What is a plugin?
A plugin is a piece of software that displays internet content that Firefox is not designed to display. These usually include video, audio, online games and presentations that are made in patented formats. Plugins are created and distributed by the companies that make those patented formats. Some common plugins are Adobe Flash, Apple QuickTime, and Microsoft Silverlight.
What is a crash?
A crash happens when a piece of software quits working. Plugins sometimes crash and cause Firefox to crash along with it. On Windows and Linux, Firefox 3.6.4 and above will load some plugins separately from Firefox, allowing Firefox to stay open if the plugin crashes.
What information is sent?
When a crash report is sent to Mozilla, Firefox developers use the information to make future versions of Firefox crash less frequently. Crash reports do not include any personally identifying information. They only include technical information, such as:
- what webpage you were on

- your operating system

- and more technical info.
