948380 - favicon doesn't show up when a version is given in the url

Status: NEW

(Toolkit :: Places, defect, P5)

Description

[elboulangero]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:25.0) Gecko/20100101 Firefox/25.0 Iceweasel/25.0 (Beta/Release)
Build ID: 20131102022523

Steps to reproduce:

I'm writing a webUI for an embedded device.

If I define the favicon like this:
<link rel="shortcut icon" href="resource/favicon.ico" type="image/x-icon">
It works.

But I'd like to give a version to this favicon, so that when I change it in the future, it will be automatically refreshed in the browser's cache.
So I do it like this (notice the v=1):
<link rel="shortcut icon" href="resource/favicon.ico?v=1" type="image/x-icon">

(I picked that trick from stackoverflow)
http://stackoverflow.com/questions/2208933/how-do-i-force-a-favicon-refresh





Actual results:

Without the v=1, it works (ie, the favicon appear in the tab).

With the v=1, it doesn't work on Firefox.
But it does work with other web browsers (Chromium, IE).


Expected results:

Am I correct with the v=1 ?

I don't know if it can be considered as a bug in Firefox, or if I'm wrong when I add the v=1 argument.

Please shine some light on this !
Thanks !

Hi Ioana,

thanks for the reply.

From my point of view it's a bug. Adding a querystring to the icon filename shouldn't break anything, and Firefox should display the icon anyway.

But I don't pretend to be an expert on this matter, that's why I don't claim high and loud that it's a bug.
I prefer to describe my use case, and let someone with more knowledge decide if it's a bug or not.

But I'm not asking for support here, I'm sorry if I didn't express myself clearly.

Best regards

We don't store the query string with favicons, so that may explain why it doesn't work in Firefox. If other browsers act differently we may look into why that's the case.

That said, Firefox expires favicons every 7 days or according to the cache settings, so it's not much time before it gets replaced when it changes, it's not stored forever.

Hi Marco,

> We don't store the query string with favicons...

I'm not sure to understand... But the problem I observe is not about a favicon that is not refreshed with the query string, it's about a favicon that is not displayed at all when a query string is part of the request. Maybe it was not very clear in my first post, sorry.

It's good to know, thanks for the info.

Best regards

Yeah, this may change things slightly, I'll leave this open for investigation, no ETA though for now since doesn't appear as a priority atm.
