Plot display but the content is empty when the plot is saved as HTML and it is opened in Mozilla Firefox

[erikfilias]

Dear,

I tried to open Mozilla Firefox, a plot that is saved as HTML. The plot is displayed but the content is empty as it is shown in the next image: I am using Altair 4.1.0 in Python 3.9.5

Any suggestion will be appreciated. Thanks in advance.

Thanks for the report - it's hard to help without more information.

1. Can you include the full code snippet used to create and save the chart? (preferably a minimal reproducible example, which may involve creating a similar chart using a different, simpler dataset)
2. In firefox, can you check the Browser console for any errors that are displayed?

Thanks for the comment.

1. My chart is a time series with an hourly resolution that is opened without any issues in Google Chrome and Microsoft Edge. Sorry, my example is not a minimal reproducible one. It can download here.
2. In the console appears this error: How could I solve it? Thanks in advance.

3rd party zip downloads are suspicious, and I'm not willing to click on that link. Please edit the original question and paste your minimal reproducible example code. Thanks!
