No, actually, they don't say that. They very clearly say that they don't (and don't believe most people will) consider what they are doing "selling your data", but that it may legally considered selling your data in some countries.

For example, Firefox runs ads using your language and city/country (on the default new tab page) - but no other data. I think the vast majority people would fine with the privacy implications of that, but this may be legally considered selling your data.

Being specific about what types of data they collect and how they use it is actually far superior to some nebulous promise that has no definition.
