This will be quick; Over the years I have used a lot of different browser to do my web development, but once google chrome came out it sorta dominated my destiny. I keep finding fun and handy features of the browser that makes life as a developer easier and easier.
Today I found a new one by accident I hadn't seen before -- If you have the developer tools open and click / hold the refresh button you are given different refresh options. Simple! A quick and easy way to get different refresh options for a site that you might be working on.
Note; this is apparently only a windows thing.
