In the WebExtension API, what is the proper way to reset the new tab page to a custom one?

Add-ons Development
#1

In chrome, this could be handled in the manifest.
I’m not sure of the proper approach in Firefox.

#2

There are APIs that can do that in Firefox, but they are not (yet) available for WebExtensions.

#3

I know. I’m asking this because I’m trying to port application from Add-on to WebExtension but it seems like many of the needed functions are MIA.
You could technically detect a new tab creation using the TABS API and if the URL is unset or is set to the default new tab URL to redirect it elsewhere.

That sounds like a really bad idea :smiley:

You could embed your WebExtension in a SDK add-on, port everything exept for the actual new tab overwrite into the WebExtension and use messaging to call the overwrite in the SDK code.

A WebExtension API for this will most definitely come in the future, and this is a good way to start porting now.
