Now in Firefox max width of a popup is 680px but in Chromium it is higher - I think that developers of webextensions would be happier without writing Firefox-specific css about width.
Component: Extension Compatibility → WebExtensions: Frontend
Product: Firefox → Toolkit
In `60.0a1 (2018-02-20)` max width of the popup is the same as in Chrome 64: 800px. Can this issue be marked as RESOLVED?
Status: UNCONFIRMED → RESOLVED
