Does Firefox use advertising pop-ups for revenue?

I am thinking about installing Firefox but, I don't believe in a "free" lunch. Ergo my question. How can Mozilla "give away" Firefox? Is it supported by pop-up advertising or sale of accumulated browsing data?

This happened

Not sure how often

User Agent

Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C)

The only popup advertising you get that overrides popup blocking is from malicious software already installed on your system hijacking your browser. This targets all browsers, not just Firefox.

How do we know this? The popups never happen on non-windows Operating Systems where the malware doesn't exist.

I have popups disabled, but I get them all the time and they are annoying as hell! I also invariably get a popup ad on my desktop when I exit Firefox.

No, Firefox is run by Mozilla which is separated into a non-profit foundation and a corporation, the latter receives a percentage of Google's revenue from search result click-throughs via the specific Google default in Firefox's search bar. Installing the Adblock plus extension so no ads are visible on google search result pages or just changing to a different google search will mean Mozilla gets nothing.

Dear Mozilla er I mean "AnonymousUse", No..it's Firefox advertizing. How do "we" know this? The popups only happen on Firefox, not AOL, not IE, or any other Windows operating Systems.
