XPI link.

Reproducible: Always
Steps to Reproduce:
1. Open about:config and set Filter to "xpinstall".
2. Set xpinstall.whitelist.add to default
   ("mozilla.org, mozdev.org, texturizer.net").
3. Open testcase attachment 149724 [details] (from Bug 240552) in new browser window.
4. Click on the first http link and wait until XPI confirmation box appears.
5. Examine "xpinstall.whitelist.add" in about:config window.
6. Click "Cancel" in confirmation box.

Actual Results:  
xpinstall.whitelist.add now empty

Expected Results:

Steps above can be reproduced also for xpinstall.blacklist.add.

that's fine. this is a command, not a permanent pref, and the entries are
actually stored in permission manager.
