Now might be as good a time as any for a few reminders. Trying to get rid of all "ads" is somewhat pointless and unrealistic. Many of the items discussed here might be seen as unnecessary ads by the user but from a content provider standpoint's, they are relevant and often crucial pieces of information.
What I gather from questions here is that many people are actually looking for a way to dynamically modify the information displayed by web pages, a completely separate matter from URL redirection.
There ARE browser-specific tools to "hide" web content but they typically require much more user involvement and only alter the display, not what is being actually transmitted. Research what extensions or addons are available for your particular browser and you might find suitable tools to be used in conjunction with AdAway, even though few are practical for mobile devices.
I know it's heresy to some, but sometimes the wisest approach is to ignore a few annoying display elements here and there. If AdAway keeps 99% of what you see on your screen relatively junk-free, you're doing fine. The Internet will never be totally tailored to your personal needs or wishes. Oh yeah, also remember that NOT using apps or sites that display too much garbage works fine too...
