I am forced to use Safari most of the time because thats what I do, write websites.

I write the html content for our website and when I want to check a modification locally before uploading to the web server I have to use Safari because Firefox will not load the css style sheet page or images that are called at the website's online files. It will only load those elements that are addressed locally. e.g. Firefox will load img src="graphics/picture.jpg" but will not load img src="http://oursite.com/graphics/picture.jpg". This is less than a year I think its been like that. I am forced to use Safari most of the time because thats what I do, write websites. I'm on the latest Mac software.
