After my previous Opera 10 tip, here’s my next one which Opera 10 users would be interested in.
Opera 10’s Speed Dial feature is now more of like Chrome’s because it now opens with every new tab and it now offers more options to customize it. Like increase the number of columns and rows which was previously only possible manually.
Greasemonkey is a Firefox extension that allows Firefox users to install scripts that make quick changes to web pages. Greasemonkey can be used to add new functionality to web pages and web sites like adding an HTML signature in Google, bypassing image verification in Orkut etc.
