After the launch of Firefox 4 the context menu for links had its first two items swapped.
Many people ended up having to open new window over and over again as they were used to the old order of the items.
This addon does a simple thing. It swaps the position of "Open Link in New Window" and "Open Link in New Tab" items so it is back to pre-Firefox 4 order.
Install it and get rid of all those new windows opened by mistake!
