Upscaled images look blurry, is there a way to sharpen them? In particular, zooming on pages with images that actually contain only text are hard to read.
I am zooming in on my homework in mastering physics. I am using a large screen and sitting far away. It uses a lot of images containing the text I need to read, but when the images are upscaled, they become very blurry and hard to read. A simple sharpen effect after it is resized would fix the problem. Is there a way to do this in firefox? like a command line switch or maybe something in about:config? Thanks

It may sound counter-intuitive, but could you try disabling graphics hardware acceleration? Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You usually need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
orange Firefox button or classic Tools menu > Options > Advanced
On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"
If you restart Firefox, is the issue resolved?
There have always been problems in Firefox with image that are scaled and not viewed in the native dimensions.
It is always best to scale images yourself to the desired dimensions and upload those images to the server.

FYI: Bug 486918 is fixed in Firefox 18
