I've always had the problem that I could never settle on one web browser to use exclusively, in fact I had three, but now with a little bit of engineering I think I can finally settle on Firefox. The complaint that I've always had with browsers were their download and search limitations in that I couldn't really specify where I wanted certain files downloaded to or really search the websites I wanted to. However, now with Firefox extensions and hacks that's all become a thing of the past! First, I use the Firefox extension Download Sort 2.5.3 to control my downloads. Second, is the Attack of the Show Firefox/google search hack that allows you to search websites through google. Both these utilities can be tweaked to your heart's desire, and the links are provided below.
