Midori is the default browser in SliTaz. I am impressed after using it for some days. I have installed it in Ubuntu as well. It is not bloated like Firefox and opens much faster. Browsing is super-fast. Though it does not have numerous plug-ins like Firefox it has some that come along with it. It has its own script and ad-blocker which are sufficient for lame browsing.
To install the latest version on Ubuntu:
$ sudo add-apt-repository ppa:midori/ppa $ sudo apt-get update $ sudo apt-get install midori
