I have the middle of the line MBP 2015 with 16 gigs RAM. I notice (as I have with Minis and some iMacs) that various web pages create havoc with revving up the fans with all the crap flash and other ads all over the pages. When I block flash, fan starts going down. Sometimes I kill it from the activity monitor. It doesn't matter if I use Firefox or Safari, same crap with fans revving.
I don't have this quite so bad with playing media files whether they are local or streaming from a service. Damn shame that we spend this much for a laptop that ends up crying (fans revving) when we go to certain pages on websites chalked full of BS ads.
Look here, then try AdGuard it will stop the adverts in their tracks...
