Question

By default in Firefox every time you open an image it will re-size to fit within the browser window, now if you view a lot of images this can become annoying having to click on the image every time it loads to see it full size.

There is a way to switch off that in about:config, but this is not a solution for a broader public.

Is there a way to switch that off by some JavaScript function, or CSS, or something else?

Answer 1

If you would like to switch off auto-resizing images in your browser, then you can

• type about:config
• search for property browser.enable_automatic_image_resizing
• and set it to false

If you want it for your visitors, I just can repeat what Jeremy Sydik writes in Design Accessible Web Sites,

it’s just their web, we’re building on it.

And in this case, you really shouldn’t decide whether your users want Firefox’s auto-resizing feature or not. You can always choose a solution that gives better user experience to your visitors. For instance, you may install a Lightbox variant as Daniel A. White already mentioned.

There is also great_llama’s solution to open images inside a HTML page.
