Rated 4 out of 5 stars

Don't work on Firefox 40.* :( ... Please, fix it
***My apologies for the previous 1 star due to an error ... I corrected my review. It is a very good extension for this I made my request. But now, the problem with FF 40. * is solved and I hope the same is true for the misunderstanding with the developer.

This review is for a previous version of the add-on (3.31.1-signed). 

Update: Thanks & glad to hear it's working now.
