Undo Closed Tab Rated 5 out of 5 stars
Never mind previous issue. Add-On was apparently re-set and I didn't think to check until now. Undo Closed Tab features set back to ON, now working like it's supposed to.
LOVE this add-on. It's indispensible. I especially like the feature where a mouseover on a tab selects it. Excellent Add-On. Keep up the great work! :)
