Web browser issue

[Edgie70]

Hi all , can someone help me out with why the image on the community site is ok on one web browser but triples the image on a different browser ??? I've circled the image

 

 the triple image is Firefox the single image is Microsoft edge , thanks

Different script interpretation and rendering engines. Edge uses chromium code which the site is more likely optimised for as Firefox is being marginalised by all the chromium based browsers.

Sorry , I'm not 100% sure what you mean about Firefox ? Is it because Firefox isn't chromium based that some sites won't display properly ?

Yes. Firefox is underpinned by code from the 90s browser Netscape that has been tweaked to death to try and keep up with modern web standards.
