Smells like bug #247748.

It looks like the web process is pretty busy, but I don't see anything in particular that looks suspicious.

Secondarily: I notice the network process is spending an inordinate amount of time calling gnutls_x509_trust_list_add_system_trust(), which is supposed to be a one-time operation. That's weird. Well, it's a one-time operation per GTlsDatabase, but each GTlsConnection should use the default GTlsDatabase. I see p11-kit is also working pretty hard. So that's surprising and certainly not good, but it should also be a one-time problem that happens only when you first start the browser.
