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.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
