User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.57 Safari/536.11

Steps to reproduce:

# Build b2g on tip from 7/31/12
# Setup for debugging as per this thread!msg/
# Start b2g and verify debugging port listening
# Start up-to-date Firefox Nightly (8/1/12), enable remote debugging, enable debug logging, connect

Actual results:

Following error is printed from Firefox Nightly:

  "from": "root",
  "applicationType": "browser",
  "traits": []
  "from": "root",
  "selected": 0,
  "tabs": [
      "actor": "conn0.tab2",
      "url": "chrome://browser/content/shell.xul"
  "error": "unknownError",
  "message": "error occurred while processing 'attach' request: TypeError: this._tabActor._tabbrowser is undefined",
  "from": "conn0.tab2"

Expected results:

It should have connected with debugging

Note, b2g refers to B2g desktop as per
Everything run on Ubuntu 12.04 LTS x86

Ugh, this is a regression from bug 751226, because it didn't take into account the changes in bug 751949 that I worked on at about the same time. I might had tested it before landing if I wasn't away on vacation, but we desperately need to run our tests against b2g. I'll have a patch ready, shortly.

Patch v1

This was the simplest solution that worked and I think the best. Bug 751949 doesn't concern b2g or fennec, so it makes sense to keep them oblivious to the web progress listener's presence.
