Sækja Mozilla Firefox (eo) 150.0

Version 150.0, first offered to Release channel users on April 21, 2026

New
- Split View just got better: You can now right-click any link and choose Open Link in Split View to open it alongside your current tab. You can also search open tabs when creating a split view and quickly reverse tab positions using the new Reverse Tabs option in the tab context menu.
- Share multiple tabs in a single step: select several tabs, right-click, and choose Share → Copy X links. When pasted into other apps, links include both the page title and URL for easy reading.
- You can now use Firefox’s built-in PDF editor to reorder, copy, paste, delete, and export pages in a PDF.
- Local network access restrictions are now being extended to all users. Firefox will require websites to request your permission before connecting to devices on your local network or to apps and services on your device. Previously limited to users with Enhanced Tracking Protection set to Strict, this protection is now rolling out gradually to all users. You can find more details about this on our support page.
- Try out real-time, private translations in Firefox Desktop with the about:translations page. Start typing the word "translate" into the URL bar for a quick-action shortcut to the page.

- Added support for the GTK emoji picker on Linux, allowing users to insert emoji using the system shortcut (typically Ctrl+.).
- Firefox web apps are now available to Windows users who installed Firefox through the Microsoft Store.
- The new Firefox Profile management system is now available to all users, including users on Windows 10.
- Backing up a profile to a file is now available to all Windows 10 and 11 users, including those who use the new profile management system.
- Firefox now ships with a new .rpm package for Linux users on Red Hat, Fedora, openSUSE, and other RPM-based distributions.

Fixed
- Fixed an issue on macOS where, when macOS Lockdown mode is enabled, emoji characters are not displayed in web content.
- Various security fixes.

Changed
- If you prefer creating tab groups from the context menu, you can now turn off drag-and-drop group creation in Settings > Tabs > Drag tabs to create tab groups.

Enterprise
- You can find information about policy updates and enterprise-specific bug fixes in the Firefox for Enterprise 150 Release Notes.

Developer
- A new element-specific section has been added to the pseudo-class toggle panel including a toggle for the :open pseudo-class, which is only available for elements that have an open state like <dialog> elements. The existing toggle for the :visited pseudo-class was also moved there, as it only applies to <a> and <area> elements. (Learn More)
- The Document.caretPositionFromPoint() method now only returns a position in a shadow DOM if its ShadowRoot is passed in the newly-added shadowRoots option.
- The devtools network monitor now indicates when a connection used a certificate issued by a certificate authority not in Mozilla's Root CA Program.

Web Platform
- Firefox now supports the ariaNotify API for accessibility notifications (e.g. for screen readers) as a more ergonomic and reliable alternative to ARIA live regions.
- Firefox now supports media element pseudo-classes (e.g., :playing, :paused) to allow more precise styling based on media playback state.
- Added support for the highlightsFromPoint() API, which allows web pages to interact with CSS Highlights by returning all Highlights at a given point.
- Firefox now supports light-dark() on images, just like on colors, which is very useful for supporting dark mode on websites.
- The color-mix() function previously accepted only two color values. This limitation has now been removed, allowing the function to accept an arbitrary number of colors.
- Added support for a new auto value on the sizes attribute for lazy-loaded image elements with multiple images defined via srcset. This allows the browser to automatically select the right image based on the layout width of the image element. (Learn More)
