Mozilla今天将Mozilla Firefox 36.0 Beta送上了FTP服务器，新版采用Gecko 36作为内核，需要注意的是目前Firefox 36 Beta版分支还没有出现Windows 64位版本（从nightly版本上看目前性能依然没有调整到良好状态，预计Firefox 37会发展出稳定的产品），如有需要尝试的可以选用Developer Edition版本。预计正式版的Firefox 36将在2月中旬左右发布。 下载地址: http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/36.0b5/ 了解更多: https://developer.mozilla.org/en-US/Firefox/Releases/36 Changes for Web developersDeveloper Tools Highlights: eval sources now appear in the Debugger Simpler process for connecting to Firefox for Android Box Model Highlighter works on remote targets "Invert the call tree" option in the Profiler Inspect DOM promises in the console Extra "Paste" commands in the Inspector All devtools bugs fixed between Firefox 35 and Firefox 36.
