Ubuntu 13.10 may be shipping with Chromium as its default web browser replacing Mozilla Firefox. For those who do not know, Chromium is an Open Source project and popular web browser Google Chrome is built upon it. Chromium is available in Ubuntu Software Center for the download.
In a discussion at Ubuntu Developers Summit, majority of developers favored Chromium over Firefox for several reasons. One of the foremost among them is that switch to webkit-based browser will provide consistency across various platforms (desktop, phone and tablet). Switching to Chromium will also enhance Unity Web Apps with the added advantage of ‘Chromeless’ state (currently the web Apps open in a ‘new tab’ rather than a chromless window). Since Chromium is already popular among users, the switch would not be an uncomfortable one.
The points, as discussed, that goes against Chromium are no in-browser PDF reader, inability to be build on all architectures, lack of support for Orca etc.
Even if Chromium is made the default browser, latest version of Firefox will be available to install in Ubuntu Software Center. You can see the hangout video of the UDC to get more details:
What you say of this move? Which one you prefer to be your default browser, Chromium or Firefox?
