The Firefox 122 branch has entered beta testing, with the release scheduled for January 23.         <\/p>\n<p>Key innovations in Firefox 121:  <\/p>\n<ul>\n<li class=\"l\"> On Linux, the use of composite Wayland is enabled by default instead of XWayland, which has resolved issues with touchpad functionality, gesture support on touch screens, and setting DPI for each monitor in Wayland-based environments. The use of Wayland also demonstrates improved graphics performance. However, due to the limitations of the Wayland protocol, there are issues with bringing the 'picture-in-picture' window to the foreground. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3749\">server<\/a> Wayland is replacing XWayland, which has resolved issues with touchpad operation, gesture support on touchscreen devices, and setting DPI for each monitor in Wayland-based environments. The use of Wayland also demonstrates improved graphics performance. However, due to limitations of the Wayland protocol, there are issues with bringing the 'picture-in-picture' window to the forefront.\n<li class=\"l\"> In the PDF viewer, a floating button has been implemented to delete drawings, text, and images added during PDF editing.    <center><img decoding=\"async\" alt=\"Firefox 121 Release\" src=\"\/wp-content\/uploads\/2023\/12\/099e357c3300d839aadc15c54fbb2511.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> On the Windows platform, a prompt for installing the AV1 Video Extension package has been implemented, enabling hardware acceleration for video decoding in the AV1 format.  <center><img decoding=\"async\" alt=\"Firefox 121 Release\" src=\"\/wp-content\/uploads\/2023\/12\/9fd749264ac48fd9377358500c355aa5.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> On the macOS platform, support for voice command control has been added.\n<li class=\"l\"> Support for lazy loading of iframe blocks has been added, allowing content outside the visible area not to load until the user scrolls to a location immediately preceding the element. To control the lazy loading of pages, the 'loading' attribute has been added to the 'iframe' tag, which can take the value 'lazy' (&lt;iframe loading=lazy&gt;). Lazy loading will help reduce memory consumption, lower traffic, and speed up the initial page opening.\n<li class=\"l\"> Support for lazy loading of iframe blocks has been added, allowing content outside the visible area not to be loaded until the user scrolls to the area immediately preceding the element. To manage lazy loading of pages in the iframe tag, the 'loading' attribute has been added, which can take the value 'lazy' (). Lazy loading will reduce memory consumption, lower traffic, and increase the speed of initial page loading.\n<li class=\"l\"> The CSS pseudo-class &laquo;:has()&raquo; has been added to check for the presence of a child element in the parent. For example, &laquo;p:has(span)&raquo; covers elements &lt;p&gt;, which contain an element &lt;span&gt;.\n<li class=\"l\"> The CSS property text-indent has been enhanced with the 'hanging' and 'each-line' parameters, simplifying the formatting of paragraph styles, such as bibliographies and poetry. It is now also permitted to combine multiple text-indent parameters in a single declaration, for example, 'text-indent: 3em hanging each-line'.\n<li class=\"l\"> The CSS property text-wrap has been updated with new parameters: 'balance' (which improves the uniform formatting of multiline text blocks, such as long headings) and 'stable' (which prevents reformatting of content during editing).\n<li class=\"l\"> The Date.parse() function now supports additional formats, such as MMM-DD-YYYY, specifying milliseconds, assigning the weekday before the date ('Wed, 1970-01-01'), and ignoring errors in the spelling of the weekday ('foo 1970-01-01').\n<li class=\"l\"> A static method Promise.withResolvers() has been added, allowing the use of resolve and reject callback functions for setting handlers that fulfill or reject Promise definitions after its creation.\n<li class=\"l\"> Support for return_call and return_call_indirect instructions has been added to WebAssembly for optimizing tail recursion, which helps reduce memory usage on the stack, improve performance, and enhance support for functional programming languages.