Major issues with Browser Compatibility

Hi,

I have installed and set up the theme.
But, I am facing major browser compatibility issues – especially on the post page.
I uninstalled the theme, installed again.
Unistalled the demo (using City News) and installed again.
Nothing worked.
NOTE: I have deactivated all major plugins (including cache etc.). But it didnt help.

Here are my issues one by one (only the ones I could detect so far):

1. Post page on Firefox 75.0 (Windows). I have heard similar complaints from IE users and Firefox for Ubuntu. If I do not activate the Mobile/AMP theme, then the problem is there (Android Chrome on Samsung Galaxy S11). It works fine on Windows Edge and Chrome. https://imgur.com/a/3OSkLwo

2. Footer Menu – I am not sure if it supposed to appear there. Ideally, I would have loved to have it like on this page. But, I do not mind the position. However, it gets distorted on mobile and overlaps with other texts ( if I turn the mobile theme off)

Please help me sort these out.

Thanking in anticipation.
