Firefox Responsive Design View issue

Hi,

When i switch to Firefox Responsive Design View i have some visual issues.
for eg. the list borders getting hidden but in chrome everything is fine , is there any workaround to make it right ? (firefox version is: 65)
i am developing a cordova app and in first phase of development i test the view and login in browser, is there any alternative much more closer to android and ios webview !?

Regards.

Yes, it is desktop Chrome or macOs Safari. Develop it there where everything is ok

have you noticed these visual issues in firefox Responsive Design View your self ?!

Yes, and it is the issues with FireFox itself
