Abrowser homepage problem

After I have updated Abrowser on homepage there is this problem:
Errore interpretazione XML: entità non definita Indirizzo:
jar:file:///usr/lib/abrowser/browser/omni.ja!/chrome/browser/content/browser/abouthome/aboutHome.xhtml
Riga numero 95, colonna 11:

----------^

I have the same problem (but in English).

There is a similar issue here:

I'm also having the same issue, but decided to follow the above issue.

There are two unrelated issues:

1) By default, unsigned addons such as AbrowserHome do not run. You can disable this behavior by setting xpinstall.signatures.required to false so that unsigned addons do run.

2) The Abrowser homepage isn't valid.

Any suggestion?
