Try here:

orange Firefox button or Tools menu > Options > Content

Uncheck the first box.

Note that some toolbars also might have a pop-up blocker (e.g., McAfee) so you might have to check those, too, if the site still doesn't work.

I don't have a reply, I need help!

Open Firefox -> go to Tools Menu -> Options -> Content -> Remove Checkmark from "Block Pop-up Windows"

OR

if you want to just Disable Pop-up Blocker from specific websites, follow these steps.

Open Firefox -> go to Tools Menu -> Options -> Content -> Checkmark on "Block Pop-up Windows" -> Click "Exceptions..." button infront of "Block Pop-up Windows"

-> Type the addresses of those specific websites one by one e.g. www.yahoo.com -> Click Allow -> click Close on "Allowed Sites - Pop-ups" window -> click OK on Options main window

Check and tell if its working.

So I go to my Tools menu > Options >Content & just Uncheck the first box? Is that right?

Hold on I am writing all this down.

OK I got it all written down, by the way I can see the Tools menu from right here, shall I go into Tools first or open Firefox?

yeah man go to Tools Menu ....

jscher2000 are you still there?

The Options dialog is inside Firefox. As noted above, the exact path to get there depends on whether you have the orange Firefox button or the classic menu bar.

OK gentlemen, I think that took care of my problem, thank you so much.

You probably will want to turn the pop-up blocker back on when you're done with that site. :-)
