Firefox extension to grab RIS entries from websites and library search portals & web clipping!

Grabbing entries from Google Scholar or other sources can be a counter intuitive exercise: download, open the library, etc. Wouldn’t it be better to have a Firefox addon for importing using site translators the way Zotero does, including the ability to grab multiple entries that show up on a page? Also, the ability to grab web pages or clips from sites and instantly create a corresponding bibliographic entry would be mind blowing. The library search feature in EN seems to me to simply replicate the search function already available at library sites and it makes you grab stuff before you can even have a look at it. It would be much better to permit importation of bibliographic data once you have found what you want using the search engine native to the site in question.
