This topic looks like it's still getting traffic, so I'll just provide some solutions to the possibilities I described above.
If you would like Google to be the Homepage, go to:
And click Ctrl+D (Windows) or Cmd+D (Mac)
If you would like Google Chrome to be your default browser, you will need to download and install Chrome. The download option includes a setting to make the browser your default browser. If you already have it installed, you will need to look in Chrome's settings for an option to make it your default browser.
If you would like to make Google your default search engine, if you're using the Search bar, you can just change the dropdown to Google. If you're using the URL bar ("Awesomebar") and the default is not Google, you'll have to do a little bit of manual settings editing in about:config. In a new tab, enter "about:config" into the URL Bar and, if necessary, click through the disclaimer that you'll be sure to be careful. Next, enter:
into the filter field. Double click the setting that appears and change whatever text is there to "Google".
I tried the about:config to get Google back as my default search engine to no avail. I followed your instructions exactly, but Babylon still pops up like a sore thumb.... I have uninstalled all babylon tools and programs and have restarted fire fox several times. to no avail. Please HELP!!!
