Linux only: Run a browser directly from RAM with open source "app" ioSwiftFox. ioSwiftFox requires absolutely no installation and doesn't even require root privileges to run for the first time. ioSwiftFox is a simple script that after some chmod foo you can use to browse the web. ioSwiftFox runs faster than Firefox and even works with your existing Firefox extensions! If you want to get technical, ioSwiftFox is a recompilation of Firefox 2 for Infodomestic Objects. To get ioSwiftFox up and running, download the file and enter the following three commands into the terminal:

chmod + x ioSwiftFox2.0.0.6-pentium4_Infodomestic0.8.5
mv ioSwiftFox2.0.0.6-pentium4_Infodomestic0.8.5 ioswiftfox
./ioswiftfox

Make sure you do not have Firefox open when you run ioSwiftFox for the first time. ioSwiftFox is a great portable app for your thumb drive—talk about badass! ioSwiftFox is a free download for Linux only.

FOOTNOTE:
不好意思，我从lifehackercopy过来了，我现在系统不是linux，所以我实验不了，但是我直觉这是个好东西，你们有机会试试，然后和我分享

用了很久了啊，我用的是AMDK7的版本，这就是一个FIREFOX针对不同的CPU进行优化的一个版本。
是比FIREFOX快一点，但也不是很明显。

个人喜好，试试也无妨。

好明顯樓上說的是Swiftfox
但那個ioswiftfox明顯是不同的

是我看错了。
不过好像只有P4版本的，我实验不了。
