How to vulcanize for Firefox?

[regard...@gmail.com]

I am unable to build an app with vulcanize that will produce something working under Firefox...

The build works fine in Chrome.

I just updates vulcanize (npm install -g vulcanize or num update -g vulcanize).

Maybe I am doing something wrong?

I use it like this: vulcanize -o build.html index.html

Any hints will be welcomed.

I get the following error:

Error: Assertion failed platform.js:16

Do you have a build to play around with?

​This is a really old report, and it appears to be related to Polymer 0.5 or so. Are you really seeing the same stack trace? What version of Polymer are you using?

If you're just having trouble with firefox, chances are you need to include the polyfills (webcomponentsjs/webcomponents-lite.js). Also, make sure that the experimental web components support is turned _off_ in Firefox. 

​Thanks,

Arthur
