Stop websites resizing Firefox window

Personally I find it a little annoying when websites resize my Firefox browser window, particularly when the website has a fixed width anyway! .. so I went looking for the option to stop this happening. It’s dead simple, just follow the instructions below and you too will have total control over the size of your browser window:

  1. Go to Tools > OptionsĀ  (Edit > Preferences for Mac and Linux users)
  2. Select the Content tab
  3. Click the Advanced button next to Enable Javascript
  4. Untick “Move or resize existing windows”
  5. Click OK, then OK again.

That’s all there is to it.
