I use Google Chrome and have very slow internet. It's metered, so when I run out of my allotted data, they cut me back to roughly dial-up speeds. I'm a Premium Member now, but before I was, I didn't have any issues loading the forum even when my data was out. 
Maybe try Chrome? Or test out the Premium Membership for a few months? I can highly recommend it.
 I did it for a lot of reasons, but using less data and not being so cluttered on mobile were two of them.
