Orca Browser´s user-friendly interface brings a new level
of clarity and efficiency to your browsing experience,and
frequent upgrades have steadily improved its reliability.
Avant Browser is freeware That's right. 100% Free!.

Orca Browser contains a flaw that allows a remote cross site
scripting attack.This flaw exists because the application does
not validate properly the url links upon submission to the
bookmarks in browser:home page.
This could allow a user to create a specially crafted URL or a
bookmark that would execute arbitrary code in a user's browser
within the trust relationship between the browser and the server
wen try to load browser:home ,leading to a loss of integrity.
