If your work requires HTML to be output, it's often wise to test it on just about every browser you can on every platform, and many developers do. I would if I could, but I don't work due to disability, so money is always scarce.
I wish they could just make a browser that combined all popular browsers into one as "views". That way you can use one browser, and switch between tabs.
