I get these from bug 153677 comment 6 steps: {{ Enable QuickLaunch, Close all windows, (let Mozilla QL-icon restart itself), Open Navigator from the QL-icon. }} Result: {{ Error: updateHomeButtonTooltip is not defined Source File: chrome://navigator/content/navigator.js Line: 135 Error: updateHomeButtonTooltip is not defined Source File: chrome://navigator/content/navigator.js Line: 135 Error: prefName.substr is not a function Source File: chrome://navigator/content/navigator.js Line: 95 Error: prefName.substr is not a function Source File: chrome://navigator/content/navigator.js Line: 95 Error: prefName.substr is not a function Source File: chrome://navigator/content/navigator.js Line: 95 Error: prefName.substr is not a function Source File: chrome://navigator/content/navigator.js Line: 95 Error: getBrowser is not defined Source File: chrome://navigator/content/navigator.js Line: 167 }} +(K) regression: v1.8x, but not v1.7.x.

I think these all depend on the nsIControllers.removeController exception in Shutdown on line 751 of navigator.js - the problem is that the subsequent code is necessary to prevent the errors listed here. jst, is it actually necessary to remove controllers on shutdown, or does the window clean them up?

The current trunk doesn't have quick launch. It doesn't support Win98 either. Serge, Neil: WONTFIX?
