After Bug 94416 - Web Inspector: load scripts panel lazily the Settings fails to open unless the user happens to open the Sources panel first. SettingScreen.js uses WebInspector.settings.searchInContentScripts p.appendChild(this._createCheckboxSetting(WebInspector.UIString("Search in content scripts"), WebInspector.settings.searchInContentScripts)); But the value is not define until ScriptsPanel.js imports ScriptsSearchScope.js Source/WebCore/inspector/front-end/ScriptsPanel.js:importScript("ScriptsSearchScope.js"); which creates the setting: WebInspector.settings.searchInContentScripts = WebInspector.settings.createSetting("searchInContentScripts", false);
I'l fix it right away. Now that it squeezed into the Canary, the workaround is to open Sources tab first. Then settings will open.
