How do I stop Firefox Pop-ups? They are eating up my data plan!

When out of town I use a MiFi with my phone, but Firefox has started its own pop-ups that I don't see (other than at bottom of screen) and as it downloads video and other streaming data, it is eating up my allowed data. How do I stop Firefox from opening a separate window with its pop-up in it? I have tried going back to an older version, but it is still happening, as it must be something within Firefox.

hello, pop-ups are usually a sign of adware or malware on your pc. please go to firefox > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the free version of malwarebytes & adwcleaner.

Remove a toolbar that has taken over your Firefox search or home page Troubleshoot Firefox issues caused by malware

also stay with the latest version available which will include all security fixes...
