you want to know exactly when the tab is complete, right? in that case you can
do

function(_, _, tab) {
  if (tab.status == 'complete') ...

Actually, the only reason I had it was so that we'd only inject it once.  It
makes a lot more sense to just remove the listener though.  Removed whole thing.

remove listener here?

Done.

   chrome.tabs.executeScript(
       tabId,
-      { code: 'chrome.test.sendMessage("inject_scripts_all_hosts");' });
+      { code: "chrome.test.sendMessage('inject succeeded');" });

javascript can be so ugly. how about

chrome.tabs.executeScript(tabId, {
  code: ...
});

for some reason I didn't ask for that last time.

[Devlin, 2014/05/15 17:45:59]

Sure, done.

+  chrome.test.sendMessage('inject attempted');
 });
