This browser is a safe and reliable, I would know since whenever i use it which is alot, I never have any problems, very fast and simple and easy, one of the best.
As far as I know, there is no taskbar available for the browser you are asking about. But maybe someone is working on it--seems like every day the above mentioned company comes out with something new...
It is now supposed to be the fastest browser.
And its also not efficient because there are some sites google chrome is not compatible with like www.gmx.com or www.coupons.com
