Yes, there certainly is. It is a good practice to test your game out in all of the top 5 web browsers to make sure it runs good in all of them before releasing it to the public. Just download, and install them. Then start up Construct 2, click on your layout area, in your layout properties window click on project properties view, then scroll down to were it says preview browser, and select the browser you want to use.
@Wink is right, just change the 'preview browser' property in project properties, and it won't affect your default browser. It's always a good idea to test all major browsers though.
@edisone - there are many very small browsers which generally aren't used widely - I think you should only concern yourself with testing the five major browsers @Wink posted to save yourself some time and headaches.
Tnx for wink Ash,i'm using only Chrome and Palemoon,that's Firefox clone..it's built with same source,using same extension ,just more fast than the original one,so it's not properly a minor small browser..
