The release of the web browser has taken place , as well as Firefox 68.5 for the Android platform. Additionally, an update has been formed with long-term support . Soon moving to the stage of will transition to Firefox 74, which is scheduled for release on March 10 (project to a 4-week ).
:
- Support for the DNS over HTTPS (DoH) service has been added , in addition to the previously offered CloudFlare DNS server ("https://1.1.1.1/dns-query"). Activate DoH and select the network connection settings.
- The first phase has been implemented of support for extensions installed via alternative methods. This change only affects the installation of extensions in common directories (/usr/lib/mozilla/extensions/, /usr/share/mozilla/extensions/ or ~/.mozilla/extensions/), processed by all instances of Firefox on the system (regardless of user). This method is typically used for pre-installing extensions in distributions, for unsolicited insertion alongside third-party applications, for integrating malicious extensions, or for delivering an extension with its installer. In Firefox 73, such extensions will continue to work but will be moved from the common directory to individual user profiles, i.e., they will be converted to the format used when installed via the extensions manager.
- A global scaling base level has been implemented, applicable to all pages, rather than tied to specific sites. You can change the overall scale in settings (about:preferences) under the 'Language and Appearance' section. The settings also now include an option that allows scaling to be applied only to text, without affecting images.
- The dialog prompting to save logins now appears only if the login value in the input field has been changed.
- At with NVIDIA drivers newer than release 432 and a screen resolution less than 1920×1200 includes the WebRender compositing system [[https://wiki.mozilla.org/Platform/GFX/WebRender_Where]]. The WebRender compositing system is written in Rust and offloads rendering operations from the page content to the GPU.
- using the 'Site Specific Browser' (SSB) concept for
interacting with a web application like a regular desktop program. In mode
SSB hides menus, the address bar, and other browser interface elements, allowing only links to the current site's pages to be opened in the current window (external links open in a separate browser window). Unlike the existing kiosk mode, this operates not in full-screen mode but in a regular window, without the interface elements specific to Firefox. To open a link in SSB mode, a command-line flag "—ssb" is proposed, which can be used when creating shortcuts for web applications. This mode can also be invoked with the "Launch Site Specific Browser" button found in the page action menu (the three dots to the right of the address bar). By default, this mode is inactive and needs to be enabled by setting "browser.ssb.enabled = true" in about:config. - In high-contrast mode, designed for people with visual impairments or color perception issues, support for background images has been added. To maintain readability and ensure an adequate level of contrast, visible text is separated from the background with a distinct background color that uses the active theme's color.
- Sound quality has been improved when speeding up or slowing down playback;
- Enhanced auto-detection of outdated text encodings on pages where encoding information is not explicitly provided.
- The search bar in the web console now allows filtering by missing keys by indicating the symbol "-" before the mask or regular expression. For example, the search query "-img" will output all elements that do not have the string "img," while "-/(cool|rad)/" will show elements that do not match the regular expression "/(cool|rad)/."
- New CSS properties have been added. and to control scrolling behavior when reaching the logical boundary of the scrolling area.
- SVG has added support for properties and .
- The HTMLFormElement has added the method , which initiates programmatic form data submission similar to clicking a submit button. This function can be used when developing custom submit buttons, for which calling form.submit() is insufficient since it does not trigger interactive validation of parameters, generate a 'submit' event, or transmit data bound to the submit button.
- Properties and The Window objects now always return the actual specified width and height of the area (), not the size of the visible part (Visual Viewport).
- Performance optimization for web development tools. Reduced load when collecting statistics for the network activity monitoring panel. In the JavaScript debugger and web console, the loading of large scripts has been accelerated with bindings to their original source texts (source-mapped).
- In the web console, issues with exceeding the current domain area (, Cross-Origin Resource Sharing) are now displayed as errors instead of warnings. Variables defined in expressions have become available for auto-completion in the console.
- In the web development tools, under the network inspection section, decoding of messages (JSON, MsgPack, and CBOR) in the WAMP (WebSocket Web Application Messaging Protocol) format transmitted over WebSocket connections has been implemented.
In addition to new features and bug fixes, Firefox 73 has addressed , of which 11 (collected under CVE-2020-6800 and CVE-2020-6801) are marked as potentially capable of executing malicious code when opening specially crafted pages. It should be recalled that memory issues, such as buffer overflows and access to already freed memory areas, have recently been labeled as dangerous but not critical.
