Sorry, but you didn't get that from the official Mozilla website.

Firefox any version for Windows, Mac OSX and Linux from mozilla.org only come with well Firefox and not any extras including what you claim. The only thing that got added of sorts in last while was the OpenH264 Video Codec plugin. Firefox is sadly becoming of the the increasingly fewer things that does not get bundled with any extra crap. Just because you see it in Firefox does not mean it comes with the Firefox download or update from mozilla.org. It could have been added by a Extension install or update (as this can happen with extensions from out side of the addons.mozilla.org host) or by a recent software install or update for example. Or you may be infected and the tools you used has not dealt with it yet. Some sites like download .com aka cnet is a known adware site and often times uses their own installer to add extra stuff to otherwise clean sotware. ________ Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
