JavaScript error: chrome://global/content/aboutPerformance.js, line 1114: TypeError: row.nextSibling is null; can't access its "firstChild" property This happens when attempting to hide a subtree at the bottom of the list. So either when collapsing the "Recently closed tabs" section (which is always at the bottom), or when closing a tab that's the last row in the table. This is just noise in the console, can be fixed with a simple null check.
