My addon has been in the repo for several years and uses an XUL overlay to build a toolbar. I am trying to rebuild this addon to use the addons SDK so it will be compatible with future Firefoxes.
So I’ve installed my original addon into Firefox Developer Edition with multi-process enabled. I am using the Extension Auto-Installer and jpm to post the addon to Firefox.
However, I keep getting this error:
[CustomizableUI] Widget action-button--myAddonID-misspelutton not found, unable to remove from inner-toolbar-myAddonID-the-title-of-my-addon1 CustomizableUI.jsm:171
I have a thread for this over on Stack Overflow. Please view my thread there for the details.
How can I prevent/solve this problem? I am afraid for this to happen to folks who upgrade my addon once I’ve rebuilt it.
