This update for MozillaFirefox, MozillaFirefox-branding-SLE fixes the following issues:

Changes in MozillaFirefox and MozillaFirefox-branding-SLE:

This update provides Firefox Extended Support Release 115.0 ESR

• New:

  • Required fields are now highlighted in PDF forms.
  • Improved performance on high-refresh rate monitors (120Hz+).
  • Buttons in the Tabs toolbar can now be reached with Tab, Shift+Tab, and Arrow keys. View this article for additional details.
  • Windows' 'Make text bigger' accessibility setting now affects all the UI and content pages, rather than only applying to system font sizes.
  • Non-breaking spaces are now preserved—preventing automatic line breaks—when copying text from a form control.
  • Fixed WebGL performance issues on NVIDIA binary drivers via DMA-Buf on Linux.
  • Fixed an issue in which Firefox startup could be significantly slowed down by the processing of Web content local storage. This had the greatest impact on users with platter hard drives and significant local storage.
  • Removed a configuration option to allow SHA-1 signatures in certificates: SHA-1 signatures in certificates—long since determined to no longer be secure enough—are now not supported.
  • Highlight color is preserved correctly after typing Enter in the mail composer of Yahoo Mail and Outlook. After bypassing the https only error page navigating back would take you to the error page that was previously dismissed. Back now takes you to the previous site that was visited.
  • Paste unformatted shortcut (shift+ctrl/cmd+v) now works in plain text contexts, such as input and text area.
  • Added an option to print only the current page from the print preview dialog.
  • Swipe to navigate (two fingers on a touchpad swiped left or right to perform history back or forward) on Windows is now enabled.
  • Stability on Windows is significantly improved as Firefox handles low-memory situations much better.
  • Touchpad scrolling on macOS was made more accessible by reducing unintended diagonal scrolling opposite of the intended scroll axis.
  • Firefox is less likely to run out of memory on Linux and performs more efficiently for the rest of the system when memory runs low.
  • It is now possible to edit PDFs: including writing text, drawing, and adding signatures.
  • Setting Firefox as your default browser now also makes it the default PDF application on Windows systems.
  • Swipe-to-navigate (two fingers on a touchpad swiped left or right to perform history back or forward) now works for Linux users on Wayland.
  • Text Recognition in images allows users on macOS 10.15 and higher to extract text from the selected image (such as a meme or screenshot).
  • Firefox View helps you get back to content you previously discovered. A pinned tab allows you to find and open recently closed tabs on your current device and access tabs from other devices (via our “Tab Pickup” feature).
  • Import maps, which allow web pages to control the behavior of JavaScript imports, are now enabled by default.
  • Processes used for background tabs now use efficiency mode on Windows 11 to limit resource use.
  • The shift+esc keyboard shortcut now opens the Process Manager, offering a way to quickly identify processes that are using too many resources.
  • Firefox now supports properly color correcting images tagged with ICCv4 profiles.
  • Support for non-English characters when saving and printing PDF forms.
  • The bookmarks toolbar's default 'Only show on New Tab' state works correctly for blank new tabs. As before, you can change the bookmark toolbar's behavior using the toolbar context menu.
  • Manifest Version 3 (MV3) extension support is now enabled by default (MV2 remains enabled/supported). This major update also ushers an exciting user…

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. (CVE-2023-37201, CVE-2023-37202, CVE-2023-37205, CVE-2023-37207, CVE-2023-37209, CVE-2023-37210, CVE-2023-37211, CVE-2023-37212)

Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. (CVE-2023-34414, CVE-2023-34416, CVE-2023-37201, CVE-2023-37202, CVE-2023-37207, CVE-2023-37211)
