Very interesting function ! Rated 5 out of 5 stars
This is an awesome add-on, far more interesting than the Speak word 4 add-on.
Some annoyances are :
1) There are two bars: the location bar and the keyword bar. That is very confusing. Moreover when I am typing a keyword is in the location bar and a preview displayed, the keyword bar doesn't work anymore. When will be the fusion between the two bars ?
2) It is required to have a very hight speed and what happens if it isn't not the case (low bandwidth, mobile keys ...) ? It must be instantly . I think that a detection of low connection to turn off automatically this function is a must
3) It is messy to use with the function Speak word 4 in the location bar
4) It would be wonderful to have also this function with the results of research of search engines
5) The location results bar is very small especially when there are a lot results. My suggestion: to give the possibility to the user to enlarge the location bar results with the mouse
6) The move with the mouse inside the location bar results is not practical at all
7) Why not integrate this function in a future version of Firefox?
