To restore the clean and minimalistic theme of Google, you can use addons or scripts but unfortunately, they only work in Firefox. For Internet explorer or Chrome, there is no workaround to get rid of this effect. In such situations, GoogleSlim comes to rescue.
GoogleSlim lets you do the same search as in Google but without any animation or effects. Google does not affiliate it but there is no difference in search quality as it only provides a layer over the search engine keeping the same results. There are no excessive ads and it does not compromise search results. So, if you want to get rid of fade-in effect, use GoogleSlim. And yes it works in all browsers saving you trouble in installing Firefox addons or userscripts.
