Firefox Restartless Addon：启用/禁用上记录的错误

Question

I have been testing and when a Bootstrapped/Restartless Addon is enabled or disabled, a number of errors are logged relating to other addons.

Duplicate resource declaration for 'specialpowers' ignored. chrome.manifest:32
Duplicate resource declaration for 'gre-resources' ignored. chrome.manifest:33
Duplicate resource declaration for 'services-sync' ignored. components.manifest:163
Duplicate resource declaration for 'services-common' ignored. components.manifest:165

On enabling the restartless addon:

Could not read chrome manifest 'file:///C:/Program%20Files%20(x86)/Mozilla%20Firefox/browser/extensions/%7B972ce4c6-7e08-4474-a285-3208198ce6fd%7D/chrome.manifest'.

I have tried different Restartless addon and all log similar errors (from other sources) on enable/disable. The errors do not appear to affect the operation of Firefox or the addons.

What are these?

What are these?

Noise. Really, disregard all of those.

• Those "Duplicate Resource" warnings are due to the way Firefox (re-)loads manifests.
• "Could not read chrome manifest" in the installation directory is because the platform supports having a manifest in the installation directory but Firefox doesn't use this capability (anymore).
• The Service.Metrics.Provider ones are related to the performance metrics Firefox collects and may send to mozilla if you opted-in. That thing doesn't really know how to deal with certain add-on types, and hence the warnings.
• The 972ce4c6-7e08-4474-a285-3208198ce6fd manifest warning is the default theme. I didn't even know it is still around. Probably a left-over from installing Firefox back when and upgrading afterwards.
• And then there is something trying to load a DownThemAll! 3.0 file, which isn't present.
