Uploading symbols to Mozilla's symbol server

As a third-party releasing your own builds of Firefox or B2G, you should consider uploading debug symbols from the builds to Mozilla's symbol server. If you have not disabled crash reporting in your builds, crash reports will be submitted to Mozilla's crash reporting server. Without the debug symbols that match your build the crash reports will not contain actionable information.

Symbols can be uploaded either via a web browser or a web API.

Building a Symbol Package

To upload symbols, you need to build a symbol package. This is a .tar.bz2 file which contains the symbol files in a specific directory structure.

If you are building Firefox,or a similar application using the Mozilla build system, you can build the symbol package using a make target:

./mach buildsymbols

This will create a symbol package in dist/ named something like firefox-77.0a1.en-US.linux-x86_64.crashreporter-symbols.zip .

Uploading symbols

Symbols are uploaded via your account on crash-stats.mozilla.org. Visit https://crash-stats.mozilla.com/symbols/ and log in. Then request upload permission by filing a bug in the Socorro component using this template.

After symbol upload is turned on, you can upload the symbol archive directly using the web form at https://crash-stats.mozilla.com/symbols/upload/web/. It is also possible to upload via automated scripts: see the symbol upload API docs for more details.
