Application Basics

  • Name: Tells you the name of the product you are using. In most cases, it should say "Firefox".
  • Version: Tells you which version number of Firefox you are using.
  • User Agent: In addition to your browser and its version number, the User Agent provides other details about your system, such as the operating system and version.
  • Profile Directory: Your profile directory is a folder on your computer where Firefox stores your personal information such as bookmarks, passwords, and user preferences. Clicking on Open Containing FolderShow in Finder will take you to your profile folder, where you can manage your files. For more information see Profiles - Where Firefox stores your bookmarks, passwords and other user data.

These usually include patented formats for video, audio, online games, presentations, and more. Clicking on about:plugins will take you to a page that lists all of your installed plugins, their version numbers, and the type of internet content each plugin is registered to handle. For more information see Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems.
  • Build Configuration: Clicking on about:buildconfig will take you to a page that will help someone understand if you are using a standard version of Firefox or a custom version.


Extensions

Extensions are Firefox add-ons that provide additional functionality to Firefox. They are installed separately, and are usually installed by you. This section lists the name of each extension you have installed, its version, whether it is enabled, and its ID string. It is particularly useful in cases where an extension is the cause of a problem in Firefox. For more information, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.


Modified Preferences

In this section, you will see a list of all settings that are that have been changed from their defaults. This information will help someone know how you have adjusted your installation of Firefox. For instructions on how to reset preferences to default, see Resetting Preferences.


Graphics

Firefox can use your computer's graphics processor to speed up display of some pages with video and animation, which is called hardware acceleration, and to display WebGL content. This section provides information about your computer's graphics device and driver and will tell you whether hardware acceleration and WebGL are enabled or not in Firefox. For help updating your graphics driver, see Upgrade your graphics drivers to use hardware acceleration and WebGL
