In Tor Browser, we found the graphics section was not getting display in the about:support page, and we saw the following error in the console:

Troubleshoot data provider failed: graphics
TypeError: loseExt is null  Troubleshoot.jsm:164
	snapshot resource://gre/modules/Troubleshoot.jsm:164:9
	onload chrome://global/content/aboutSupport.js:23:3
TypeError: invalid 'in' operand data  aboutSupport.js:279:1

To clarify I can reproduce this in standard Firefox by setting  "webgl.disable-extensions" to true. Updating title to reflect that.
Summary: Graphics section missing in Tor Browser about:support → about:support "Graphics" section breaks when "webgl.disable-extensions" is true
Here's the Tor Browser patch rebased to the latest mozilla-central.

I'd drop the comment to "This extension is not necessarily available."
