Why is Firefox 70.0 is ignoring my HOSTS file while other browsers work properly?

I'm using an extensive HOSTS file to block content, etc., from websites, which is a pretty common use of HOSTS. However, Firefox 70.0 is ignoring the HOSTS file and loads sites that are explicitly named as 0.0.0.0 addresses. Other browsers, such as Chromium, work as expected and return a "not found" message. Is this a bug in Firefox or is there some setting, such as under about:config, that needs to be set properly? Thanks for any help/suggestions.

Am I missing the solution? I have recently started having this problem with Firefox 74.0 (64-bit) where I can't access local web sites whose entries are listed in my hosts file. I *can* reach them using Chrome but I don't want to have to switch my default browser if there's a solution available.
