For every web designer & developer, refreshing the browsers to see the updates we make is a very common action.
XRefresh is a solution, specifically built for easing this process, which automatically refreshes browsers once an update to a file in our project folder is done.
It comes with 2 parts: a browser plugin (both for Firefox & IE) and an application (for Windows & Mac) which watches the changes made in the folders we mentioned.
Although it is handy for systems with one monitor, the best environment will probably be two monitors where the IDE & the browsers runs on each.
P.S. For Firefox, it requires Firebug to be installed.
Requirements: Firebug For Firefox
Compatibility: Windows & Mac
