Need an add-on to force ALL pop-ups into same widnow

Question

I sometimes overlook pop-up windows because of their location on the screen. The result is that I may accept or deny something inadvertently. Is there a Firefox add-on – or can someone create one – that would force all pop-up windows to display in the same centrally located box, preferably in the middle of the screen, so that these messages can be spotted?

Answer 1

I don't think there is such an add-on, but you can make pop-ups open in a new tab instead and see how that goes.
# Type ''about:config'' into the address bar and press Enter.
# To bypass the warning, press the big button labeled "I'll be careful, I promise!".
# In the search box, paste ''browser.link.open_newwindow.restriction''
# In the search results, double-click ''browser.link.open_newwindow.restriction'' and set its value to '''0'''
# In the search box, paste ''browser.link.open_newwindow''
# In the search results, if ''browser.link.open_newwindow'' isn't at its default value of '''3''', right-click it and choose Reset.
If you prefer controlling the above with an add-on, Tab Utilities Lite is an option.
