Please consider turning on send info to Mozilla before posting a question. This helps us help you.

for Safe Browsing : part of a Mozilla experiment, called 'Shield Studies'. Without even knowing it, you may have volunteered for this Mozilla experiment. Would you go to : Options => Privacy & Security => under 'Data Collection and Use' : Did you uncheck : 'Allow Firefox to install and run studies ' or is it checked  ?

To check if you are enrolled in these studies : Type in the address bar about:studies

Any extensions that you see listed there, you can either disable or remove, just like this Safe Browsing version 4 (at the end of the experiment they will be disabled anyway). See for further information : https://support.mozilla.org/en-US/kb/shield

For your popup Note you may have to google the programs as some of the addresses have changed. Save the Reports. Google everything as you do not want to delete registry keys that are needed for some programs that are ok but stick a url in to buy program. https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware and https://www.malwarebytes.com/adwcleaner/ and https://forums.malwarebytes.com/topic/9573-im-infected-what-do-i-do-now/ Note post in 1 forum only and wait.

Thanks for your response, Phshadow. Yes, the 'Allow Firefox to Install and Run Studies' option was checked. I have since unchecked this option and removed the Safe Browsing add-on. However, this has not solved my problem. I still receive the same pop-up message as before. I am not being requested to buy any program and the only 'program' indicated is the Firefox Software Updater.

We do not have a pop up that does this. I directed you to run the scans with the url's provided. The results should find it.

The only thing that ever may come up is the Help then About Window asking to to restart because it has already updated..

Your A/V will not, you must use Malware scanners. ASAP

Please let us know if this solved your issue or if need further assistance.

You indicated 'we do not have a pop up that does this'. I have to point out I opened the details about the request, and it indicates the certificate comes from Mozilla Corporation.

Great If you run across it again take a screen shot of it and post it.

Thanks
