Thanks Ipstenu

I did just that this morning with a clear head and figured it out fairly quickly.

In case it helps anyone else, I’d changed the default wp-content directory to something else but when I’d defined WP_CONTENT_URL I’d used DOMAIN_CURRENT_SITE but neglected to prepend “https://”

So not really a multisite issue at all.

*facepalm*

Thanks, that shouldn’t be the case as I have other non-wp sites that make far more http requests than these.

How could I monitor whether the server is underpowered?

Total-Cache didn’t solve the issue as I had thought, the problem is intermittent and I leapt to the wrong conclusion.

The files that the http requests hang on vary but so far they all seem to be relatively tiny files. I’ve read nothing so far that would suggest that this should cause a problem.

Example:

Sorry, as I mentioned I can’t provide a link to the sites currently but I will as soon as I am able, if I can’t find a proper solution.

I’ve temporarily fixed the issue by using w3 total cache, but I’m still none the wiser as to why I’m having this issue with Firefox.

It’s not just CSS files that are causing the problem as I thought either.
