The Firefox 139 branch has entered the beta testing stage, with a release scheduled for May 27.     <\/p>\n<p>Key innovations in Firefox 138:  <\/p>\n<ul>\n<li class=\"l\"> A new profile management system has been proposed. In the profile form, users can create fully independent browsing sessions, each with its own settings, history, bookmarks, extensions, and internal databases. Each profile is stored in a separate subdirectory \u2018~\/.mozilla\/firefox\/\u2019. You can assign a color scheme, icon, and name to each profile. Switching between profiles and creating new ones is done through a new section displayed at the top of the main menu.     <center><img decoding=\"async\" alt=\"Release of Firefox 138\" src=\"\/wp-content\/uploads\/2025\/04\/971dc008bd757d9f63c4d6917313ca87.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<p>The new profile management interface is not yet enabled by default for everyone and will gradually be activated for an increasing percentage of users. To force-enable it, you can activate the \u2018browser.profiles.enabled\u2019 parameter on the about:config page. The session separation technology is similar to old profiles, which were activated from the command line using the \u2018-P\u2019 option, but the interfaces and profile lists of the old and new systems do not overlap (new profiles are not shown in the old interface launched with the \u2018firefox --ProfileManager\u2019 command, and old profiles are not shown in the new interface available through the menu).     <\/p>\n<p>Old interface:  <center><img decoding=\"async\" alt=\"Release of Firefox 138\" src=\"\/wp-content\/uploads\/2025\/04\/ccc446a6224ebb52870c72f577c01947.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>    <\/p>\n<p>New interface:  <center><img decoding=\"async\" alt=\"Release of Firefox 138\" src=\"\/wp-content\/uploads\/2025\/04\/f5eff4b21ff9f98a53c333b2252802f6.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>    <\/p>\n<li class=\"l\"> Contextual recommendations with weather forecasts are displayed in the address bar when typing words related to weather or city names. This feature is currently available by default only for users in the United States. It can be enabled through the \u2018browser.urlbar.suggest.weather\u2019 setting on the about:config page.      <center><img decoding=\"async\" alt=\"Release of Firefox 138\" src=\"\/wp-content\/uploads\/2025\/04\/3a589daacd70422fb6ebabc9735e7221.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> A new option has been added to the context menu, displayed when right-clicking on tab buttons, allowing users to copy the link to the page shown in the tab.\n<li class=\"l\"> On launch in Windows 11, pop-ups and menus now display in a style that matches the aesthetics of the operating system.\n<li class=\"l\"> Improved autofill for address and credit card number fields. Autofill now correctly applies to forms that are dynamically updated as information is filled in (autofill will work in fields that appear only after entering other fields, for example, when an address field appears after filling in the city field).\n<li class=\"l\"> The configurator has introduced the ability to override contrast colors. Instead of the colors used on websites for background and foreground, you can now set your own colors or use system contrast settings for web content.      <center><img decoding=\"async\" alt=\"Release of Firefox 138\" src=\"\/wp-content\/uploads\/2025\/04\/5dd136405410bf25d874de4d7a4cd9aa.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Support for integrity checks of imported JavaScript modules via hash has been added, using the new \u2018integrity\u2019 field in the metadata for .\n<li class=\"l\"> The Error.isError method has been added, allowing you to check if a given value is an instance of the Error object.\n<li class=\"l\"> To enhance compatibility with other browsers, support for the Error.captureStackTrace function has been added.\n<li class=\"l\"> The size and style of the font in <h1> elements have been unified, which are now independent of the use of <h1> within <article>, <aside>, <nav>, and <section> blocks.