In typical web design fashion, there’s always something that doesn’t look quite right between two browsers. This one just completely lost me though.
I open the site in Safari. Everything is dandy.
I open it in Firefox. The entire page is displayed, just fine, but about 10-20% smaller. Images, fonts, divs. Everything.
Does this make any sense to anyone? Have you seen it or fixed it before? Is it just this browser? Is it me? Have I finally lost my mind?
You may have zoomed firefox’s view by accident, ctrl-+ will increase the size, ctrl-- will decrease the size. To reset it, hit ctrl-0.
As Brian has commented on this answer, you certainly shouldn’t rely on the size being the same, though I’m sure you’re aware of the perils of designing for a particular size. It’s good to know that you are seeing what you intended though.