\n<li class=\"l\"> In the WebTransport API, designed for sending and receiving data between the browser and <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-prohoster\/\"   title=\"proxy server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3019\">proxy server<\/a>, a sendOrder property has been added, allowing the setting of individual priorities for sending and receiving in bidirectional streams.\n<li class=\"l\"> Improvements in web development tools have focused on enhancing accessibility for individuals with disabilities, such as standardizing and increasing the focus indicator across various tools. The built-in JavaScript debugger has added an option 'Pause on debugger statement' to disable the debugger.    <center><img decoding=\"async\" alt=\"Firefox 121 Release\" src=\"\/wp-content\/uploads\/2023\/12\/a44b3cbc435faa6e2a49b79f5cb81048.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> In the Android version, crashes occurring during copying to the clipboard and displaying full-screen notifications have been resolved. Issues with rendering on Google Pixel 8 and Samsung Galaxy S22 smartphones have been addressed. An add-ons catalog has been introduced. In private browsing mode, third-party Cookies and access to local storage are blocked. In manual configuration mode, Enhanced Tracking Protection includes blocking code for tracking movements used in social media.                  <\/ul>\n<p>In addition to new features and bug fixes, Firefox 121 addresses 27 vulnerabilities. Among these, 13 vulnerabilities (11 grouped under CVE-2023-6864 and CVE-2023-6873) are marked as critical and stem from memory management issues, such as buffer overflows and the use of already freed memory areas. These issues could potentially allow an attacker to execute code by opening specially crafted web pages. Another critical vulnerability (CVE-2023-6135) is related to the NSS library's susceptibility to the 'Minerva' attack, which enables the recreation of a private key through data analysis via side channels.<br \/>\n<br \/>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=60310\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0421\u043e\u0441\u0442\u043e\u044f\u043b\u0441\u044f \u0440\u0435\u043b\u0438\u0437 web-\u0431\u0440\u0430\u0443\u0437\u0435\u0440\u0430 Firefox 121 \u0438 \u0441\u0444\u043e\u0440\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u043e \u043e\u0431\u043d\u043e\u0432\u043b\u0435\u043d\u0438\u0435 \u0432\u0435\u0442\u043a\u0438 \u0441 \u0434\u043b\u0438\u0442\u0435\u043b\u044c\u043d\u044b\u043c \u0441\u0440\u043e\u043a\u043e\u043c \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0438 &#8212; 115.6.0. \u041d\u0430 \u0441\u0442\u0430\u0434\u0438\u044e \u0431\u0435\u0442\u0430-\u0442\u0435\u0441\u0442\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f \u043f\u0435\u0440\u0435\u0432\u0435\u0434\u0435\u043d\u0430 \u0432\u0435\u0442\u043a\u0430 Firefox 122, \u0440\u0435\u043b\u0438\u0437 \u043a\u043e\u0442\u043e\u0440\u043e\u0439 \u043d\u0430\u043c\u0435\u0447\u0435\u043d \u043d\u0430 23 \u044f\u043d\u0432\u0430\u0440\u044f. \u041e\u0441\u043d\u043e\u0432\u043d\u044b\u0435 \u043d\u043e\u0432\u0448\u0435\u0441\u0442\u0432\u0430 \u0432 Firefox 121: \u0412 Linux \u043f\u043e \u0443\u043c\u043e\u043b\u0447\u0430\u043d\u0438\u044e \u0432\u043a\u043b\u044e\u0447\u0435\u043d\u043e \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u0435 \u043a\u043e\u043c\u043f\u043e\u0437\u0438\u0442\u043d\u043e\u0433\u043e \u0441\u0435\u0440\u0432\u0435\u0440\u0430 Wayland \u0432\u043c\u0435\u0441\u0442\u043e XWayland, \u0447\u0442\u043e \u043f\u043e\u0437\u0432\u043e\u043b\u0438\u043b\u043e \u0440\u0435\u0448\u0438\u0442\u044c \u043f\u0440\u043e\u0431\u043b\u0435\u043c\u044b \u0441 \u0440\u0430\u0431\u043e\u0442\u043e\u0439 \u0442\u0430\u0447\u043f\u0430\u0434\u0430, \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u043e\u0439 \u0436\u0435\u0441\u0442\u043e\u0432 \u043d\u0430 \u0441\u0435\u043d\u0441\u043e\u0440\u043d\u044b\u0445 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":112349,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-112348","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.2 -
