Differing Window Size Between Browser Versions

Support
1

I was doing some tests with lazy loaded images and was noticing that in some browsers I would not get the same set of images to load in the results. Upon looking at the screen shots I found that different browsers had different sized screen shots.

Is it possible to have each browser version have the exact same viewport size?

If examples are needed I can provide them.

FWIW, the browsers are all sized to 1024x768. The actual viewport will vary based on how much of that the browser actually makes available to the page. Granted, it may make testing for identical content more difficult but that seems to be the more reasonable way to do it.
