Really the only reasons to use Internet Explorer are for developers to test what their sites look like on an older browser or if a company has business-critical apps that only work with the Internet Explorer browser.
Mewn gwirionedd yr unig resymau dros ddefnyddio Internet Explorer yw i ddatblygwyr brofi sut olwg sydd ar eu gwefannau ar borwr hŷn neu os oes gan gwmni raglenni sy'n hanfodol i fusnes sy'n gweithio gyda'r porwr Internet Explorer yn unig.
