563969 - JavaScript component does not have a method named: "observe" when calling method: [nsIObserver::observe] (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: General, defect)

Description

[Martijn Wargers (dead)]

I'm seeing this error in the js console when clicking on the "Clear Private Data" button in the options:
[Exception... "'JavaScript component does not have a method named: "observe"' when calling method: [nsIObserver::observe]"  nsresult: "0x80570030 (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)"  location: "JS frame :: chrome://browser/content/sanitize.js :: anonymous :: line 171"  data: no]

It seems to be happening when you have an about: url (about:firefox, etc) opened.

(to be able to see js errors, make sure you have the javascript.options.showInConsole pref set to true and the browser.console.showInPanel set to true in about:config)

I'm seeing this on trunk and branch as on windows and Maemo.