\n<li class=\"l\"> The \u2018import\u2019 statement has been updated to allow the specification of attributes that can set additional metadata when importing modules. Using the \u2018type: 'json'\u2019 attribute, JSON modules can now be imported. import data from \u2018https:\/\/example.com\/data.json\u2019 with { type: 'json' };\n<li class=\"l\"> A new property degradationPreference has been proposed for WebRTC applications, allowing you to prioritize frame rate or resolution in cases where reduced network bandwidth does not allow for all specified parameters to be met.\n<li class=\"l\"> In the returned <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=\"3100\">proxy server<\/a> The HTTP header \"Clear-Site-Data\" has added support for the \"cache\" directive, which allows the server to inform the client about the need to clear data related to the processed URL from the browser cache. For example, clearing can be initiated when a user ends their session on the site to reduce privacy risks.\n<li class=\"l\"> In the web developer tools under the Network panel, a new column \"Path\" has been implemented, which shows the full path of the requested resource.    <center><img decoding=\"async\" alt=\"Release of Firefox 138\" src=\"\/wp-content\/uploads\/2025\/04\/64b91894370bd0b589119c470df8ea6b.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> In the version for the Android platform:\n<ul>\n<li class=\"l\"> On tablets, desktop mode is enabled by default, which can be disabled in the settings.\n<li class=\"l\"> Bookmark sorting support and the ability to pin folders to the top of the bookmarks list have been added.\n<li class=\"l\"> Support has been implemented <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/ssl-sertifikat\/\"   title=\"for TLS certificates\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"975\">for TLS certificates<\/a> for client authentication on the server.\n<li class=\"l\"> The Share button can now be used to send uploaded files or links to other users.\n<li class=\"l\"> Support for sorting uploaded files by time and categories has been added.  <\/ul>\n<\/ul>\n<p>In addition to new features and bug fixes, Firefox 138 has addressed 14 vulnerabilities. Six vulnerabilities are caused by memory management issues, such as buffer overflows and accessing already released memory areas. These issues could potentially lead to the execution of malicious code when opening specially crafted pages. Notably, there is also a vulnerability in the \"copy as cURL\" feature in the web developer tools, allowing for the injection of custom commands due to inadequate escaping of special characters.<br \/>\n<br \/>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63159\">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 138 \u0438 \u0441\u0444\u043e\u0440\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u044b \u043e\u0431\u043d\u043e\u0432\u043b\u0435\u043d\u0438\u044f \u043f\u0440\u043e\u0448\u043b\u044b\u0445 \u0432\u0435\u0442\u043e\u043a \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; 115.23.0 \u0438 128.10.0. \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 139, \u0440\u0435\u043b\u0438\u0437 \u043a\u043e\u0442\u043e\u0440\u043e\u0439 \u043d\u0430\u043c\u0435\u0447\u0435\u043d \u043d\u0430 27 \u043c\u0430\u044f. \u041e\u0441\u043d\u043e\u0432\u043d\u044b\u0435 \u043d\u043e\u0432\u0448\u0435\u0441\u0442\u0432\u0430 \u0432 Firefox 138: \u041f\u0440\u0435\u0434\u043b\u043e\u0436\u0435\u043d\u0430 \u043d\u043e\u0432\u0430\u044f \u0441\u0438\u0441\u0442\u0435\u043c\u0430 \u0443\u043f\u0440\u0430\u0432\u043b\u0435\u043d\u0438\u044f \u043f\u0440\u043e\u0444\u0438\u043b\u044f\u043c\u0438. \u0412 \u0444\u043e\u0440\u043c\u0435 \u043f\u0440\u043e\u0444\u0438\u043b\u0435\u0439 \u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u044c \u043c\u043e\u0436\u0435\u0442 \u0441\u043e\u0437\u0434\u0430\u0432\u0430\u0442\u044c \u043f\u043e\u043b\u043d\u043e\u0441\u0442\u044c\u044e \u043d\u0435\u0437\u0430\u0432\u0438\u0441\u0438\u043c\u044b\u0435 \u0441\u0435\u0430\u043d\u0441\u044b \u0440\u0430\u0431\u043e\u0442\u044b \u0441 \u0431\u0440\u0430\u0443\u0437\u0435\u0440\u043e\u043c, \u0441\u043e \u0441\u0432\u043e\u0438\u043c\u0438 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":123865,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-123864","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.1.1 -
