Seems to work_can't remove toolbar icon Rated 4 out of 5 stars
Haven't used it extensively - esp. in Fx 23. Basic sorting seems to work.
Don't use some of more advanced features - yet.
DEFINITELY need to fix so can remove the icon from addon bar. Can drag it away to the "icon stash" box, during customize, but next Fx restart, icon is back in addon bar.
Descriptions of settings in the options UI are helpful.
In the version 2.1, the icon from the addon bar is completely removed.
