Nice add-on Rated 5 out of 5 stars
Very useful add-on, thanks. The only minor is with Tree Style Tab. This add-on has special handling for browser-wise "New tab" command (for example setting for opening it as a child of the selected tab). But Search by Image always opens new tab as the last one so it looks like the invoking of this command bypasses TST add-on. But I'm not sure whether API allows such flexibility. Anyway, thanks again.
