Good, but needs improvement Rated 4 out of 5 stars
Good approach, similar to Chrome´s extension "Universal Search & IE8 Accelerators" (https://chrome.google.com/webstore/detail/hmcgifbelcmjecmkapejifljephjabjd)
But it´s conflicting with Google Dictionary and Google Translate (https://addons.mozilla.org/pt-BR/firefox/addon/google-dictionary-and-google-t/) as its popup mini windows are overlapping!
We can move the position of Cleeki pop-up windows, but the move is not persistent.
I would like to see a an option to choose the position (N, S, SW etc.) of the Cleeki´s popup window.
