The problem has started again. If I close a tab in Chrome using the X on the tab button, I cannot reopen it from the tab tree by double-clicking. If I save and close, then reopen Chrome, I will be able to restore the tab.

Hi Vladyslav, sorry for the late reply. I tried to use the extension again today and it is working again. I'll let you know if it happens in the future. Thanks for the extension, I think it'll be very useful once I get the hang of it.
