Hello, Do you know if Google plans to add one this targeting options to Adwords : - Choose to target ads only by OS : MAC, Win,... - Choose to target ads only by browser : Firefox, IE,... This could be very useful for some niche. Example : Software Editors, Firefox Extension providers, ... Marketer looking for "geeks" or advanced internet users could target only firefox users.
I have heard no rumor that something like this is in the works but that doesn't mean that it isn't. I think you're wrong that only "geeks" and "advanced internet users" use Firefox. It's much more common than you may think.
