| Pale Moon 34.0.0 Jan 20, 2026 |
This is a new milestone release! There are many changes in this milestone; the most important ones are highlighted here. New features: Our default theme on Windows received a refresh and update. It should integrate better with Windows 11 now, and be more responsive to dark accent colors, among other things. Implemented WeakRef. See implementation notes. Implemented URL.canParse(). Implemented the inset-block and inset-inline CSS shorthands. Added a preference (privacy.forgetaboutsite.clearPasswords) to control clearing of passwords when using "forget about this site" in the permissions manager, and disabled clearing of passwords by default, since it was considered unexpected behavior by the community. Changed our JavaScript PRNG to Xoroshiro128++ to make it more robust while keeping high performance. Important updates and fixes: Re-landed CSS Cascade Layers support after the previous back-out. Re-landed CSS color-mix support after the previous back-out. RGB and HSL color spaces only, like previous. Implemented viewport overflow propagation logic. See implementation notes. Unprefixed CSS -moz-appearance; Pale Moon now accepts the unprefixed CSS appearance keyword. For compatibility, -moz-appearance and -webkit-appearance (if enabled) have been retained, although the long-term plan is to eventually remove the -moz prefixed one, so if you are an extension or theme developer, please consider switching your CSS to use appearance without a prefix. Fixed an intermittent but fairly prominent crash-to-desktop due to JavaScript garbage collection on certain modern sites. Fixed a crash on sites with certain types of CSP handling. Fixed a crash in WASM. Updated NSS to 3.90.9 (custom) to pick up several security and stability fixes. Updated ICU to v78.1. This is a major uplift for our internationalization subsystem, allowing further future developments for the Internationalization API. Updated Emoji support to Unicode 17. Updated our expat parser code to a more recent |

Disabled CSP reporting temporarily to work around memory issues caused by CloudFlare's scripting. While CSP reporting is important to inform webmasters of issues with their content security policies, not having the browser eat up all memory is more critical. We do intend to re-enable this when the issue is resolved on CloudFlare's side. Improved CSS grid performance to avoid exponential calculations and reflows caused by CloudFlare's scripting. This wasn't a bug, per se, but could easily lock up with bad scripting if called recursively. Added a few other small fixes that are tangentially related to the code changes made. |

Changes/fixes: Implemented a content sniffer for ADTS and raw AAC audio. Implemented AbortSignal.abort() and stub AbortSignal.timeout(). Unprefixed the :modal CSS pseudo-class and exposed it to content. Improved efficiency and performance of the Cycle Collector. Added a check for explicit expectance of a percentage value in CSS HSL for the S and L components. Updated the cookie storage database to no longer use BaseDomain. See implementation notes. Updated CSS grid handling to no longer apply auto min-sizing when flex max-sizing (browser parity). Updated the root certificates in the internal trust store. Updated the Public Suffix List (eTLD) in the browser. Removed no longer specced URL Constructor(DOMString url, URL base). Restored unofficial branding to what it was before ("New Moon" instead of "Browser"). Changed the default Firefox Compatibility user-agent version to 115.0. Fixed an issue where cloned <audio> or <video> elements would not respect the original element's muted state. Fixed a number of bugs and spec compliance issues in WebCrypto. Fixed installer application naming issue causing failure to detect running application. Fixed a crash when Interval handlers are present in scripts that are automatically terminated due to excessive runtime. Fixed a crash in JS Structured Cloning when the input would be bogus (CloudFlare-triggered crash). Fixed a crash in the XSLT stylesheet importing code. Updated NSS to 3.90.6 (custom) to pick up several security fixes. Security issues addressed: CVE-2025-1009. |
