Sometimes when I click in text fields (like to fill out a captcha), I get a pop-up ad and Firefox immediately switches to it, leaving the tab blank.
My problem is pretty much this, if I can explain it well enough: when I click on certain text fields, like to input the answer to a captcha, for instance, I constantly get pop-up ads and Firefox will switch to the pop-up, leaving the entire page that I was on before blank as if I opened a new tab.
This started a while ago and I'd been trying to just deal with it, but it's really starting to drive me up the wall. Is there a fix to this? I'm sure it happened when I went to about:config to try and fix something about text auto-filling. I can't say whether I did that right or wrong, considering my text doesn't autofill anymore, but now I have this annoying problem.
Help?!

Is there a setting in Firefox to display a pop-up ad when clicking a form field? I can't imagine...
I suspect a rogue add-on. Could you review your extensions on the following tab and disable ALL nonessential and unrecognized extensions. Then restart Firefox and test.
orange Firefox button (or Tools menu) > Add-ons > Extensions category
Any change?
Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
