The issue you are running into has to do with web standards. Safari tends to be a little ahead of the game in adapting internatinoal web standards, where Chromium-based browsers (Chrome, Firefox, etc.) do not. Web developers often "build for Chrome" in that they add Chrome-specific web code to ensure the site works, while not meeting web standards. Unfortuantly, the more people who ignore the standards and code to work with Chrome, the more likely websites will continue to "break." Here's a good debate and expliantion of the details: https://www.quora.com/Why-don-t-certain-websites-work-on-Safari-but-work-on-Chrome-just-fine-and-never-vice-versa-What-are-they-trying-to-cover-up?share=1
