You can even skim our notes describing <a href=\"https:\/\/www.mozilla.org\/firefox\/releasenotes\/?utm_source=blog.mozilla.org&#038;utm_campaign=firefox_frontier&#038;utm_medium=referral\">What\u2019s New<\/a>.

Did you even know you have user rights? With Firefox, you do. They include rights under the Mozilla Public License, which gives you lots of freedom to use, copy and share Firefox as much as you want.<\/p>\n<p>Speaking of licenses, you can also learn about allllll the Licenses (there are many), read allllll the definitions, and get access to the FAQs. (Spoiler alert: just about everything is free and <a href=\"https:\/\/developer.mozilla.org\/en-US\/docs\/Mozilla\/Developer_guide\/Source_Code\/Mercurial\">open source<\/a>).<\/p>\n<p>And perhaps coolest of all, you can check out the hundreds of thousands of people who have contributed code to Firefox. Because our contributors are <a href=\"https:\/\/www.mozilla.org\/credits\/\">listed by name<\/a>. If you\u2019re in San Francisco you can also look at all these names on the <a href=\"https:\/\/www.youtube.com\/watch?v=-5iCSkOsHik\">Firefox Monument<\/a>.<\/p>\n<p>How do you get to it all, you might ask? Just click on Firefox in the Firefox Menu and choose About Firefox.
