RPMs for Firefox 3.7

English:

Firefox 3.6 is coming soon, nevertheless, I still can not see any TraceMonkey support for Linux x86_64. Compared with 32bit Firefox, 64bit edition of Firefox 3.5 and Firefox 3.6 are much slower than 32bit in the JavaScript benchmark. If you open tabs of Gmail and Google Wave and Google Reader, you will obviously feel that 32bit runs more rapidly that 64bit. So I choose Chrome/Chromium as daily-used web browser because they run fast enough. When I need to open an incompatible webpage or use proxy, I return to Firefox.

These days, I found out Firefox 3.7 x86_64 runs JavaScript much faster than previous version. Unlike Firefox 3.5 and Firefox 3.6, Firefox 3.7 gets TraceMonkey support for x86_64 platform. So we can see Firefox 3.7 has better performance. I try to run SunSpider benchmark in Firefox 3.5.5 and Firefox 3.7a1pre at the same system configuration. We can attain the strange benchmark result: Firefox 3.7 is about 1300ms while Firefox 3.5.5 is 4500ms. It hardly make another users believe it, nevertheless, it is true.

Unlike previous reports, Firefox 3.7 still keep a classical user interface. There is no change on it now. Later a new UI will be apply in Firefox 3.7. I download Firefox 3.7 from Mozilla FTP server and Build RPMs for i686 and x86_64. These are not native builds for Firefox 3.7, just repacking from binary archives. If you want to try it, please add my personal repo on fedorapeople.org. Download this file and put it into /etc/yum.repos.d/. Then you can install it via this command:

yum install firefox37

Firefox 3.7 will not cover Firefox 3.5. But actually they can not run immediately. I do not know why. I need some some guys to help me modify launch script. They seems to use the same profiles. Additionally, you should manually create a symbol for libflashplayer.so in /usr/share/firefox-3.7/plugins, Or put libflashplayer.so into /usr/share/firefox-3.7/plugins

At last, Firefox 3.7 is under development. I can not make sure that there is no bug in it. Please use it carefully.

Firefox 3.6即将到来，然而我一直看不到在64位Linux上有任何TraceMonkey的支持。对比起32位的Firefox，64位的Firefox 3.6和Firefox 3.5在JavaScript测试中要比32位慢得多。如果你打开Gmail、Google Wave和Google Reader的页面，你会明显感觉到32位Firefox会跑得比64位要快。所以我选择了Chrome/Chromium作为日常使用的浏览器，因为他们跑得足够地快。当我需要打开一个不兼容的网页或者使用代理服务器的时候，我会回到Firefox。

这段时间，我发现Firefox 3.7 x86_64跑JavaScript测试比早前的版本要快得多。不像Firefox 3.5和Firefox 3.6，Firefox 3.7在x86_64得到TraceMonkey的支持。所以Firefox 3.7拥有更好的性能。我尝试在同一系统配置下跑Firefox 3.5.5和Firefox 3.7 a1pre跑SunSpider JavaScript测试。我们会得到一个令人惊讶的结果：Firefox 3.7大约是1300ms，Firefox 3.5是4500ms。这很难让人相信结果，但是这确实是真实的。

不像早前的报道，Firefox 3.7一直保持着古典的用户界面。到现在都没有任何改变，稍候一个新UI将会应用在Firefox 3.7。我从Mozilla的FTP服务器下载了Firefox 3.7并且在i686和x86_64平台制作了RPM包。这不是原生编译的Firefox 3.7的RPM包，仅仅是重新打包了二进制压缩包。如果你想试用一下，请添加我的fedorapeople的个人源。下载这个文件并把它放置到/etc/yum.repos.d目录里。

yum install firefox37

Firefox 3.7不会覆盖掉Firefox 3.5。但是他们不能同时运行。我也不知道为什么。我需要一些人去修改Firefox 3.7的启动脚本。他们现在好像是使用相同的profiles。另外你应当在/usr/share/firefox-3.7/plugins目录内建立一个libflashplayer.so的链接，或者把libflashplayer.so放置到/usr/share/firefox-3.7/plugins目录，这样你就可以在Firefox 3.7播放Flash视频了。

最后，Firefox 3.7依然在开发中，我不担保它没有bug，请谨慎使用。
