Which "search" was changed?

There's three places in Firefox which you can do a search from:

1. the Search Bar
2. the Location Bar
3. the searchContainer on the default about:home homepage

Greetings

I am not up on the terminology. The second line on my screen has the forward and back arrows followed by "Go to a web Site" in a box followed by a second box that used to read Google but now reads Ask.com. I want to change this back to Google.

Thanks

Ralph
