I'm pretty sure this has nothing to do with browsers (and just for reference, I'm not using mozilla or firebird anymore)
I was just querying what problem, as I see no where in the thread you mention a specific problem (other than the one the thread is about obviously), if it's just that the ads aren't related to the site (ie: being tech related), then I see no problem at all, we all have lives outside of the site/internet/computers and I see there being no harm in advertisers choosing to reflect this in advertisements.
