All browser works fine here. Try clearing your browser's cache, possibly it will work. Else, the problem might be on your internet connection. Often times, when my connection is very sluggish, Roobet's site won't load.
My connection is Ok, like it said most websites load smoothly including exchanges but for the case of Roobet, the homepage loads well but after that, the whole browser just freezes. You can't even close the tab or window since the close button also becomes non-responsive until I just have to restart the computer.
I am going to try download a fresh Microsoft Edge browser and try out since I only use Firefox right now.
I do have a few add-ons, Could they be the root cause?

Maybe his provider is blocking access to gambling sites include roobet.
I don't think it would be the case because the homepage loads well and freezes afterwards. So I thought maybe it was something to do with the website's script
