Since then we have launched new products to complement your experience when you\u2019re using Firefox and serve you beyond the browser. This includes <a href=\"https:\/\/www.mozilla.org\/en-US\/firefox\/facebookcontainer\/\">Facebook Container<\/a>, <a href=\"https:\/\/monitor.firefox.com\/\">Firefox Monitor<\/a> and <a href=\"https:\/\/send.firefox.com\/\">Firefox Send<\/a>. Collectively, they work to protect your privacy and keep you safe so you can do the things you love online with ease and peace of mind. We\u2019ve been delivering on that promise to you for more than twenty years by putting your security and privacy first in the building of products that are open and accessible to all.<\/p>\n<p>Today\u2019s new Firefox release continues to bring fast and private together right at the crossroads of performance and security. It includes improvements that continue to keep Firefox fast while giving you more control and assurance through new features that your personal information is safe while you&#8217;re online with us.<\/p>\n<p style=\"text-align: center;\"><a class=\"button button-product\" href=\"https:\/\/www.mozilla.org\/firefox\/new\/?utm_source=blog.mozilla.org&amp;utm_campaign=button;utm_medium=referral\">Download Firefox<\/a><\/p>\n<p>To see how much faster Firefox is today take a look:<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/NzqJ09_cn28\" width=\"835\" height=\"505\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><span style=\"display: inline-block; width: 0px; overflow: hidden; line-height: 0;\" data-mce-type=\"bookmark\" class=\"mce_SELRES_start\">\ufeff<\/span><\/iframe><\/p>\n<h3>How did we make Firefox faster?<\/h3>\n<p>To make Firefox faster, we simply prioritized our performance management \u201cto-do\u201d list. We applied many of the same principles of time management just like you might prioritize your own urgent needs. For example, before you go on a road trip, you check for a full tank of gas, make sure you have enough oil, or have the right air pressure in your tires.<\/p>\n<p>For this latest Firefox release, we adopted the well-known time management strategy of \u201c<a href=\"https:\/\/www.youtube.com\/watch?v=y2X7c9TUQJ8\">procrastinate on purpose<\/a>.\u201d The result is that Firefox is better at performing tasks at the optimal time. Here\u2019s how we reorganized our to-do list to make Firefox faster:<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><b><i>Deprioritize least commonly used features<\/i><\/b>: We reviewed areas that we felt could be delayed and delivered on \u201cpainting\u201d the page faster so you can browse quicker. This includes delaying set Timeout in order to prioritize scripts for things you need first while delaying others to help make the main scripts for Instagram, Amazon and Google searches execute 40-80% faster; scanning for alternative style sheets after page load; and not loading the auto-fill module unless there is an actual form to complete.<\/li>\n<li><b><i>Suspend Idle Tabs<\/i><\/b>: You shouldn\u2019t feel guilty about opening a zillion tabs, but keeping all those tabs open uses your computer\u2019s memory and slows down its performance. Firefox will now detect if your computer\u2019s memory is running low, which we define as lower than 400MB, and suspend unused tabs that you haven\u2019t used or looked at in a while. Rest assured if you decide you want to review that webpage, simply click on the tab, and it will reload where you left off.<\/li>\n<li><b><i>Faster startup after customization: <\/i><\/b>For users who have customized their browser with an add-on like a favorite theme, for example changing it to the seasons of the year, or utilizing one of the popular ad-blockers, we\u2019ve made it so that the browser skips a bunch of unnecessary work during subsequent start-ups.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3>New Privacy Protections<\/h3>\n<p>Privacy has always been core to Mozilla\u2019s mission, and the recent news and events have given people more reason to care about their privacy while online. In 2018, we launched privacy-focused features like <a href=\"https:\/\/blog.mozilla.org\/blog\/2018\/01\/23\/latest-firefox-quantum-release-now-available-with-new-features\/\">opt-in Tracking Protection on the desktop<\/a>, <a href=\"https:\/\/blog.mozilla.org\/blog\/2018\/04\/12\/latest-firefox-for-ios-now-available-with-tracking-protection-by-default\/\">Tracking protection by default on iOS,<\/a> and our <a href=\"https:\/\/blog.mozilla.org\/firefox\/facebook-container-extension\/\">popular Facebook Container Extension<\/a>.