Re : Firefox

Hi @sourds29!

I checked your page in Firefox, and the slider loads fine for me, so it is possible that it is probably related to your Firefox. I can also see cache on your page, which often causes issues too, so I suggest following these steps:
1. Disable all Cache/Optimization plugins. I can see WP Rocket, and BS Booster in the code too.
2. Make sure to update and have the latest version of Firefox
3. Check your page in incognito mode (by default extensions don’t work in incognito mode, so you can find out if one is causing the issue or not)
