Firefox-Prevent webpages from resizing your browsing window

April 2018

Some webpages have the nasty behavior of resizing the Firefox browsing window. To prevent this from happening:
  • Open Firefox
  • Type "about:config" in the address bar and press Enter
  • Look for the following entry:
    • dom.disable_window_move_resize
  • Double click, to set its value to "True".
  • Restart Firefox.
