Firefox for Android Support Forum

How can I resolve the issue of my website not displaying properly on Mozilla Firefox browser, specifically with regards to the layout and formatting? Are there any specific CSS or HTML codes that need to be modified to ensure compatibility with Firefox, and are there any known compatibility issues between Firefox and certain web development frameworks or libraries that I should be aware of?

Firefox Browser on Android, 106.1.0.

Datalist options do not show at all.

On Windows, although there is no downward arrow like in other browsers, the options do come up when I click into the input field.

On Android, nothing.

When I was using Chrome I would get this message on some web pages they wouldn't open they would say I needed to download a web browser set it up and install it all right now that I've downloaded Firefox I'm still getting the same message sometimes what do I do to fix that message what am I doing wrong?

For sometime now I have been unable to access my Bell email on Firefox except if I use private browsing and then it allows me to get to my login and by default allows me to enter my login and password. But if I don't use privacy browsing mode, I cannot get to my email. This is on my android Samsung phone btw. Bell tells me it's a browser issue and that I'm to contact Firefox or switch to Chrome or Edge, but I'd rather do it through Firefox. Can anyone assist as to how I can correct this issue?
