Yesterday, the Tor Project announced that it will be teaming up with Mozilla, the maker of the Firefox browser, and the Center of Democracy & Technology, an advocacy group for digital rights, as part of a new initiative called Polaris. The partnership helps both Mozilla and Tor. The Firefox browser will get more privacy features while the Tor Project will get to work with Mozilla engineers to help work on the Firefox codebase and get increased Tor network support. The Tor browser is built upon Mozilla technology.
