To adjust the default Browser internal Juno Eclipse to run the application

Good evening, everyone

I’m having a hard time running the application from within Eclipse vaadin TouchKit Browser, already configured the safari, firefox but it shows the error message in the image below.

Thank you,

So, either:

make sure your page / server doesn't try to enable Chrome Frame on the client
compile for ie8 and safari (2 permutations): <set-property name="user.agent" value="ie8,safari" />
uninstall Chrome Frame
or if it's only to speed up iterations while developing/testing your app, only compile the safari permutation
