Re: Except Google is shite (and getting shiter)
It is a god idea to read their policy and permissions before installing. You may not be happy for a search engine to download stuff you haven't asked for and to open files on your PC. Or change what you get to see on a page. Not to mention the fact it wants permission to read all your username and password fields. It seems to have delusions of replacing/supplementing your adblocker, noscript and other plugins rather than just concentrating on providing search results.
Their intentions may be entirely honorable but some of the things you have to permit seem open to abuse, especially if a hacker adds extensions to the plugin. It is also not clear whether the plugin is active even when you are not specifically using ecosia for a search.
