The Firefox 151 branch will enter beta testing in the coming hours, with its release scheduled for May 19.     <\/p>\n<p>Key innovations in Firefox 150 (1, 2, 3):  <\/p>\n<ul>\n<li class=\"l\"> A total of 359 vulnerabilities have been fixed (56 vulnerabilities are aggregated under CVE-2026-6784, 155 under CVE-2026-6785, 110 under CVE-2026-6786, and the remaining under separate CVEs). 345 vulnerabilities were caused by memory handling issues such as buffer overflows and accessing already freed memory areas. These problems could potentially allow for the execution of malicious code when specially crafted pages are opened. Most issues were identified through code review by AI models.\n<li class=\"l\"> A button has been added to the context menu shown when right-clicking a link, allowing for quick opening of the link's content in Split View mode, which lets you view the content of two tabs side by side in one window. After activating Split View from the context menu, it is now possible to select a second tab by searching through open tabs. The context menu for tabs also features a 'Reverse Tabs' button that allows for swapping tabs between the left and right panels in Split View.    <img decoding=\"async\" alt=\"The LibreSSL project has announced the release of version 4.3.0, which is now available on OpenBSD mirrors. This is a development release for the 4.3.x branch, so the developers encourage the community to actively test it.\" src=\"\/wp-content\/uploads\/2026\/04\/9518013037952d68883c74b26d068347.png\" style=\"display:block;margin: 0 auto\" \/>\n<li class=\"l\"> A new service page, about:translations, has been proposed, providing a separate interface for translating text from one language to another. Translation occurs in real-time as the text is typed. A quick way to access this page is through a suggestion that appears when you start typing the word 'translate' in the address bar.    <img decoding=\"async\" alt=\"The LibreSSL project has announced the release of version 4.3.0, which is now available on OpenBSD mirrors.

This interface can be invoked by double-pressing Ctrl+'.' in text input fields.      <img decoding=\"async\" alt=\"The LibreSSL project has announced the release of version 4.3.0, which is now available on OpenBSD mirrors.

To access internal resources, users must grant the web application special permissions, as such activity is exploited by attackers to carry out CSRF attacks on routers, access points, printers, corporate web interfaces, and other devices and services that accept requests only from the local network. Additionally, scanning internal resources can be used for indirect identification or information gathering about the local network. Previously, such protection only applied when enhanced tracking protection (ETP, Enhanced Tracking Protection =&gt; Strict) was enabled.\n<li class=\"l\"> New profile management system implemented in Windows builds, allowing users to save profiles to a file and supporting the use of Firefox for isolated web applications.\n<li class=\"l\"> A new option has been added to settings (Settings &gt; Tabs &gt; Drag tabs) to disable the creation of tab groups when dragging one tab over another for those who prefer to manage grouping only through the context menu.\n<li class=\"l\"> Integrated free <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/vpn\/\" title=\"VPN\" data-wpil-keyword-link=\"linked\">VPN<\/a>-service Firefox VPN is now available to users in Canada, in addition to users from the US, France, Germany, and the UK. The service allows accessing websites not directly, but through intermediate proxies-<a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/\" title=\"servers\" data-wpil-keyword-link=\"linked\">servers<\/a> in different countries, hiding the user's IP address. There is an option to enable VPN only for selected sites. To activate the VPN, users must register an account with Mozilla. The VPN service has a limit of 50 gigabytes of traffic per month.\n<li class=\"l\"> In the web development tools, a separate section has been added to the CSS panel with pseudo-classes specific to elements, such as the pseudo-class &quot;:open&quot; used for expandable elements like &lt;dialog&gt;, and &quot;:visited&quot; &mdash; used for elements &lt;a&gt; and &lt;area&gt;.   <img decoding=\"async\" alt=\"The LibreSSL project has announced the release of version 4.3.0, which is now available on OpenBSD mirrors.

The function can specify two images that will be selected based on light or dark mode: light-dark(url('light-icon.png'), url('dark-icon.png'));\n<li class=\"l\"> The color-mix() CSS function now supports mixing an arbitrary number of color values (previously only allowed mixing two colors). color-mix(in oklab, teal 20%, olive 30%, blue 50%)\n<li class=\"l\"> For images that are loaded while scrolling the page (&#171;loading=lazy&#187;), options defined through the &#171;srcset&#187; property now support the &#171;sizes=auto&#187; attribute. This value allows the browser to automatically select the appropriate image from the &#171;srcset&#187; based on the width available for the &#171;img&#187; element.\n<li class=\"l\"> Work has been done in the Firefox version for Android to improve stability, smoothness, and responsiveness during navigation.    <\/ul>\n<p>Source: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65260\">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 150 \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; 140.10.0 \u0438 115.35.0. \u041d\u0430 \u0441\u0442\u0430\u0434\u0438\u044e \u0431\u0435\u0442\u0430-\u0442\u0435\u0441\u0442\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f \u0432 \u0431\u043b\u0438\u0436\u0430\u0439\u0448\u0438\u0435 \u0447\u0430\u0441\u044b \u0431\u0443\u0434\u0435\u0442 \u043f\u0435\u0440\u0435\u0432\u0435\u0434\u0435\u043d\u0430 \u0432\u0435\u0442\u043a\u0430 Firefox 151, \u0440\u0435\u043b\u0438\u0437 \u043a\u043e\u0442\u043e\u0440\u043e\u0439 \u043d\u0430\u043c\u0435\u0447\u0435\u043d \u043d\u0430 19 \u043c\u0430\u044f. \u041e\u0441\u043d\u043e\u0432\u043d\u044b\u0435 \u043d\u043e\u0432\u0448\u0435\u0441\u0442\u0432\u0430 \u0432 Firefox 150 (1, 2, 3): \u0423\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u043e 359 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0435\u0439 (56 \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0435\u0439 \u0441\u043e\u0431\u0440\u0430\u043d\u043e \u043f\u043e\u0434 CVE-2026-6784, 155 \u043f\u043e\u0434 CVE-2026-6785, 110 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":8,"featured_media":169690,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-169689","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 -
