Pale Moon - Release Notes** http://www.palemoon.org/releasenotes.shtml

26.1.0 (2016-02-16)

This is a web compatibility, stability and bugfix release.

Changes/fixes:

• Disabled our ES6 Promise implementation introduced in 26.0 since there were some severe issues with its implementation that caused a lot of inexplicable failures on websites. This means that some sites that insist on using Promises without checking availability and that do not provide sufficient web client compatibility by way of server-side libraries or polyfills will currently not work as-intended. Apologies for any inconvenience this may cause; providing a perfectly-working implementation will be our top priority going forward.

• Improved website compatibility with many sites and web applications by making our cookie gate less strict.

• Fixed web compatibility with Google Hangouts and Yahoo Calendar.

• Changed the memory allocator on Windows platforms to a much more modern full-library implementation of jemalloc, with miscellaneous additional fixes. This should give comparable speed to the system one and will allocate free memory more dynamically. This should fix issues like “huge animated gif choking” and inexplicable pauses when using many tabs, scrolling (extremely) long pages, or viewing media.

• Fixed a few rare crashing issues on Windows due to the build process.

• Reduced so-called “jank” on inner frame scrolling reflows.

• Extension compatibility: partial implementation of Firefox 26 download js modules as shims; this should make more Firefox extensions compatible with us out-of-the-box. (Thanks, Chaoskagami!)

• Added a “superstop” key combination (Shift+Esc) that will stop all (foreground and background) network activity, stop animated gifs, etc. even after the page itself has fully loaded (and the stop button not being available) - some web applications may not like this if you use it since it will also cancel XHR requests, etc.

• Updated NTLM authentication, deprecating v1 and adding a proper v2 implementation (Thanks, Trava90!)

• Updated the default theme to tweak/improve it some more (Thanks, Antonius32!)

Security fixes:

• Updated the Graphite2 font library to 1.3.5+ to fix a number of vulnerabilities (and some font bugs).

ブラウザのウェブ互換性（うまくページが表示できるかとか系）の問題が大トカゲ後ぽつぽつフォーラムに報告上がっていた件の修正が中心の様子っぱ Firefox系のアドオン方面も互換性少し良くなった気配

自分は国内のサイトでは不都合でたことはないんだけど 海外サイトでちょっと・・ID/PASS正しく入力しても無限ループするような不具合が出るサイトがあってちょっと困って一時的に他のブラウザーで開くハメになったっけのぅ・・・（今回治った気配）

ともあれセキュリティアップデートも含まれるので更新忘れずにのぅ

かっぱでしたっぱ♪
