Firefox Tip: Restore the warning while closing multiple tabs


Mozilla Firefox has a really nice feature enabled by default. Firefox warns you when you press the close button while you have multiple tabs open. The feature is really useful against accidental presses on the close button. It is very useful to me personally as I have accidentally lost work in other browsers during several occasions.

For those who do not need such a feature, Firefox gives a checkbox at the confirmation (Exit and close tabs?) dialog – “Warn me when I attempt to close multiple tabs”. Now, if you use the feature and you have accidentally disabled it, then here’s how to get it back.

Under the Tabs heading, check the box before “Warn you when closing multiple tabs”.
