Make sure to also listen to tabs.onReplaced as well, and update the tabStore accordingly.

chrome.tabs.onReplaced.addListener(function(addedTabId, removedTabId) {
    tabStore[addedTabId] = tabStore[removedTabId];
    delete tabStore[removedTabId];

Chrome can change the id of a tab under the hood without warning or signs. As far as I know, the only place that this happens is the Google "instant search" when you type in a search into the address bar. It may be an edge case, but if you don't track this, it could end up being a very insidious problem.
