When you try to call InstallTrigger.getVersion(<extn. name>) in javascript from
a webpage to check if a specified extension is installed, the function always
returns null even if the exnteion is properly installed. The installed extension
is displayed by extension manager and works as expected. 

Reproducible: Always

Steps to Reproduce:
1.Install an extension (xyz.xpi) which has install.rdf and all relevent files.
2.Verify that the extension is installed using exntesion manager and is
functioning as expected.
3.Now from a test html page, in javacript code, try to see if the extension
version by calling InstallTrigger.getVersion(). InstallTrigger.getVersion()
returns null.

Actual Results:  
InstallTrigger.getVersion() returns null.

Expected Results:  
InstallTrigger.getVersion() should have returned the version which I specified
in install.rdf.

Perhaps we should drop the old xpinstall install registry for the new toolkit
and use the EM to provide this information (xulrunner will have a similar
registry of installed applications).

This is a feature, since the getVersion thing never was intended to work for
extensions, only old-style XPIs.

This would only be allowed if the site is in the whitelist and allow sites to
install software is enabled... true?

Adding the site to whitelist does not solve the problem. I even tried by copying
the html file on to local machine and checking if it returns the version, but no
luck.

I didn't think it would. I was verifying that these calls would respect these
settings since if they didn't any site could get this info without the user
granting the site the priv or the user knowing it.

InstallTrigger.getVersion() does indeed respect the install whitelist, and
should for privacy reasons. As noted in comment #1 though this is intimately
tied to the (old-style) xpinstall version registry which is bypassed by the new
install.rdf extension manager stuff.

It would be useful to tie the two, though (while still respecting the whitelist)

InstallTrigger.getVersion no longer exists.
