I have found that Firefox uses less RAM than Chrome for my workloads. That being said, if you have limited RAM, the amount used by either is still extremely high. I suggest installing Auto Tab Discard [1] for Firefox or The Great Suspender [2] for Chrome. These will allow you to discard tabs and reload them later without closing them.
