fine but... Rated 3 out of 5 stars
After a some point of 15.x branch (IIRC) the red highlighting in DOM-Eraser mode didn't work -- it still shows a pointed elements tooltip but didn't draw a red frame around it. This found on the two different machines. And the same still up to the current 16-beta6.
An original SB works fine but has a bug with a multilevel capture filters while SB+ allows extremely fine tuning of them.
Now I have both SB+ and SB installed and swithing between them as needed. And this is very annoying.
