Rated 5 out of 5 stars

Today I had to give up (due to laggy firefox 56 plus other issues) and upgrade my firefox to 57 where this extension is not supported. Still hoping this will be ported to new versions of firefox... i'm still not giving up using firefox eventhough chrome has really outrun it.

This review is for a previous version of the add-on (0.8.1.13).
