Solution 1:
To use, in Firefox, Custom Elements v1 with HTML Imports:
- Do not activate Firefox flags as the implementation is outdated.
- Install webcomponentsjs (with bower for example), and include in your main file only
htmlimports.min.jsfile. - Install custom-elements (from your link) and include in your main file
custom-elements.min.js.
You main page should look like this:
<head><scriptsrc="htmlimports.min.js"></script><scriptsrc="custom-elements.min.js"></script><linkrel="import"href="your-components.html"></head><body><your-component></your-component>NB: for step 3, you can also use document-register-element.
You cannot use Custom Elements v1 class syntax with Internet Explorer directly because class is not implemented. You'll need first to transform the source code with a transpiler like Babel.
Alternately, use a modern version (Edge), or use the prototype syntax.
