I would like to use a simple add-on to override my new-tab and home pages with the contents of my own HTML file.
Currently what I have done is:
- Installed Firefox Developer Edition. It seems people have implied you can only install unsigned add-ons using certain builds of Firefox, this being one of them. This seems strange since
xpinstall.signatures.required
can be disabled in every build? - Ran
web-ext build
inside my add-on’s directory which produced a zip file of my add-on. - Attempted to use the
Install Add-on From File...
feature on theabout:addons
page. However, I receive an error saying the following:
This seems strange considering the add-on hasn’t been downloaded from a site, it was created on this machine.
