This likely will be the leap of Mozilla Foundation that it will turn mobile and directly compete with the other major mobile browser -- Opera Mobile, Opera Mini, Windows Internet Explorer Mobile, Safari for iPhone OS, S60 Web Browser, Blackberry Web Browser -- although it will not come on iPhone and Blackberry due to anti-compete policy from the vendor, just like Opera Mobile and Opera Mini (although Opera Mini pass this on Blackberry.
Okay, this time I will test the Mozilla Fennec. How it looks and the interface is. As usual, I will give you some screenshots. On the left side, a pretty pic from Firefox for Mobile's Fan Page on Facebook have a nice meaning, lol.
Actually, Mozilla Foundation have a version for Windows, Mac and Linux for testing purposes or to develop add-ons. You can download it here.

After Startup
The Awesome Bar
Lol, they made a new terminology to replace Adress Bar. I just don't find where is the awesome. It's not like Microsoft which changed Taskbar into Superbar in Windows 7 that is trully super.

Awesome Bar after tapped. Awesome Bar replace the terminology of Address Bar which is the place where we input an URL Address like http://oginscorner.blogspot.com or just http://www.google.com.
The search is also here, a little bit like Google Chrome. Type the keyword on Awesome Bar, and tap the search provider on the bottom.
Tabbed Browsing
Huh, not special enough. But, if you want to see tab, just slide right till the end, and the tab will be shown.
Tab Pane. To open a new tab, just tap the New Tab Button on the bottom.
Navigation Pane
Back, forward, mark a bookmark and settings button is here. Just slide left till the end and navigation pane will be shown.

Navigation Pane.
Settings
Open Settings button in the navigation pane and you'll get:
Add-Ons
It's a great thing that the add-on is also on mobile. Fennec will be the first and only mobile browser with Add-Ons.
Downloads
This will be the place where you can see your downloads.

Common Settings Interface
I think you will understand by yourself.
Web Page Rendering
This web browser is not good yet, it can be proofed from it's perfomance on rendering from it's rendering of font size.

Too big, huh?
Zooming
As the other mobile web browser do same, this also come. The method is also same.

Zooming Feature.
Flash Integration
Yea, I don't know why but a flash plug-in should be added. Since it doesn't have a plugin yet, I'm not able to watch YouTube.
Conclusion
The features still common, but I'm interested with the add-on. It will be great, as great as Firefox do. We can waiting for the full release. But, you must be patient. The Symbian version is not previewed yet. The non-touch-screen interface is still proposed.
