Sometimes pop-up windows are too baby to affectation all their content, and they are not consistently resizable by default. After some research, I begin that in Firefox you can override this behavior by alteration one of the abounding user preferences.
To accomplish them consistently resizable:
Method 1
type about:config in the Location Bar and columnist Enter. Find dom.disable_window_open_feature.resizable . Double click the entry to Change the boolean value from false to true
Method 2
This extension makes all popup windows resizable.
