How do I move an addon button that is grey-out in the Customize Display and stuck in the legacy status bar to another location. Normal customize/drag/drop does not work for this addon (Gmail Manager-community 0.7)? I use both CTR and Status4Evar, but still cannot move it.
This addon works normally except randomly when I click on its button, I get the handgrab icon and the only way to restore normally functionality is to open/close the Customize panel. This issue has occurred in all FF 39.x versions and possibly ever since the current Customize UI has been in effect.
It’s likely the add-on doesn’t use the “new” toolbar and button APIs. The add-on would need to be adapted to use those APIs in order to continue working correctly.
