I have Nightly installed on a laptop using Windows 7. I have been using it for nearly a year. This afternoon, when I tried to open Nightly, all I got was a small black window saying "close firefox." I used Chrome to get on the web, downloaded the most recent version of Nightly and tried to open it. Same thing happened. How do I get Nightly back?

Isisombululo esikhethiwe

Any particular reason that you use the (sometimes unstable) Nightly version, rather than a stable Release version of Firefox?

Nightly isn't intended to be "used", but rather for users to help the Mozilla developers by "testing" each new build and then reporting any Bugs or 'glitches' they may find. Nightly is between 12 and 18 weeks from the release of a new version of Firefox - the Alpha 1 stage which is 6 weeks in duration.
