Steps to reproduce:
Calling "new Response();" from a content script in an Addon crashes the tab in Firefox.
This works fine in Chrome and fine in Firefox in context fo the page or devtools. It's only when called from a content script it crashes the tab.
It's not caused by any other code, I commented out all code in my extension so literally just the code "new Response();" existed. My content script is activated on twitter,com and as soon as I navigate to twitter.com the tab crashes instantly.
The tab crashes.
The tab shouldn't crash and I should get a response object returned.
