Added it and nothing. Cortana search box still uses Bing. If there is some way to make it work, please tell me -- or maybe add instructions on the addons profile.

TO THE DEVELOPER:
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.

I wrote this suggestion a while ago but so far nothing has been done. Please, developer wools, could you implement this suggestion? Thanks.

Many thanks to the developer to make this addon available.
