How can I get a warning if I close Firefox 4 whilst a download is it progress - I thought I had this in FF3.6.

How can I get a warning if I close Firefox 4 whilst a download is it progress - I thought I had this in FF3.6.

Chosen solution

You can set the pref browser.download.manager.quitBehavior to 2 on the about:config page.

That will make Firefox ask for confirmation if you want to cancel the download if you close Firefox.

See:


To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
