I was asked to add a Facebook feed to one of the sites I created. Two strange things are happening:

1. While it looks good to me in all browsers, the customer says in Firefox it isn't centered and is instead on the left side. They have tried ctrl-refresh and still the same.

2. It shows the 5 most recent posts and then repeats.

Ugh. Forgot the link https://www.westlundexcavating.com/

It seem that at least the first problem is not related to Firefox, but to the matter of viewports. At less than 1200px browser window width is where the problem starts in all browsers.

Several breakpoints are set, and it's worth reviewing the pages at all widths.

Regarding the second problem, I wonder whether this is the problem addressed in https://www.simpleinbound.com/facebook- … ore-issue/ .

You have a break point hitting at 768 kicking it to the left.

The facebook thing seems to be an issue being talked about here.

I opened in Firefox and Facebook is centered, everything is fine

You're facing two issues with adding a Facebook feed to a website. Firstly, the feed appears centered in most browsers but aligns to the left in Firefox for your customer. Check and adjust the CSS styles for the feed container to ensure consistent centering across browsers. Secondly, the feed displays the 5 most recent posts but then repeats them. Review the configuration of the Facebook feed plugin or API to ensure it's fetching and displaying unique posts without duplication.
