Despite my extensive searches on various online platforms, including stackoverflow, I have yet to come across a satisfactory answer to my question. While I find the window.history.pushState() and window.history.replaceState() methods quite user-friendly, it appears that they are only compatible with Chrome, Safari, FF4+, and IE10pp4+. Is there a method available that would allow me to achieve the same effect in IE8+ and FF3+ as well, rather than being limited to just FF4+ and IE10pp4+ (in addition to Chrome & Safari) ?
