Here is what i did in Firefox:
I already have Greasemonkey, if you need it, visit
Code:
https://addons.mozilla.org/en-US/firefox/addon/748/
Now to install Hide Google sidebar script for Greasemonkey:
Code:
http://userscripts.org/scripts/show/76203
If you have greasemonkey installed, you will see an "install" button on that page.
Click on it, wait for it to get installed. It worked perfectly for me
You dont have to restart your browser after installing scripts for Greasemonkey.
