Stop webpages from resizing in Firefox
Have you ever visited a site, and all of a sudden your browser goes full screen? If you’re like me you like to use your windows at a specific size and not at the full screen size. I use a widescreen monitor, and most sites don’t use all the available realestate, so I size my windows. This way I can have a few of them open and displayed at the same time.
Here is how you can stop Firefox from resizing, so those annoying scripts can’t take control of your browser, and force you to view the site maximized.
Open up Firefox, and go to tools / options.

Select the Content Tab.

On the selection for Enable Java Script, select Advanced.

Locate the option for move or resize existing windows

On the Advanced Java script pop-up window, remove the check mark from “Move or Resize existing existing windows”.

Select “Ok”, and Choose “Ok” on the next window.

Now your browser will not be resized as you surf to new pages. This will not stop new windows (or pop-ups) from being opened to the maximum size, but your open widows will not be resized.
