Firefox 140 is classified as part of the long-term support (ESR) branches, with updates released throughout the year. Additionally, updates for previous long-term support branches 115.25.0 and 128.12.0 have been formed. The Firefox 141 branch has entered beta testing, with its release scheduled for July 22.     <\/p>\n<p>Key Innovations in Firefox 140:  <\/p>\n<ul>\n<li class=\"l\"> The vertical tabs panel now allows resizing of the pinned tabs area, used for quick access to important pages. To increase the number of pinned tabs (by reducing the space for regular open tabs), simply move the section divider with the mouse.    <center><img decoding=\"async\" alt=\"Firefox 140 Release\" src=\"\/wp-content\/uploads\/2025\/06\/bf359cb7d4a23d571404e496d7a7787f.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>  <center><img decoding=\"async\" alt=\"Firefox 140 Release\" src=\"\/wp-content\/uploads\/2025\/06\/d21d67c6ef999d91e48c5c22ca2b52c9.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> The context menu displayed when right-clicking on a tab or a group of selected tabs has been enhanced with the 'Unload Tab' option, allowing users to unload tabs from memory to reduce memory and CPU resource consumption.     <center><img decoding=\"async\" alt=\"Firefox 140 Release\" src=\"\/wp-content\/uploads\/2025\/06\/2412c14d0bc47875ad5bb26739b8f8a1.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> The ability to add custom search engines has been provided. To add search engines on sites that use the  tag to describe search engine parameters, the 'Add Search Engine' option can be used in the context menu displayed when right-clicking on the search field. A search engine can also be added in the configurator (Settings &gt; Search &gt; Add).    <center><img decoding=\"async\" alt=\"Firefox 140 Release\" src=\"\/wp-content\/uploads\/2025\/06\/c478ea23d5bfe8569be53318e06bc45b.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>  <center><img decoding=\"async\" alt=\"Firefox 140 Release\" src=\"\/wp-content\/uploads\/2025\/06\/7123fa66f040863913bace7bd8f78f98.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> The toolbar customization interface (Customize toolbar... in the context menu of the panel) now includes an option to remove the shortcut for the add-ons list. If the add-ons button is hidden, access to the add-ons management interface can be obtained through the 'Extensions' button in the main menu.    <center><img decoding=\"async\" alt=\"Firefox 140 Release\" src=\"\/wp-content\/uploads\/2025\/06\/4fe1836ea22a74dc2211e6eda7e7e10b.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> When translating the content of the entire page into another language, only the content of the visible part of the page is translated initially, with the remaining content translated as the user scrolls. This change reduces resource consumption and increases the interface responsiveness during translation.\n<li class=\"l\"> For users in Poland, Italy, and Austria, the address autofill feature in web forms has been enabled, which was previously available only for the USA, UK, Canada, Germany, and France.\n<li class=\"l\"> Components related to the Pocket service have been removed from the toolbar and new tab opening page, as Mozilla has discontinued its support.\n<li class=\"l\"> Access to device drivers via ioctl is restricted in the implementation of sandbox isolation for Linux.\n<li class=\"l\"> Support for the 'aria-keyshortcuts' attribute, defined in the ARIA (Accessible Rich Internet Applications) specification for people with disabilities, has been added. This attribute allows for specifying key combinations to switch focus to an element.\n<li class=\"l\"> The CookieStore API has been introduced, enabling the retrieval, setting, and deletion of cookies asynchronously from scripts executed in the context of HTML pages or Service Workers.\n<li class=\"l\"> The Custom Highlight API has been implemented, designed for arbitrary style changes to highlighted text areas, allowing for custom highlighting beyond the fixed styles provided by the browser for highlighted areas (::selection, ::inactive-selection) and syntax error highlighting (::spelling-error, ::grammar-error). For example, this new API allows web frameworks providing text editing tools to implement their own text highlighting mechanisms, different highlighting during simultaneous collaborative editing by multiple users, and error marking during spell checking. Previously, creating non-standard highlighting required complex manipulations of the DOM tree, but the Custom Highlight API offers ready-made operations for adding and removing highlights without affecting the DOM structure and applying styles tied to Range objects.\n<li class=\"l\"> Support for the pointerrawupdate event has been added, allowing for tracking pointer movement. Compared to the 'pointermove' event, the new event is generated more frequently and as data becomes available, which may be useful in applications that need to track pointer movement with high precision.\n<li class=\"l\"> In private browsing mode, sites are allowed to use Service Workers for background tasks and to utilize the IndexedDB API and DOM Cache with encrypted storage.\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\"> HTML attribute serialization now includes the escaping of the characters '' to complicate certain types of XSS attacks. Methods Element.innerHTML, Element.outerHTML, Element.getHTML, ShadowRoot.innerHTML, and ShadowRoot.getHTML will now replace the characters '' with &lt;&gt; when serializing HTML to a string.\n<li class=\"l\"> The web development tools in the inspection panel have enhanced search capabilities within the DOM tree of the current page. It is now possible to sort search results by the number of found elements and support for pseudo-classes.\n<li class=\"l\"> In the Android version, bookmark management has been simplified (a 'Select All' button has been added to perform operations on multiple bookmarks at once). The privacy browsing mode has enhanced security.          <\/ul>\n<p>In addition to new features and bug fixes, Firefox 140 has addressed 17 vulnerabilities. Six of these vulnerabilities are due to memory management issues, such as buffer overflows and access to already freed memory areas. These problems may potentially lead to the execution of malicious code when opening specially crafted pages. Notably, there is an issue with the built-in WebCompat extension in Firefox, which allows the identification of browser instances, including when viewing pages in private mode. This vulnerability is due to the ability to obtain a persistent identifier (UUID) through resource analysis provided by the WebCompat extension.      <\/p>\n<p>In the beta version of Firefox 141, memory consumption on the Linux platform has been reduced, and the requirement to restart after updating through the package manager has been removed.<br \/>\n<br \/>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63457\">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 140.
