Directs new tab page to it's own choice and cannot be changed. I've uninstalled it for that reason, NO addon or software in general controls what I do with my PC. I found search results nowhere near as good as Google or DuckDuckGo (which makes similar privacy claims) and heavily USA biased, despite setting my own country.
The redirction of my home page was the final straw. I found the add-on from another page and didn't check the reviews here. I wish I had, I wouldn't have even considered installing it if I'd known about the hijacking of my homw page.
Note to developer - you can see how unpopular the hijhacking is, you would do well to change it because it's a liability and will sink you.
