How to see a warning upon closing Firefox while downloading a file

How-to, by admin.

While we browse the internet we sometimes forget that we are also downloading a file or a number of files and we exit Firefox. By default we see no warning that we are currently downloading something. Again, by default upon re-opening Firefox it will resume any downloading operations.That would be great, but sadly it’s not always helpful, since a lot of hosts do not allow to pause and continue downloads (rapidshare, megaupload, fileshare, etc.).

So, have you ever needed to see a notification box upon closing Firefox (regardless which version)? Follow the steps and you will always see the following image:

So, to see the window which will ask you to confirm when exiting from firefox while downloading a file, follow these steps:

1. At the address bar write  about:config.  When you get a warning click the button “I’ll be careful!”

2. At Filter write

3. Double click on Value and set it to 2!

4. Done!

Note: if it didn’t worked, restart Firefox and try again.

It should look something like this:


This solves the problem and you will be always asked if you indeed wish to close Firefox while a file is being downloaded currently.
