Most of the time I get: Error: oldLocation is null Source File: file:///home/doug/firefox/components/nsExtensionManager.js Line: 7867 But sometimes it's installLocation reported as null on line 7971. No consistency between them. Reproducible: Always Steps to Reproduce: 1. Install add-on 2. Restart Firefox 3. Load error console Actual Results: Error: oldLocation is null Source File: file:///home/doug/firefox/components/nsExtensionManager.js Line: 7867 or similar error with no add-ons loaded Expected Results: Add-ons should load and no error should be reported. Have tried using several different Ubuntu themes (including Human) and all reproduce this error. Using the standard package install location.
