You posted using an iPhone, but your post ended up the category of Firefox for Android... is this actually a problem on a desktop/laptop computer? If so, what operating system is it running?

I will assume Windows...

Random popups, meaning ones that aren't specifically related to a page but can appear at various times, may be caused by a bad add-on. Here's my suggested procedure for tracking down and cleaning up bad add-ons and other ad injectors. Sorry for the length -- it's not as bad as it sounds:

(1) Open the Windows Control Panel, Uninstall a Program (on XP: Add/Remove Programs). After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help in smoking out undisclosed bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here.

(2) Open Firefox's Add-ons page using either:

• Ctrl+Shift+a
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Plugins. Set nonessential and unrecognized plugins to "Never Activate".

In the left column, click Extensions. Then, if in doubt, disable (or Remove, if possible) unrecognized and unwanted extensions.

Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Any improvement?

(3) You can search for remaining issues with the scanning/cleaning tools listed in our support article: Troubleshoot Firefox issues caused by malware. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.

Success?

Hi Laban1, I don't know if there is an equivalent of #1 on my list for Mac, so perhaps go straight to #2.
