FF 63 is deployed in our organisation, and we use the autoconfig logic to configure preferences. Since FF 63 autoconfig.js which calls "mozilla.cfg" has stopped processing code following on from the section under the comment "// Disable crash reporter"

The segment of code that appears to cause the issue is as follows: "Components.classes["@mozilla.org/toolkit/crash-reporter;1"].getService(Components.interfaces.nsICrashReporter).submitReports = false;" If I comment it out then the code below this is processed successfully. You'll also see in the text of "mozilla.cfg" that I commented out the section altogether and moved it to the section starting... "// ************ Crash reporter code moved as it..." i.e I moved the code to disable Crash Reporter to the end of the file so it executed last. I'm pretty sure the code deosn't execute as it just appears to cause Firefox to 'stall' until it starts.

Last bit of evidence, In the Browser Console one of the messages is as follows: "ReferenceError: Components is not defined[Learn More] firefox.cfg:57:1"

Any ideas on how to fix this please? our organisation policy is not to submit crash reports to stop data leakage, hence why we want crash reporter disabled.

Thanks in advance,

Pete

Firefox 63 runs autoconfig.cfg in a sandbox and you can no longer run privileged JavaScript code. "Autoconfig is sandboxed by default":

This is still possible in ESR versions.

For current Firefox releases there is a pref that you can set to false in the autoconfig.js file that specifies to use autoconfig.cfg.

  • pref("general.config.sandbox_enabled", false);
  • Bug 1479857 - Add a preference (default off) for autoconfig sanboxing for first release [general.config.sandbox_enabled]

Thanks for the info @cor-el.

I understand what to. Do with the autoconfig.js file now, i.e. add the line “ pref(“general.config.sandbox_enabled”, false); “ to it.

To disable the Firebox Crash Report I need to take which action?

This means I don’t have to worry about what happens with the sand boxing of autoconfig in future as I’ll already be using the desired default configuration.
