- by Firefox user 13856621, 3 years agoRated 3 out of 5I can no longer enjoy it as it is no longer visible; no icon.
It shows up under add-ons, but not in Firefox.
The speeds are also listed on the add-ons page, but are grayed out and can not be edited.
I checked script-block to see if it was blocking it but was told that the page was privileged and could not be edited.
A similar utility works well on Chrome.
Had to reinstall. Now it seems to work...
