Firefox Problems Uploading/Viewing Images

[ZacFields]

Hello, I searched vb.com thoroughly looking for someone else who has this exact problem but I'm just not seeing anyone. I'm starting to feel convinced that there is a mod I'm using that is leading to this issue.

In Firefox only (IE and Chrome work fine), I am not able to use the standard image uploader to upload an image. I can select the file but once i click upload, there's a little red exclamation point and if I hover over it, I get the error in the first attachment.

Now if someone else loads an image and sets it as a thumbnail, the thumbnail won't show in Firefox but will just show a bunch of text (name of image, size, description for image).

The second attachment is a list of modifications on my forum. Anybody have any ideas or have run into any problems?

You need to present more information.

Which vbulletin version are you running and which version of Firefox you are using as your browser.

The simple way of figuring problems with mods is to disable them all and use your default skin and re-enable one by one until you find the source of your problem!

vbulletin 4.1.6 is the version I'm using and the Firefox version is the most current one as well.

I'm working on your recommendation of disabling mods but just wanted to check and see if this was something that was a known issue of a particular mod.

Here's the weirdest part of all this: If I get on Google Chrome and I upload an image to a thread (and can see that it works fine), I can hit view source and get the actual URL to that image and paste it in both Chrome and IE and it will show me the image. If I paste that URL into Firefox, it takes me to a page that says "Invalid Attachment specified. If you followed a valid link, please notify the administrator". For the same exact link!

I'll start peeling away mods but as you can see by my screenshot, I don't have any mods installed that aren't exactly "mainstream" mods. That's why I was hoping that someone would recognize this issue and know what the source problem is.

As a workaround for now, I've disabled thumbnails. Don't ask me why, but if the image is loaded full size into the thread it works just fine.
