RT and firefox 1.0.1

I’m making progress by leaps and bounds now!!!

This is sort of nitpicky, but does anyone know why the bestpratical.com logo
image does not appear in the upper left of the firefox 1.0.1 browser? It
works fine with IE, but not firefox.

Thoughts on this anyone?

In my experience this relates to an authentication issue.
Firefox/Mozilla trys to be smart about page components that it grabs,
and if it is trying to get an image and the MIME type is not an image
then they abort. I’ve had the same issue with style sheets and
javascript pages. IE on the other hand just grabs everything and hopes
that things turn out right.

To see if this is the issue:

Tools->Page Info
Media Tab
Select /NoAuth/images//bplogo.gif
Check to see what the Type is.

If the type is not image/gif then it is likely that your auth mechanism
is interfering.

The logo works fine on the RT server at my job (RT 3.0.2) with every
browser I’ve tried – Firefox, Safari, IE, Opera, OmniWeb, Camino…

What does the HTML look like from your RT instance? Can the URL in the
tag be otherwise accessed by Firefox? (I.e. can you cut & paste
that URL directly into the browser?)

It appears in my Ff-1.0.1.

You might want to look at the link for the image. IE can handle back
slashes, but firefox cannot. Matt

It is image/gif.

Any other thoughts?

Well you can try to see if you can get the image at all.

In Firefox right click on where the image should be and select “View
Image”. This should call up the gif in the window – and should allow
you to see it if you go back to the main page (though only for this
session).

But before you do that you might want to turn up the debuging messages
for your webserver, just to see what it logs for the request.

Before I go cranking up the logging on apache…

I can not see the picture if I right click and say “view image”. What I do
see is a bunch of garbage characters. This is the case under Linux and
Windows.

Hm… seems like the .gif is getting munged. I can think of a couple
ways that this is happening:

  1. .gif display is messed up in your instalations – seems unlikely as
    you would be seeing undisplayed images on most websites.
  2. The negotiation for the image is messed up.

I’d try saving the image to disk from IE, then try opening in Firefox.
If you can see the image then it is the negotiation, if not then there
is a serious image display issue.

If the problem is the negotiation, then again I’d ramp up Apache loging
as high as it goes and do a transaction. Just a guess – Apache might
be trying to negotiate compression on the image.

Ah.
I think there’s something in the archive or the wiki about this:
The gif is being interpreted (or tried to) by mod_perl.

Review your apache-configuration.
Works for me: RT3.4.1, Firefox 1.0.1, Opera 7.54

Look at Tools->Page Info->Media->Type for the file in question. If it
seems insane, the mimetypes on your Apache are hosed.

Well, here’s some info for you all on this.

I copied a different gif into the place of bplogo.gif. In fact it was the
apache feather logo from the online manual. It shows up just fine. That
tells me the problem isn’t in software, but rather the image in some way.

I’m going to try to open the image in an editor and save it again. Maybe
the image has some kind of fault, that I happen to stumble on.
