Flagfox

I'm using Version 3.2.0 of flagfox. This version is the last, that's running. All updates failed. After downloading and restarting firefox, the icon does't appear. In the Addon-Settings I can read please restart firefox. After downloading version 3.2. 1 firefox changed the theme form walnut to default, but the flagfox does't work. The same with version 3.2.5.
What can I do?

Weird. I don't see how Flagfox could be at fault here. Nothing in Flagfox should be able to alter your theme. Did you also update something else at the same time? What version of Firefox are you running, and on what operating system?

Please give steps 4 and 5 here a try.

Thank you for your hints. In a new profile the Walnut-Theme and the newest flagfox version are working together properly.

I don't suppose you figured out what caused this in your old profile?
