This release marks the last of the monthly stable updates, as Mozilla transitions to a biweekly release schedule for the browser.<\/p>\n<h3>Key Features<\/h3>\n<h4>Built-in Containers<\/h4>\n<p>The standout feature of Firefox 153 is the integrated container tabs, which allow users to separate cookies by container. This functionality is designed to facilitate the use of multiple accounts on the same site without cross-contamination. Users can easily manage accounts\u2014like personal and work social media\u2014within a single browser window. Mozilla has provided container options for years through add-ons, but with this update, four preconfigured containers\u2014Personal, Banking, Shopping, and Work\u2014are available by default. Users can also create additional containers if needed.<\/p>\n<p>To utilize containers, right-click on the new tab button to select one, or right-click an existing tab to open it in a container tab. The tabs are color-coded and have an associated icon in the URL bar for easy identification.<\/p>\n<h4>QR Codes and PDF Enhancements<\/h4>\n<p>Firefox 153 also allows users to create QR codes for open tabs. Simply right-click a tab and select the option to generate a QR code. This feature is particularly useful for sharing links offline.<\/p>\n<p>In addition to QR code support, the PDF editing capabilities in Firefox have been improved. Users can now merge PDFs by dragging them into the sidebar, as well as add images as new pages, which is practical for incorporating covers or diagrams into documents.<\/p>\n<h4>Additional Improvements<\/h4>\n<p>Other notable changes include:<\/p>\n<ul>\n<li>More quick actions in the address bar, such as launching the Firefox Labs or using a color picker.<\/li>\n<li>A visual indication in the address bar when a website has permission to access your location.<\/li>\n<li>Improved support for HDR video playback on Windows, although some limitations exist for specific laptop displays.<\/li>\n<li>On macOS, Firefox now supports a system-wide full-screen keyboard shortcut.<\/li>\n<\/ul>\n<p>Users can also explore an AI mode and its associated features if they are part of testing Smart Window.<\/p>\n<h3>How to Get Firefox 153<\/h3>\n<p>Firefox 153 is available for download from the Mozilla FTP, and it will be rolled out to existing users starting July 21. For users on Ubuntu, updates will occur automatically via the Snap Store, unless another package format is in use.<\/p>\n<p>For more details, visit the Mozilla support page for using container tabs, and stay updated on the latest Firefox developments on their official channels.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mozilla has launched Firefox 153, introducing a variety of new features including built-in container tabs, QR code generation, and enhanced quick actions in the&hellip;<\/p>\n","protected":false},"author":0,"featured_media":3966,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1036,58,248,4],"tags":[],"class_list":["post-3965","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-containers","category-firefox","category-mozilla","category-news"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Discover the New Features of Firefox 153: Built-In Container Tabs, Rounded Corners, and More!
