Do you use any other add-ons that might interfere with ads? If none seem like logical candidates, you could paste your list of Extensions in a reply. To get a pasteable list, use Help > Troubleshooting Information then scroll down and select and copy the table following Extensions. (It might be hard to read, but should contain all the information.)

If you don't mind reinstalling the add-ons you use, you can reset your Firefox: http://v.gd/3SeMrx. You will not lose any of your data. Just the add-ons and any data they store.

Hi Antrikshy, you can post a link to the help page for Firefox reset this way:

or in other words:

Refresh Firefox - reset add-ons and settings

Hi i_see_dumb_people88, the Reset feature doesn't migrate any add-on settings. If you use an add-on that builds lists or saves content, you may want to make a backup before using Reset. See Back up and restore information in Firefox profiles for more on that.

Oh thanks. Also, you could have posted that as a reply to my comment instead of as a new "answer".

On this board I generally don't do that, but as a test this was started as a reply. Is anything different?

Hi i_see_dumb_people88, it appears you only have two Extensions installed and both of them are disabled. Is that correct if you compare this list:

orange Firefox button or classic Tools menu > Add-ons > Extensions

In that case, you do not have the AdBlock add-on. However, it's possible that ads are blocked in some other way, for example, your security software (if it has this feature) or domains you listed in the Windows hosts file (if you downloaded a hosts file or edited it manually).

If neither of those is applicable, they probably would affect other browsers as well as Firefox. Do you know whether the problem occurs in IE?
