The ASan reporter addon for Firefox is an internal addon used in conjunction with special ASan (AddressSanitizer) builds of Firefox Nightly. Its main purpose is to scan for ASan crash report files on startup and submit them back to our crash handling infrastructure. Due to the way AddressSanitizer produces its crash information, it would be challenging (if possible at all), to get it working with our regular crash reporter.
The addon is only enabled in builds with the --enable-address-sanitizer-reporter flag set at build time. Currently, we don't produce such builds, but this might change once we decide to hand out Firefox+ASan Nightly builds as part of a special opt-in program.
The URL to the server receiving the crash information.
The client id to send along with the crash information. By default, this is empty. If the user wishes, they can set this pref to e.g. an email address to allow us to contact them.
This is an authorization token that can be used in test setups with a non-public API endpoint that requires authentication. In the final setup, this pref remains empty.
This optional variable can be used to change the default logging level. The reporter addon uses Log.jsm which defines the following values for different levels of logging:
| Level Name | Value |
|---|---|
| ALL | 0 |
| TRACE | 10 |
| DEBUG | 20 |
| CONFIG | 30 |
| INFO | 40 |
| WARN | 50 |
| ERROR | 60 |
| FATAL | 70 |
The default logging level is INFO. All log messages are emitted to the browser console and stdout. Switching the logging level to DEBUG causes additional debug messages related to server requests (XHR) to be emitted.
