Ask What’s the best way to test my membership site’s compatibility with different browsers?

[SuperAffiliateX]

I want to make sure my membership site works well on all browsers, but I don't know how to test it. Sometimes, things look fine on one browser but break on another. I have no idea what tools to use or what to check for. Do I need to test manually, or is there an easier way to do it? I want a simple process that helps me catch issues before my members do.
