I thought you could install one of the mobile browsers on your PC, think it was fennec maybe? Not sure if they still allow it though, they used to have a PC version so you could try to find bugs on there.

Go down to the Installation area and it gives you links to Linux MAC OS and Windows. I have never used it so idk, also this is the latest release and its still in beta so it will be buggy :P
