I have just came across a cool online tool which helps browser compatability testing by producing respective browser instances.
You have to first download and install a plugin. After its installed refresh the url and select the browser you want to open. It will then start the loading process which initially willl take 4-5 minutes afterwhich the browser opens and you can test pages just like the original browser. The next time you click for the browser it wont take time to load.
Currently i havent come across any bug or conflicts. test it out yourself and let me know if you find this usefull
