Blank Domain Modelling Page in Typo3 Extension Builder

Question

After installing the Extension Builder in Typo3 6.1 I only get a blank screen if I go to "Domain Modelling" page.

I tried to logout and login again as admin without success.

I cleared all caches with no success.

I don't see any fatals in my php error log?

What did I miss?

Answer 1

Looking into the Firefox Console I found lots of Javascript Errors. Seems to be related with this issue: http://forge.typo3.org/issues/48457

Using Chrome Browser instead solved the problem for me.
