Mozilla Firefox - 更新履歴

89.0

New

  • Say hello to a fresh new Firefox, designed to get you where you want to go even faster.
    We’ve redesigned and modernized the core experience to be cleaner, more inviting, and easier to use.
  • Simplified browser chrome and toolbar: Less frequently used items removed to focus on the most important navigation items.
  • Clear, streamlined menus: Re-organized and prioritized menu content according to usage. Updated labels and removed iconography.
  • Updated prompts: Infobars, panels, and modals have a cleaner design and clearer language.
  • Inspired tab design: Floating tabs neatly contain information and surface cues when you need them, like visual indicators for audio controls.
    The rounded design of the active tab supports focus and signals the ability to easily move the tab as needed.
  • Fewer interruptions: Reduced number of alerts and messages, so you can browse with fewer distractions.
  • Cohesive, calmer visuals: Lighter iconography, a refined color palette, and more consistent styling throughout.
  • This release also includes enhancements to our privacy offerings:
  • We’ve enhanced the privacy of the Firefox Browser’s Private Browsing mode with Total Cookie Protection, which confines cookies to the site where they were created, preventing companies from using cookies to track your browsing across sites.
    This feature was originally launched in Firefox’s ETP Strict mode.

Fixed

  • Colors in Firefox on macOS will no longer be saturated on wide gamut displays, untagged images are properly treated as sRGB, and colors in images tagged as sRGB will now match CSS colors.
  • In full screen mode on macOS, moving your mouse to the top of the screen will no longer hide your tabs behind the system menu bar.
  • Also in full screen mode on macOS, it is now possible to hide the browser toolbars for a fully immersive full screen experience.
    This brings macOS in line with Windows and Linux.
  • Various stability and security fixes.

Changed:

  • Introducing a non-native implementation of web form controls, which delivers a new modern design and some improvements to page load performance.
    Watch for layout bugs in web pages that make assumptions about the dimensions or styling of form controls.
  • The screenshots feature is available in the right-click context menu. You can also add a screenshots shortcut to your toolbar.

Developer

  • Better keyboard navigation for editable BoxModel properties in the Inspector panel
88.0.1

Fixed

  • Resolved an issue caused by a recent Widevine plugin update which prevented some purchased video content from playing correctly (bug 1705138)
  • Fixed corruption of videos playing on Twitter or WebRTC calls on some Gen6 Intel graphics chipsets (bug 1708937)
  • Fixed menulists in Preferences being unreadable for users with High Contrast Mode enabled (bug 1706496)
  • Various stability and security fixes.
88.0

New

  • PDF forms now support JavaScript embedded in PDF files. Some PDF forms use JavaScript for validation and other interactive features.

  • Smooth pinch-zooming using a touchpad is now supported on Linux
  • To protect against cross-site privacy leaks, Firefox now isolates window.name data to the website that created it. Learn more

  • Screen readers no longer incorrectly read content that websites have visually hidden, as in the case of articles in the Google Help panel.
  • Various security fixes.

Changed:

  • Firefox will not prompt for access to your microphone or camera if you’ve already granted access to the same device on the same site in the same tab within the past 50 seconds.
    This new grace period reduces the number of times you’re prompted to grant device access.
  • The ‘Take a Screenshot’ feature was removed from the Page Actions menu in the url bar.
    To take a screenshot, right-click to open the context menu.
    You can also add a screenshots shortcut directly to your toolbar via the Customize menu.
    Open the Firefox menu and select Customize…
  • FTP support has been disabled, and its full removal is planned for an upcoming release.
    Addressing this security risk reduces the likelihood of an attack while also removing support for a non-encrypted protocol.

Enterprise

  • Various bug fixes and new policies have been implemented in the latest version of Firefox.
    You can see more details in the Firefox for Enterprise 88 Release Notes.

Developer

  • Introduced a new toggle button in the Network panel for switching between JSON formatted HTTP response and raw data (as received over the wire).
87.0

New

  • You’ll encounter less website breakage in Private Browsing and Strict Enhanced Tracking Protection with SmartBlock, which provides stand-in scripts so that websites load properly.
  • To further protect your privacy, our new default HTTP Referrer policy will trim path and query string information from referrer headers to prevent sites from accidentally leaking sensitive user data.
  • The “Highlight All” feature on Find in Page now displays tick marks alongside your scrollbar that correspond to the location of matches found on that page.
  • We’re proud to announce full support for macOS built-in screen reader, VoiceOver.
  • We’ve added a new locale: Silesian (szl)

Fixed

To re-enable the Backspace keyboard shortcut, you can change the about:config preference browser.backspace_action to 0. You can also use the recommended Alt + Left arrow (Command + Left arrow on Mac) shortcut instead.
  • We've removed items from the Library menu that weren't used often or have other access points in the browser: Synced tabs, Recent highlights, and Pocket list.
  • We've simplified the Help menu by reducing redundant items, such as those that point to Firefox support pages that can also be accessed via the Get Help item.

  • Developers can now use the Page Inspector to simulate prefers-color-scheme media queries, without having to change the operating system to light or dark mode.
  • Developers can now use the Page Inspector to toggle the :target pseudo-class for the currently selected element in addition to the pseudo-classes that were previously supported: :hover, :active and :focus, :focus-within, :focus-visible, and :visited.
  • There is a number of Page Inspector improvements and bug fixes related to inactive CSS rules:
    The table-layout property is now marked as inactive for non-table elements.
    The scroll-padding properties (shorthand and longhand) are now marked as inactive for non-scrollable elements.
    The text-overflow property was previously incorrectly marked as inactive for some overflow values.
