Usually the thing about the webpage not working is just codeword for "we have not tested it and we won't". If you really need to access it, there are some extensions that can change your user agent so the page thinks you are in chromium.

This is the one I use.

I use an user agent switcher in those cases. Most of the time it works and I dont have to change the browser.

This is not fully true. Recently I had problems with keyboard press event propagation working differently on button elements and CSS scroll snapping behaving differently when new items are appended in the scroll container. Both are not really obscure.
