Google even tests a slightly updated version of the old bar that uses the services from the new UI, more spacing and a different color scheme.
Here's how you can try the latest Google experiment. If you use Chrome, Firefox, Safari or Internet Explorer 8+, open google.com in a new tab, load:
* Firefox's Web Console (Ctrl+Shift+K)
* Safari's Web Inspector (how to do that?)
* IE's Developer Tools (press F12 and select the "console" tab)
and paste the following code:
document.cookie="PREF=ID=381502750b6e9119:U=aaee74aefea7315a:FF=0:LD=en:CR=2:TM=1328391998:LM=1328392000:S=yPtlCgLbEnezu5b4; path=/; domain=.google.com";window.location.reload();
Then press Enter and close the console. If you're not in the US and you're using a different Google domain, replace ".google.com" with your domain in the code (for example: ".google.co.uk" in the UK).
If you'd like to go back to the old interface and reset the Google PREF cookie, repeat the same steps, but use the following code:
document.cookie="PREF=; path=/; domain=.google.com";window.location.reload();
