How to improve image quality in Firefox when using Sprint Tethering? Ever since I got my android, and switched to sprint, when I use Firefox, all of the images loaded are just horrible in quality, like almost to a point you can barely tell what it is.

I hear that it has to do with the data provider, routing traffic through a proxy that modifies the HTTP header with some Javascript that compresses the images to preserve bandwidth. 

EDIT: I found the script. Used on EVERY page that is loaded, in the title: 

&lt;script src="http://1.2.3.4/bmi-int-js/bmi.js?version=1332944399" 
        language="javascript"&gt;&lt;/script&gt;


This is what I need to figure out how to block!

When I hover my mouse over an image, it says "Shift+R improves the quality of this image, Shift+A improves the quality of all images on this page". 
So I try that and even that wont work for me. 

I wouldnt mind this if I could take care of the situation when I needed to by pressing those keyboard shortcuts (Shift+A/Shift+R) but since it doesnt work for me, I am kind of stuck on what I should do about it..

Is there anyway to get around this? or a way I can fix the keyboard shortcuts to actually work?

Im a web developer so I kind of need my images to render correctly as I need to actually preview my layout and see if my pages are rendering satisfactory, but I can't do that if my images look like junk all the time. 

This happens on every page by the way, but I noticed it only happens to images that are embedded using the image tag &lt;img src=""&gt;&lt;/img&gt;, and it doesn't happen to images loaded via CSS. .image { background-image: src="", etc; }.

Also I noticed the shortcut keys work on Firefox on Ubuntu 12.04 (just barely), but it is not working for me now in Windows 7.

So is there a way I could go into the about:config and change some values to prevent this? or a counter script, or ever something on my phone that will prevent this? 

Any thoughts on this would be great, I would really greatly appreciate it. I mean its a nice feature, saves on bandwidth and all, but Its ridiculous just how bad the image quality can be, pixelated as can be, without a way to fix it.
Would the same thing happen if you used a VPN? Your ISP wouldn't be able to compress images if it didn't know what the traffic was, right?

I found setting up a basic VPN to be pretty easy; if you have a Win 7 PC with an internet connection (or a willing buddy with one) you can set up a quick VPN using this guide: How to Configure your Computer to Accept Incoming VPN Connections in Windows 7. With that working, try connecting to your VPN both from your tethered laptop and from the Android phone itself. If it works you could investigate a more permanent VPN solution.
