NS_ERROR_FAILURE in Firefox

[arviesan24]

I keep getting this error in Firefox which is not present in Chrome:

This is its initial layout when the page loads:

and will become like this when you try to drag downwards the toolbar from the top:

I'm using Firefox 66.0.5 in Ubuntu.

Could you share your Summernote settings? It looks like this problem is up to summernote's isFontInstalled function. It uses <canvas> to test whether a given font exists or not.

This is the only changes I made on its settings. I'm using django-summernote==0.8.11.4

SUMMERNOTE_THEME = 'bs4'

SUMMERNOTE_CONFIG = {
    'width': '100%',
    'height': '300',
}

Thanks. I will find out after installing Linux on my laptop.
