add-on icons disappearing from customize controls evernote web clipper, keeper, zoom scheduler
Evernote web-clipper, Keeper and Zoom scheduler icons have all disappeared but appear to be installed. I have removed and reinstalled the add-ons, and restored my custom controls to default and they are still not appearing. Please help.

Are you using Firefox in Private Browsing mode?
If you are, you need to give add-ons the ability to run in Private Browsing mode. See Extensions in Private Browsing for more information.
Hope this helps.
I am not using private browsing.
Do you see messages in the Browser Console about these extensions if you check this console after starting Firefox ?
