I appreciate that this extension has more options than the original Tab Suspender extension. This extension does a good job with the suspending of tabs, but the unsuspending of tabs is not working smoothly on my end. Each time I open a suspended tab and go to un-suspend it, the browser locks up as though it's processing a huge amount of information. Firefox becomes unresponsive for about 15 seconds before I regain control and the tabs eventually reload. A message appears on-screen stating that the tab is slowing down Firefox and asks me if I want to kill the tab.
