I experimented with Prism before Windows and recently resurrected it under Ubuntu Linux 12.04 LTS using XFCE4 as the desktop.
One of the things I play with is TiddlyWiki, a personal laptop. TiddlyWiki is implemented in HTML, CSS and JavaScript and is contained in a single file. The problem is that recent changes to the browser security model violated it by setting limits on what could be done with things open from files: // URL. In current versions of Chrome, Firefox (my preferred browser), and Midori Tiddly complains that it cannot save changes and requires the Java applet as a plugin helper to save. (Oddly enough, it works in the current SeaMonkey: the browser displays a dialog box about possible insecure access and asks for permission, but as soon as it is indicated, it works as expected.)
Since I donβt need tabs to use and donβt need overhead for a full browser, Prism looked like a good solution, since the Gecko version implements the dates before changing the security model. I took the latest version 0.9 as a tar.gz file and extracted it in / opt / Prism. I put the empty.html file that you upload to TiddlyWiki and put it in / opt / TiddlyWiki. Then I launched the prism from the / opt / Prism directory. It will boot up and launch a configuration request dialog box. I pointed to the empty.html TiddlyWiki file. He created an icon on my desktop. Double-clicking on the icon raised TiddlyWiki in the Prism window, and everything worked as expected.
I'm not sure why Tracy had a problem installing under Linux Mint. Things only worked here under Ubuntu. The parsing error is similar to the problem I saw with the odd broken extension of Firefox. In order to eliminate the variables, I installed Prism in my own directory, carefully separated from the existing Mozilla material (since I have installed Firefox, SeaMonkey and Thunderbird, as well as releases and beta versions of Firefox.
Alas, the Firefox add-on is not a replacement. What it does is generate a configuration file for the website you point to that you can use with Prism. This is a convenience, but it is easy enough to create the resulting .webapp file manually.
