And as we prepare to release the newest version of our Firefox browser, now affectionately known as the \u201cnew Firefox,\u201d we thought it would be fun to give a rundown of some of the colossal numbers that went into this global undertaking by all of our engineers, volunteers, partners and staff.<\/p>\n<p>Of course the answer to the universe is 42. But our gratitude comes down to two words: thank you!<\/p>\n<p>We couldn\u2019t do any of this without our loyal and rabid users who make us try harder, work later, code longer, cheer louder, and fight for more and more of what\u2019s right in keeping the internet open, safe, and exciting.<\/p>\n<p>Thank you, dear users, from all the bits and bytes and numbers and most importantly, for the one thing that can\u2019t be measured and can\u2019t be done without: the heart.<\/p>\n<h3><b>The New Firefox Quantum By the Numbers<\/b><\/h3>\n<p>How <b>long<\/b> did it take to make?<\/p>\n<ul>\n<li>A full year. The project kicked off in 2016 and here we are.<\/li>\n<\/ul>\n<p>How many<b> lines of code<\/b> were touched?<\/p>\n<ul>\n<li>75,342 files changed<\/li>\n<li>4,888,199 lines were added<\/li>\n<li>6,886,199 lines were changed<\/li>\n<\/ul>\n<p>How <b>many web extensions<\/b> and compatible add-ons are available?<\/p>\n<ul>\n<li>6,000 listed <a href=\"https:\/\/blog.mozilla.org\/firefox\/new-firefox-add-ons\/\">web extensions<\/a> on AMO<\/li>\n<li>Over 70% of add-on users already have at least one installed<\/li>\n<\/ul>\n<p>How many <b>responsiveness and performance bugs<\/b> were fixed?<\/p>\n<ul>\n<li>We triaged 369 bugs targeted specifically at performance and responsiveness.<\/li>\n<\/ul>\n<p>How many bugs were filed and fixed for the <b>user experience<\/b>?<\/p>\n<ul>\n<li>For the user experience, we filed and fixed 1,190 software bugs.<\/li>\n<\/ul>\n<p>How many <b>authors contributed code<\/b>?<\/p>\n<ul>\n<li>More than 700 authors contributed code to Firefox since the August 6th release.<\/li>\n<\/ul>\n<p>How many <b>volunteers<\/b> contributed to code development?<\/p>\n<ul>\n<li>80 contributors from all over the world, with nearly every time-zone represented in round-the-clock awesomeness!<\/li>\n<\/ul>\n<p>How many ways can you <b>customize the toolbar<\/b> in the new Firefox?<\/p>\n<ul>\n<li>There are <b>265,252,859,191,742,656,903,069,040,640,000*<\/b> more ways to customize the new Firefox toolbar right out of the box!<\/li>\n<\/ul>\n<p>How many more<b> toolbar animations <\/b>are there?<\/p>\n<ul>\n<li>There were 2 animations in the previous version of Firefox (downloading and bookmarking). In the new Firefox we have 7 animations (stop-reload, Pocket expansion, bookmarking burst, Pocket library drop, bookmarking library drop, downloading, pin to overflow). That&#8217;s an increase of <b>250%<\/b>.<\/li>\n<\/ul>\n<h3><b>Who Says Fast Can\u2019t Also Be Good?<\/b><\/h3>\n<p>According to real-world performance testing by our army of Mozillians, here\u2019s one more really, really interesting number: the new Firefox is running about 2x faster than our previous build. \u00a0Not final. Not fully vetted. But definitely faster.<\/p>\n<p>We hope you\u2019ll feel the excitement and enjoy the new Firefox, too. So until next release, let\u2019s keep these numbers growing and all keep browsing for good!<\/p>\n<p>\u00a0<\/p>\n<p>*Math for all you math whizzes! In Firefox 56 there are 6.204484e+23 (24 factorial) possible configurations of toolbar items (23 factorial if you exclude the non-removable back-forward-location-bar item). In Firefox 57 there are 2.6525286e+32 (30 factorial) possible configurations of toolbar items (28 factorial if you exclude the non-removable back-forward and location bar, including the number of Spacers set at 2 since that&#8217;s the default though their usage is not limited)) That means that in Firefox 57 there are 265,252,859,191,742,656,903,069,040,640,000 more ways to customize Firefox (30! &#8211; 24!).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>There are 206 bones in the human body.
