Komunitné fórum Firefox

If I want to display a table with large amounts of data and at the same time I want to pass it on via POST, Firefox displays only part of this data, What is the reason for this? In other browsers, these pages work without a problem.

so i need that "ctrl+shift+o" hotkey for my amd adrenaline. i tried googling on how to turn off/change hotkeys for firefox but i couldnt find anything that helps me find this hotkey setting.
