841679 - Error Message on Console When Favicon File is Missing

Status: RESOLVED DUPLICATE of bug 282432

(Firefox :: Untriaged, defect)

Description

[Owen Leibman]

Attachment: A web page illustrating the problem.

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0
Build ID: 20130201065344

Steps to reproduce:

Access an html page with a link tag pointing to a shortcut icon file that does not exist.


Actual results:

Message written to Error Console in BOLD and without any relevant information as to what the missing file is.


Expected results:

Probably shouldn't issue any message (e.g. no message is issued for missing script or css file). If you do issue a message, it shouldn't be in bold (this is a particularly insignificant error), and there should be enough information in the message to allow the end-user to know what the missing file is.

I'm not able to reproduce the error message in the error console with the testcase you attached.

Could you try to reproduce it with a fresh profile, please? (don't import anything)

I created a new profile and ran Firefox using that profile. The message shows up on the error console with the new profile, exactly the same as the old one.

Interestingly enough, when I just open the attachment directly from the bugzilla page, I do not see any message in the error console. However, when I download it to my hard drive and open it from there, I do see the message once more.

And, when I start up Apache and use http://localhost to access the file, there is no message in the console. So, this problem seems to be restricted to pages opened with file: protocol.

Fixed in Firefox 19.
