Hi, thanks for the feedback. first time I see this. I have tested in the latest version of firefox and chrome and the website loads well. Which version of firefox are you using? If you update firefox, does the error continue? If you press Ctrl+Shift+K (or go to menu > Web Developer > Web console) do you see any errors/warnings?

Seems to be a Ubuntu specific problem, will take a look this weekend.

this conversation motivated me to upgrade my ubuntu from 17.10 to 18.4 and this also incremented firefox by one version but the issue is the same. A deeper look at my plugins was neither enlightening. Also a new private browsing window didn't change anything. Clearing cache didn't help.

Was not able to reproduce... Still, I think I know something that might solve it, will send you a link for you to test to tell me if it solves later.
