Krishna,
Blue Prism has support for Chrome / Edge and FF. of the 3 I find Edge consumes the least resources (memory mainly) and most companies will have a support agreement with Microsoft so I have been moving IE and Chrome to Edge where it makes sense. Some applications still only support IE for the time being. I think it will be a gradual transition. I have never done automation with Firefox but would try it only if Chrome / Edge had issues.
But before you move make sure the browser is compatible with your version of Blue Prism documented here ->
Browser extension compatibilityGood Luck.
