My site isn’t showing up on Firefox at all. It shows up in Chrome and Safari, but on Firefox it either loads just the Hero partially or it doesn’t load at all and hangs. It’s not the cache, I’ve cleared it, and have tested it from different ip’s/computers.
Hey @Nathalie_Rosengarten welcome to the community! 
It’s going to be nearly impossible to troubleshoot the issue you’re running into, so please include the live site link so we can take a closer look.
That said, it sounds like it could be an issue with your browser addons — have you tried opening the site in an incognito Firefox window (with all addons disabled)?
