Browser performance can vary quite a bit depending on the device, operating system, and how many tabs are open at once. I normally use one browser for most websites, so I rarely notice those differences unless I move to another computer. On my desktop, pages tend to load quickly, while my phone can sometimes take longer when the connection is busy. I’ve also noticed that an updated browser generally feels more responsive than an older installation. For online gaming sites, I think it makes sense to try the browsers already available on your own devices and see which one feels most comfortable. Small differences in menus, loading times, or screen layout can simply come from the browser or device rather than the site itself.
