On about:newtab:

1. Choose a search engine that provides suggestions, like Google
2. In the search box, quickly type gibberish and press enter
3. Quickly open a new tab (Ctrl/Cmd+T)

If you're quick enough and the search suggestions take long enough to come in, then the search results URL loads in the newly opened tab.  It should load in the about:newtab tab.

ContentSearch._onMessageSearch has access to the xul:browser that requested the search (via, but instead it gets the top-level chrome window and uses it to load the URL (browserWin.loadURI).  That's dumb.  It should call loadURI on or something equivalent instead.  This should be pretty simple to fix.

Attached patch patch (obsolete) — Splinter Review
This is an embarrassing bug with a quick fix so I hope it's OK that I worked on it.

In case it's not clear, the reason for the `loaded` bool is to avoid silently catching errors thrown by recordSearchInHealthReport.  We definitely want to spot those.

This patch also fixes a JS strict warning introduced by bug 1036908:

JavaScript strict warning: resource:///modules/ContentSearch.jsm, line 211: ReferenceError: reference to undefined property data.selection

Review of attachment 8528525 [details] [diff] [review]:

I'd usually request a test (or to modify the existing test making it open a new tab when a search starts), but looks like in this case it may not be easily predictable the order in which open tab and search messages are handled in e10s mode?

nit: Just for code clarity, you could let browser =; at the top, and let win = browser.ownerDoc... here

I think it's simpler if you early "return Promise.resolve();" in the above catch... then you can avoid the loaded boolean.

[Feature/regressing bug #]:
Bug 962490, search box in about:newtab

[User impact if declined]:
This bug has been present since 31, but it became much easier to trigger after search suggestions were added to about:newtab in 34 (bug 1028985).  So so far, this bug has been easy to trigger in only one release.  If we let the fix ride the trains instead of uplifting it, the bug will be easy to trigger in the 35 and 36 releases, too.

[Describe test coverage new/current, TBPL]:
The fix comes with a new browser-chrome test.  Searching on about:newtab was already covered by existing related automated tests.

[Risks and why]:
Moderate risk given that this touches code related to searching on about:newtab, but the risk is mitigated by automated test coverage.  I ran the new test against both Aurora and Beta before requesting uplift approval.

[String/UUID change made/needed]:
