Mozilla Firefox Version 105.0 Released with Security Updates

                 Mozilla sent Firefox Version 105.0 to the release channel today.  The update includes seven security updates of which three (3) are rated high, two (2) moderate, and two (2) are rated low.

Firefox ESR was updated to Version 102.3.

High

• #CVE-2022-40959: Bypassing FeaturePolicy restrictions on transient pages
• #CVE-2022-40960: Data-race when parsing non-UTF-8 URLs in threads
• #CVE-2022-40962: Memory safety bugs fixed in Firefox 105 and Firefox ESR 102.3

Moderate

#CVE-2022-40958: Bypassing Secure Context restriction for cookies with __Host and __Secure prefix

#CVE-2022-40961: Stack-buffer overflow when initializing Graphics

Low

• #CVE-2022-40956: Content-Security-Policy base-uri bypass
• #CVE-2022-40957: Incoherent instruction cache when building WASM on ARM64

New

• Added an option to print only the current page from the print preview dialog.
• Firefox now supports partitioned service workers in third-party contexts. You can register service workers in a third-party iframe and it will be partitioned under the top-level domain.
• Swipe to navigate (two fingers on a touchpad swiped left or right to perform history back or forward) on Windows is now enabled.
• Firefox is now compliant with the User Timing L3 specification, which adds additional optional arguments to the performance.mark and performance.measure methods to provide custom start times, end times, duration, and attached details.
• Searching in large lists for individual items is now 2x faster. This performance enhancement replaces array.includes and array.indexOf with an optimized SIMD version.

Fixed

• 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.

Update: To get the update now, select "Help" from the Firefox menu, then pick "About Firefox."  Mac users need to select "About Firefox" from the Firefox menu. If you do not use the English language version, Fully Localized Versions are available for download.
