I really like this addon. One problem? When I want to use Bing by typing bing.com in Firefox and doing any simple search through bing.com, this addon simply does not allow me to use anymore bing.com, that is I cannot get search results through bing.com!
There should be a quick option to temporarily be able to use bing.com to do various searches if I want to, at least for a certain period of time.
You could create a Bing2Google button in Firefox that acts like a toogle to enable and disable it. In the disable mode, I simply could do searches using bing.com without being prevented from doing so, as it is the case currently with this version of Bing2Google.
Many thanks to the developer to make this addon available.
