[提醒]Firefox 3.1最近的Nightly让Tab Mix Plus失效
应该是2008.08.19到20号之间的build取消掉了一个about:config键值,导致Tab Mix Plus失效。
要修正的话,在about:config里面添加回这个键值(布尔值) browser.sessionstore.enabled 设置为true 即可解决 |

蓝色的吉他:21号--22号改动了什么,JS性能一下子增加了10% 据说是一个什么TraceMonkey Tracemonkey is something like this: In any given javascript code there are some code-paths that are taken a lot more often than other code-paths. Tracemonkey traces or somehow learns which code-paths are typically followed, and then instead of having to interpret the javascript every time it comes across it, it stores a pre-compiled version instead. This pre-compiled path is stored as assembler (iirc), so instead of the javascript interpreter having to translate the javascript line-by-line every time it comes across it, when it hits one of these common codepaths the pre-assembled code will get used, resulting in quite a speed-up for the JS engine. 现在整个Tree都关闭中似乎是潜心落实TraceMonkey,昨天就几个更新,全部是Javascript方面的。 1. #446551 [Core:JavaScript Engine]-TM: js shell build failures on 64bit linux [Lin] 2. #450317 [Core:JavaScript Engine]-TM: Assertion failure in YUI code on upcoming.yahoo.com [Mac] 3. #450334 [Core:JavaScript Engine]-TM: TraceRecorder::forInLoop out of synch with js_Interpret [All] 4. #451154 [Core:JavaScript Engine]-TM: traces abort on Math.* method access [All] 5. #451242 [Core:JavaScript Engine]-Add fast-paths for dense array to uint/int/double buffers [All] 的确很彪悍。 |

据说设置True
javascript.options.jit.content javascript.options.jit.chrome 才是真正的有效。 根据测试 Firefox 3.1, 208ms IE7,816ms(已保证狂按N键取消警告) Opera 9.5,360ms |

javascript.options.jit. 默认是关闭的,打开后更快了,快太多了
版主能不能详细说说这两键值什么作用 |

打开这两个键值某些网页也出现了内存不能读或写或崩溃
测试SunSpider JavaScript有崩溃和脚本忙和假死的现象,但可以肯定如果能完成测试,成绩相对以往是很恐怖的 |

嗯,只开content不会崩溃了,谢谢KMC
![]() 开启之后的JS速度太恐怖了,比之前的版本快了几乎一倍! ![]() |

崩溃还是时有发生的,在Google Docs/Calendar这种Js heavy的页面尤其。
