I think focusing on the right vs. left continuum both detracts from any good that Mozilla desires through their contribution. To be more specific, I think this continuum is actually too restrictive, misleading, and not a sufficiently accurate representation of the political views of individuals and organizations.
In my opinion, the best model that I have seen for discussing politics actually focuses on the expansion or contraction of freedoms across the three dimensions: personal, economic, and political. By focusing on policies, we avoid using labels to describe one another, and evaluate actions based on outcomes (both consequences and outcomes). In this model, more freedom along an axis is not necessarily a good thing if it results in a loss of freedom along another axis e.g. slavery could be described as an economic freedom of one demographic to restrict the personal freedoms of another. Through this lens, Mozilla might be funding a cause that they believe preserves personal freedoms of all individuals against the encroaching economic freedoms of corporations with respect to computer security, privacy, and whatever other choices an individual can make in the growing digital world, which is consistent with my understanding of Mozilla's stated mission.

This model is not of my making; I came across it here: https://www.nationstates.net/page=create_nation , and I find it very surprising that model came from what is essentially an author's conception and implementation of a game: https://en.wikipedia.org/wiki/NationStates .
