Do you hate it (like I do) when you click a link and a website opens a new browser window without the address bar, toolbar, bookmarks, scroll bars etc … and you can't even resize the window?

Banks are particularly annoying like this… despite the fact that their websites are designed to work on screens as small as 800×600, they have code in their login routines that maximises the internet banking window, even if you're running a high-res display like a 24".

Here's a hugely useful tip about how to reconfigure Firefox to stop websites doing these annoying things.

1. Open a new tab in Firefox. In this new tab, type about:config into the address bar.

2. Copy and paste this text into the filter box: dom.disable_window_open_feature.

3. Double click each of the items that appears in the list to change the default behaviour. (See the tip referenced above for more detailed info on what each of the list items does.)
