This tip is mostly useful to people who operate their own websites. Site designers need to test the way their websites work in different screen resolutions, but its a pain to go and change your own screen resolution just to get your browser re-sized. There is a way around this by re-sizing your actual browser window to the size of the resolution you want to simulate. So, for example, if you want to see what your site looks like at 800×600, then you would size the browser window to 800 pixels wide and 600 pixels high.

OK, but how can you do this accurately? By taking advantage of the bookmark system. First create a bookmark of any website. This is just to create the entry. Next, right-click the bookmark and choose Properties. Change the URL to the following:

javascript:self.resizeTo(800,600);

Press OK. If IE warns you “The protocol ‘javascript’ does ot have a registered program…”, just hit Yes.

Now, just choose this favorite to auto-resize your browser. You can even make a shortcut to this bookmark to your Links toolbar for quicker access.
