#### Markdown Here 2.13.2
The freeze has been fixed,
but this version hits the XML parse error below, on clicking [Setting] button...

```

#### Markdown Here 2.12.0
Thunderbird freezes on clicking [Setting] button of Markdown Here in Addon Manager.

Although, Markdown Here itself does work in mail creation screen.

Questa recensione riguarda una versione precedente (2.12.0) del componente aggiuntivo.
