Great for posters, invitations, banners, and other printed materials. https://i.meee.com.tw/WD9bbi6.png It is now possible to merge multiple PDFs by dragging a PDF into the PDF sidebar. It is now possible to add images as new pages within PDFs using the Firefox PDF editor. Quickly pick and copy a color from any page by typing "pick color", "color picker", or "eyedropper" in the address bar and selecting the "Pick a color" quick action. https://i.meee.com.tw/dtUscW5.png Added support for Apple's system-wide full-screen keyboard command (Globe-F).

Firefox now highlights the location permission icon in red whenever a website has access to your location. The permission icon is also now visible on search results pages where it was previously hidden. https://i.meee.com.tw/NGD5Ur3.png Smart Window: https://www.firefox.com/smart-window 。See and choose AI models directly from the Smart Window assistant. 。New Tab now includes a familiar address bar for typing websites and searching the web. https://i.meee.com.tw/MnhRylY.png Firefox Labs︰ Firefox Labs can now be opened quickly by typing "labs" or "experiment" in the address bar and selecting the Open Firefox Labs quick action. https://i.meee.com.tw/dH2QH6P.png Firefox now offers experimental support for the new JPEG XL image format, which generally provides better compression than WebP, JPEG, PNG, and GIF and is designed to supersede them. You can enable it from the Firefox Labs panel in Settings. https://jpegxl.info/ Fixed︰ Various security fixes. https://www.mozilla.org/security/advisories/mfsa2026-68/ Changed︰ Extensions can no longer access local files by default. Users can grant or revoke this access via the new "Access local files on your computer" permission, separate from "Access your data for all websites". Local Network Access restrictions are now enabled by default for all users. Firefox requires websites to request permission before connecting to devices on your local network or to apps and services on your device. Outdated cookie settings have been removed from the Settings UI. Users still in that mode should switch to default behavior "Isolate cross-site cookies". More information https://groups.google.com/a/mozilla.org/g/firefox-dev/c/dXvMLkzyFqM Enterprise︰ https://support.mozilla.org/kb/firefox-enterprise-153-release-notes Developer︰ Developer Information https://developer.mozilla.org/docs/Mozilla/Firefox/Releases/153 A new "Local Mode" setting in the options panel allows developers to load local directories via custom origins. This simplifies testing for APIs that do not function over standard file:// URLs, removing the need to run a local web server. Multiple directory mappings are supported. Web Platform︰ Firefox now supports a limited subset of the non-standard ::-webkit-scrollbar pseudo-element to improve web compatibility: 。Rules with non-zero width/height disable overlay scrollbars for the affected container. 。display: none on ::-webkit-scrollbar behaves like scrollbar-width: none, hiding the scrollbar. 。@supports selector(::-webkit-scrollbar) now evaluates to true. 。Full styling capabilities (colors, border-radius, etc.) are intentionally not supported. The vertical-align property was converted into a shorthand for baseline-source, alignment-baseline, and baseline-shift in Firefox 149. Now, alignment-baseline supports the new keywords alphabetic, ideographic, central, mathematical, and hanging, extending the variety of baselines to choose for alignment. https://mzl.la/4yzc8MP Implemented the new popover=hint spec, which removes a series of inconsistent and unexpected behaviors. https://github.com/whatwg/html/issues/12304 The circle() and ellipse() functions accept two new keywords closest-corner and farthest-corner for their radial size. https://mzl.la/4fn1mR1 https://mzl.la/4fwubdX The newly added Error.stackTraceLimit property allows to set the maximal depth of the captured JavaScript error stack as a performance optimization. https://mzl.la/4bVBQRY Developers can now use the text import attribute to import text files using the module system. https://mzl.la/4bzEWuM The Picture In Picture API exposes a way for web developers to make use of user agent Picture-In-Picture functionality. https://developer.mozilla.org/docs/Web/API/Picture-in-Picture_API The Intl.LocaleInfo proposal adds the ability to query Locale information, such as week data (first day in a week, weekend start day, weekend end day), text direction and hour cycle used in the Locale. https://mzl.la/4pxxOoE The MediaCapabilities.decodingInfo() and MediaCapabilities.encodingInfo() methods now accept the "webrtc" configuration type. This allows a site to query whether a given audio or video configuration can be decoded or encoded for WebRTC and whether doing so will be smooth and/or powerEfficient. -- 身在黑暗 心向光明 --
