I’m developing a firefox add-on and would like to embed a redirection page into my extension. This redirection page needs to be whitelisted. Is there a way to know what the moz-extension:// will be at development time? The GUID seems to change for each install of the add-on. When installing from the developer add-on page I get one GUID, but after I have published and signed the add-on I get another GUID. Will this GUID change from machine to machine and user to user?
developer add-on install
signed add-on install
For Google Chrome add-ons once an add-on has been published to the store that GUID remains constant for the each install and updates to the extension.
