I use Firefox 8 and have Windows 7.
My problem isn't the navigation bar in the top right-hand corner of my screen, but when I try to use the search bar on my homepage. It used to just use Google, but now it uses AVG Secure Search. I have disabled the add in the Add-On Menu in the Tools Menu, but it did not do anything. I have already tried uninstalling AVG, but it did nothing, so I reinstalled it. I have also went into the about:config page and changed my keyword:URL to https://www.google.com/search?ie=UTF-8&oe=UTF-8&q=, as well as changing browser.search.defaultenginename to Google. Some one suggested changing browser.search.defaultURL, but that does not come up when I try to filter it. I have also removed AVG Secure Search from the drop-down list in the Navigation Bar in the top right-hand corner. I would really appreciate some help before I have to do a System Restore just go to get rid of this annoyance.
