I have blocked Javascript alert messages on my Mozilla browser and now I want to turn them back on, but I can't figure out how. Does anyone else have this problem?

    Have you closed and opened your browser?

  • Go to settings restore default. That works for everything I guess.

  • @ Dr.Molle - when alert appears many times browser gives you an option(checkbox at the bottom of the alert message) to stop messages from showing. I checked that checkbox and now I don't get any alerts from that site, the problem is I need to see them.

Right click on webpage > select View Page Info entry > select Permissions tab > modify Show Notifications or Open Popup Window items to suit.

In modern Firefox the block is set for the current tab session.
So the easiest way is reopen the page in a new tab.

Note that closing and reopening tab restores its state and session, so it won't help!
You need to open new tab (or window).

Bonus tip: grab and drag the lock icon in the address bar and drop it next to current tab.
That will reopen current page in a new tab (and it will even use the same Firefox Container, if you use one).
