Comment 7 for bug 240312

Let's keep things straight here. There are two pieces of software out there that, as I understand it, do slightly different things. First, came the prism application. This is software is in the Ubuntu repositories and allows you to set up prism 'webapps' and is standalone from the browser. The second software is a Firefox extension. With this extension, you get a menu item added to firefox's tools menu that allows you to take the webpage you are on and convert it into a prism webapp.

Indeed, I have the ubuntu standalone prism package from the repos and it works fine. It is the prism extension installed from, https://addons.mozilla.org/en-US/firefox/addon/6665 , that causes the crash. The issue may be related to the fact that the application from the repos is prism 0.8 based and the extension is based (as far as I know) on 0.9. I have not tried to create a new profile to see if the extension works with a new one. Regardless, it is a bug IMHO.
