Status: RESOLVED DUPLICATE of bug 1182083

Description

[Jordan Santell [:jsantell] [@jsantell]]

I think it's just for POSTs.

Works in:
27-4-2015 Dev Edition build (non-e10s)

Broken in:
11-5-2015 Dev Edition build (non-e10s)
11-5-2015 fx-team build (e10s)

STR
http://www.procata.com/cachetest/tests/posturi/index.php Go to  :
Open netmonitor, type in "firefox" (obvs), and hit submit.
Click on the POST just added in netmonitor.
Click on preview pane: empty

One data point: I'm not seeing this in nightly or on a local build

To clarify, I was able to recreate this in fx-team build (locally), and nightly from 5-5-2015

Jordan, any way you can get a regression range with mozregression?  Could be run with  `mozregression --good 2015-04-27 --bad 2015-05-05`.  Unfortunately I've been unable to reproduce.

Jeff, can you reproduce this?

I have a dev editon 40 build from today, I can repro in non-e10s & e10s. I see this warning when the preview pane is clicked:

No chrome package registered for chrome://browser/css/screen-cachetest.css

Here's a simplified test case for this problem.

The offending part in that file is the stylesheet which href is defined relative to the site root. Since the preview is populated by setting the frame innerHTML to be the response body [1], the base URL is not defined and the sheet URL cannot be resolved causing it to fail hard.

And for the record, this fails on release too.

Interesting. That file makes the preview fail to render if it's served from localhost but works fine via the b.m.o link. Anyways, that file might help to reproduce this or at least narrow down the cause which I'm not that sure about any more.

I ran mozregression and got to a point where it's bisecting commits from the first day. I don't think any of these work.

This is the same as bug 1182083 and as it contains more accurate information, I'm marking this as a duplicate. You can follow the progress on that bug.
