Mozilla FireFox is the second most popular browser after Internet Explorer.

Why Does FireFox Crash?

But that doesn’t happen too often nowadays (it used to, when FireFox was still a new thing).

Update Flash

Another common thing that causes FireFox crashes is outdated Flash. Because FireFox is updated very frequently by Mozilla, it’s important to keep all of your browser component up-to-date.
