Nice extension but it is using near on 500MB disk space so it needs to go. :(

Drag'n'drop doesn't work. I read your developer response to ofaurax and I've tried everything, including pulling out my last few hairs. If I cannot move tabs about then what is the point of this app?

Drag and drop to re-arrange tabs doesn't work. I can drag a tab, but dropping makes nothing
