How to check that a webpage / web application will look with Firefox at a specific screen resolution

Question

I have a task of testing a web application, which states that this application should correspond to a screen with a resolution of 1280 * 1024.

My work monitor is, however, a 20-inch screen with a resolution of 1680 * 1050.

Will resizing the Firefox window to 1280 * 1024 meet the testing criteria, or should I always change the resolution of my monitor? (Obviously, the second option is not preferred).

And also: is there a Firefox plugin that will help me set the window size accordingly?
