Hey there, I have developed an add-on which replaces my start page. When loaded using the “load temporary add-on” functionality from the about:debugging page it works properly, and when I go to a new tab I get the correct new tab I designed. Hooray!
However, I cannot figure out how I am meant to package this file in order to load it manually into my Firefox permanently. I do not plan on hosting it as it is really only useful to me, and I see that I can load an add-on from a file, but I cannot figure out how to load it. I tried zipping it but that did not work.
If anyone has any insight I would really appreciate it!
If you want to permanently install your extension, you’ll still need to upload it to addons.mozilla.org for signing. Select the self-distribution option at the beginning of the submission process; once you finish, you’ll get a signed .xpi file to permanently install into Firefox.
