OK, i needed to download stuff from megaupload.com and i heard of the happy hour available from the megaupload toolbar that lets you have a premium account for a few hours to get your download needs done from 9 PM-3 AM. thats nice, and it works. however, it installed into both my internet explorer and firefox and was basically a piece of adaware:
1. changed all of my search preferences to yahoo
2. changed my 404 error page to advertisments by yahoo (like when you go to a site that doesn't exist it will send me to advertisments)
4. yahoo search box in toolbar
I uninstalled the megaupload extension in firefox from add-ons, and it is gone, but my search preferences are set to yahoo. i click the arrow and changed it back to google. the 404 error page is back to regualar too. however, in the address/location bar, when i type something in and press enter, it still takes me to yahoo search instead of google. reinstalling firefox is not an option as i have had it for a long time with a TON of add-ons and extensions to make it my own. All I want to do is change my default search engine to google, and no site on google tells me how, it only tells me how to change ie preferences to google, and other sites just tell me to select google on the search bar (which changes the search bar to google, but the address bar still goes to yahoo)> PLEASE HELP. I need it quickly too.
that is an image of this page, click the image, and it will send you to a slideshow of screenshots; first one is of this page, second is when i type google at the top, and third is what happens when i press enter after typing google.
