1134422 - black window content

Status: RESOLVED INCOMPLETE

(Testing :: mozregression, defect)

Description

[dotnetCarpenter]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20150218005013

Steps to reproduce:

"mozregression --good 2014-10-13 --bad 2015-02-16" (64bit) and "mozregression --bits 32 --good 2013-10-13" both yield a firefox instance with black content window. Using the inspector, I can see that the HTML is there (downloaded and parsed) but no content is shown. Since I've tried to very different builds, I think this could be setting by mozregression.

Hmm, that's certainly not the behaviour we're seeing. :) What does the URL bar say the location is? If you navigate to some url like yahoo.com, what do you see?

Comment 2

It always black. Doesn't matter what URL. I've tried a few mozilla sites, codepen.io and dr.dk. Can it be a conflict with the profile for Firefox Developer Edition?

mozregression uses its own profile, so it shouldn't. Could you try downloading and running a standalone nightly from http://nightly.mozilla.org/ ? If that works out of the box, then there is indeed likely something wrong with the profile we're creating in mozregression.

When installing the nightly I get a warning about Firefox already running. At this point, I have Firefox 35.0.1 (released) and Firefox Developer Edition running.

After killing the processes for both Firefox 35.0.1 and Firefox Developer Edition, the nightly runs flawlessly.

Comment 6

[dotnetCarpenter]

I've uploaded two screen shots from when I install the nightly and when it is running. It works out of the box but only after I have killed the already running processes
Running "mozregression --bits 32 --good 2014-10-13 --bad 2015-02-16" yield the last screen shot: "nightly_mozregression.png".

Comment 8

[dotnetCarpenter]

Killing all firefox processes and retry with mozregression yield the same result. Only the "new tab" window shows anything.

Comment 9

[dotnetCarpenter]

Just use mozregression on ubuntu 14.10 on the same machine, without any issues.

Hm, is this the case for multiple builds ? It may be a firefox issue that was fixed.

This issue is quite old and probably not actionable.
