Hi Alan, Plug-In is a complete program and add-on is not a program. For example Flash is an plug-in which is a complete program. Flash player is required to play a video which is made by Adobe. Also Java is a plug-in made by Sun Microsystem which is used to run programs based on Java. Plug-in is not bounded for browsers only. Flash can be installed in computers to play flash files. Similarly Java can be installed to run Java files.
On the other hand Add-On is not a complete program. It is used to add a particular functionality to a browser. Many browsers come with add-on features. Firefox, Chrome, Internet Explorer, Safari have add-on facility. In Chrome and Safari an add-on is known as extension. There is no difference between add-on and extension. Both are the same terms used differently in different browsers. Why do you think Mail could be causing Safari to crash/quit? When Safari crashes have you viewed the Diagnostic Report in Console to try to find a clue as to why it crashed? After Safari crashes a diagnostic report log with the name followed by ".crash" is saved in ~/Library/Logs/DiagnosticReports folder. The easiest way to view these reports is to open Applications > Utilities > Console application, and then click the 'Show Log list' button in the toolbar. The diagnostic reports are chronologically listed in the Diagnostic and Usage Information section. Most of what you see won't mean much to you, but you can find which files were being used by Safari at the time. One of the reported files could be the source of the problem due to corruption.