<\/p>\n<p>For today\u2019s release we continue to bring you privacy features and set protections to help you feel safe online when you are with Firefox. Today\u2019s privacy features include:<\/p>\n<ul>\n<li><b><i>Blocking fingerprinting and cryptomining:<\/i><\/b> In August 2018, we shared our adapted <a href=\"https:\/\/blog.mozilla.org\/futurereleases\/2018\/08\/30\/changing-our-approach-to-anti-tracking\/\">approach to anti-tracking<\/a> to address growing consumer demand for features and services that respect online privacy. One of the three key areas we said we\u2019d tackle was mitigating harmful practices like <a href=\"https:\/\/blog.mozilla.org\/firefox\/how-to-block-fingerprinting-with-firefox\">fingerprinting<\/a> which builds a digital fingerprint that tracks you across the web, and <a href=\"https:\/\/blog.mozilla.org\/firefox\/block-cryptominers-with-firefox\/\">cryptomining<\/a> which uses the power of your computer\u2019s CPU to generate <a href=\"https:\/\/blog.mozilla.org\/firefox\/what-is-cryptocurrency\/\">cryptocurrency<\/a> for someone else\u2019s benefit. Based on recent testing of this <a href=\"https:\/\/blog.mozilla.org\/futurereleases\/2019\/04\/09\/protections-against-fingerprinting-and-cryptocurrency-mining-available-in-firefox-nightly-and-beta\/\">feature in our pre-release channels last month<\/a>, today\u2019s Firefox release gives you the option to \u201cflip a switch\u201d in the browser and protect yourself from these nefarious practices.\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>To turn this feature on click on the small \u201ci\u201d icon in the address bar and under Content Blocking, click on the Custom gear on the right side. The other option is to go to your Preferences. Click on Privacy &amp; Security on the left hand side. From there, users will see Content Blocking listed at the top. Select Custom and check \u201cCryptominers\u201d and \u201cFingerprinters\u201d so that they are both blocked.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<div id=\"attachment_12160\" style=\"width: 1871px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-12160\" decoding=\"async\" loading=\"lazy\" class=\"wp-image-12160 size-full\" src=\"https:\/\/blog.mozilla.org\/wp-content\/uploads\/2019\/05\/Fx67_Content_Blocking_Options_EN.png\" alt=\"\" width=\"1861\" height=\"1838\" srcset=\"https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Content_Blocking_Options_EN.png 1861w, https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Content_Blocking_Options_EN-300x296.png 300w, https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Content_Blocking_Options_EN-768x759.png 768w, https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Content_Blocking_Options_EN-600x593.png 600w, https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Content_Blocking_Options_EN-1000x988.png 1000w\" sizes=\"(max-width: 1861px) 100vw, 1861px\" \/><p id=\"caption-attachment-12160\" class=\"wp-caption-text\">Block cryptominers and fingerprinters<\/p><\/div>\n<ul>\n<li><b><i>Personalize your Private Browsing Experience<\/i><\/b>: Of the <a href=\"https:\/\/blog.mozilla.org\/firefox\/the-different-types-of-privacy-protection\/\">many types of privacy protections that Firefox offers<\/a>, Private Browsing continues to be one of our most popular features. Private Browsing deletes cookies when you close the browser window and doesn\u2019t track history. Plus, Private Browsing also blocks tracking cookies by default. Based on user feedback, <a href=\"https:\/\/blog.mozilla.org\/firefox\/save-passwords-in-private-browsing-firefox\">we\u2019re giving more controls for you to get the most out of their Private Browsing experience<\/a>.\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong><i>Saving Passwords<\/i> <\/strong>&#8211; \u00a0Although you may enjoy what Private Browsing has to offer, you may still want some of the convenience from a typical Firefox experience. This included not having to type in passwords each time you visit a site. In today\u2019s release, you can visit a site in Private Browsing without the hassle of typing in your password each time. Registering and saving passwords for a website in Private Browsing will work just as it does in normal mode.<\/li>\n<li><strong><i>Enable or Disable add-ons\/web extensions<\/i><\/strong> &#8211; Starting with today\u2019s release, you can now decide which extensions you want to enable or disable in Private Browsing. As part of installing an extension, Firefox will ask if it should be allowed to run in Private Browsing, with a default of Don\u2019t Allow. For extensions you\u2019ve installed before today\u2019s release, you can go to your Add-Ons menu and enable or disable for Private Browsing by simply clicking on the extension you\u2019d like to manage.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<div id=\"attachment_12161\" style=\"width: 1340px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-12161\" decoding=\"async\" loading=\"lazy\" class=\"wp-image-12161 size-full\" src=\"https:\/\/blog.mozilla.org\/wp-content\/uploads\/2019\/05\/Fx67_Private_Browsing_EN.png\" alt=\"\" width=\"1330\" height=\"142\" srcset=\"https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Private_Browsing_EN.png 1330w, https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Private_Browsing_EN-300x32.png 300w, https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Private_Browsing_EN-768x82.png 768w, https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Private_Browsing_EN-600x64.png 600w, https:\/\/blog.mozilla.org\/blogarchive\/files\/2019\/05\/Fx67_Private_Browsing_EN-1000x107.png 1000w\" sizes=\"(max-width: 1330px) 100vw, 1330px\" \/><p id=\"caption-attachment-12161\" class=\"wp-caption-text\">Manage existing add-ons<\/p><\/div>\n<h3>Additional features in today\u2019s release:<\/h3>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><b><i>Online accessibility for all &#8211;<\/i><\/b><i> <\/i>Mozilla has always strived to make the web easier to access for everyone.
