websites I visit. This is not a regular occurance and has only happened today. Besides, these tabs opened from elements that were already on websites I had open, (ads, facebook "like" boxes) so it leads me to believe its something more cryptic?

I am also running noscript.

Thanks for your help. I would appreciate any and all replies.

As I said, the issue was a one time only thing. My main concern is, why did this happen?

Thanks for your reply and I look forward to any further help.

Probably a site that you had open was refreshing and it generated an ad to popup.

Also, Firefox can get a little buggy and do some weird stuff if you leave it open for too long. When memory usage starts creeping up over 300,000 KB, it's time to restart.

See here: http://kb.mozillazine.org/Memory_Leak

But yeah, since it only happened once, I wouldn't worry about it.

Consider adding Adblock Plus, though. Best Firefox addon ever! :huh:

It definately didnt refresh, and this site does not use popups.

First site with the ad was www.mmo-champion.com, a respected unofficial Blizzard community site. The second was www.Gonintendo.com, a Nintendo gaming based blog.

It was probably the gonintendo site that spawned the ad, since it has advertisements on the bottom.

Well I only opened Gonintendo after this happened, and the Adtech ads were on MMO-Champion, I'm sure. When I opened Gonintendo, I got that weird facebook thing where it auto-opened a tab with just the facebook box in it.

It's just so weird as to why this would occur. I mean, I alt tabbed from a game and close it, and an ad-tab launches. Should I be worried that it's a virus? I don't think I should be, and I've done multiple scans to prove as such. It's just something I can't figure out.
