Mozilla have 10 guiding principles. Among them is the concept of free and open source software. This means that the computer code which makes programs work is made publicly available so that anybody who sees it can make modifications or suggest improvements. This transparent approach is part of what has made Mozilla so popular among internet users. On top of this, transparency has helped to cultivate an atmosphere of trust and community.

This feeling of trust and openness, along with Mozilla’s emphasis on privacy and security has led to Firefox becoming the browser of choice for tech-savvy users and people with internet privacy concerns. The sheer volume of available modifications and add-ons has also helped to secure this enviable position in the market.


Recently however, The Mozilla Corporation has been mired in controversy over the appointment of Brendan Eich as CEO in March of this year. Eich had made a political donation to a campaign against same-sex marriage in California in 2008. This had sparked controversy in 2012 when it was first discovered, but with Eich’s appointment in 2014 as CEO – Mozilla again came under fire. While this was damaging to Mozilla’s reputation, it did not constitute a security threat.

They are volunteers who help to contribute bug fixes and language translations of Mozilla products, and ultimately, contribute to Mozilla’s success.
