Firefox 75

Available Firefox 75.

• The Quantum Bar address bar, which debuted in Firefox 68, has received its first major update:
  • The size of the address bar significantly increases when it gains focus (browser.urlbar.update1).
  • Before the user starts typing, the dropdown menu displays top sites (browser.urlbar.openViewOnFocus).
  • In the dropdown menu with browsing history, the https:// protocol is no longer displayed,. Nowadays, using a secure connection is not surprising; it’s now important to draw users' attention not to the presence of HTTPS, but to its absence (browser.urlbar.update1.view.stripHttps).
  • Additionally, has been put into operation. the display of the www subdomain (the browser.urlbar.trimURLs setting returns both www and https:// simultaneously; there’s no point in adjusting the aforementioned setting).
  • The settings browser.urlbar.clickSelectsAll and browser.urlbar.doubleClickSelectsAll have been removed. Now the click behavior in the address bar on Linux matches that of macOS and Windows, which users have requested for 14 years..
• On systems using Wayland, hardware acceleration for WebGL has been added (widget.wayland-dmabuf-webgl.enabled). It doesn’t work with X11 as it would require a huge number of exceptions and hacks, (Mozilla does not have the immense resources of Google to test every existing version of drivers with every existing model of graphics cards). Wayland significantly simplifies the situation, allowing Martin Strynkowski from RedHat to write the necessary backend DMABuf. A pleasant bonus is that DMABuf can provide hardware acceleration for H.264 decoding (widget.wayland-dmabuf-vaapi.enabled). In the next release, hardware acceleration will also work with other video formats.
• Official packages in Flatpak format have been introduced, allowing session recovery on the KDE Plasma virtual desktop..
• on the same screen as the last used browser window. Deferred image loading support has been added. If an image has the attribute
• loading with the value lazy, the browser will load the image only when the user scrolls to the corresponding position on the page. Users from the UK (in addition to users from the US) will see sponsored content blocks (which can be disabled in settings) on the homepage.
• Support for TLS 1.0/1.1 has been re-enabled. Now is not the best time to hinder people's access to any resources, even slightly.
• Support for TLS 1.0/1.1 has been reinstated. Now is not the best time to even slightly hinder people's access to any resources.
• From now on, the background browser caches all trusted PKI certificates from certificate authorities known to Mozilla. This should improve compatibility with servers whose owners have incorrectly configured HTTPS.
• The about:policies page has been rewritten from XUL to HTML.
• The Web Crypto API now is available only for sites opened via a secure connection.
• Regarding HTML documents, Firefox now takes into account the X-Content-Type-Options:nosniff directive, which tells the browser not to heuristically determine the MIME type of content. Previously, 'nosniff' was only used for CSS and JS.
• In builds for macOS, the technology RLBox. C++ code of potentially vulnerable third-party libraries is converted into a WebAssembly module, the privileges of which are strictly limited, and then the module is compiled into machine code and executed in an isolated process. The first such library was Graphite. Additionally, macOS now allows reading certificates from the operating system's store (configuration setting security.osclientcerts.autoload), as well as fixed a bug that caused browser session restoration to put browser windows on the current desktop instead of the desktops where those windows were located in the previous session.
• In Windows, included direct composition (Direct Composition), which should positively affect performance. Additionally, fixed the inability to import logins from Chrome 80 and above.
• CSS:
  • Support for functions min(), max() and clamp().
  • window.name text-decoration-skip-ink gained the value all.
• JavaScript:
  • Support for public static fields in classes.
  • A class Intl.Locale.
• The PerformanceResourceTiming HTMLFormElement gained a method requestSubmit(), which acts like pressing a button to submit data.
• Web Animations API:
  • Support for the getter Animation.timeline, as well as Document.timeline, DocumentTimeline and AnimationTimeline.
  • Support for methods Document.getAnimations() and can.
• Developer tools:
  • Instant computation of console expressions allows developers to see the result immediately as they type.
  • The tool for measuring pages has learned to resize a rectangular frame.
  • Inspector now allows using not just CSS selectors for searching elements but also expressions XPath.
  • regular expressions WebSocket using A new setting view_source.tab_size has been introduced, allowing you to specify the tab length in the page's source code view mode..
  • Monitoring network equipment via SNMPv3 in Zabbix
