Status: RESOLVED WORKSFORME

Google Maps leaks when NoScript is installed.  (It seems very particular to Google Maps -- I use NoScript and I use leak-gauge, and Google Maps is basically the only site I see leaking.)

Steps to reproduce:
1. create a clean Firefox profile
2. install NoScript 1.6.5 from https://addons.mozilla.org/en-US/firefox/addon/722
3. restart Firefox with that profile to get extension installed
4. start Firefox with that clean profile and with NSPR_LOG_MODULES=DOMLeak:5,DocumentLeak:5,nsDocShellLeak:5,NodeInfoManagerLeak:5 NSPR_LOG_FILE=nspr.log in the environment and http://maps.google.com/ as the command line URL argument
5. run leak-gauge on nspr.log

Actual results:
Leaked inner window 1bdd260 (outer 120dda0) at address 1bdd260.
 ... with URI "http://maps.google.com/".
Leaked outer window 120dda0 at address 120dda0.
Leaked content nodes associated with node info manager at address 1bc3d80.
 ... with document URI "http://maps.google.com/".
Summary:
Leaked 2 out of 11 DOM Windows
Leaked 0 out of 40 documents
Leaked 0 out of 6 docshells
Leaked content nodes within 1 out of 49 documents

Expected results:
no leaks

Note that I first noticed this in a build that I shut down at or before 2008-04-14 00:36:48 -07:00 (which is the timestamp I have on the leak-gauge output).  I'm not sure if the regression was due to Firefox build changes or NoScript extension changes.
