Hmm, that's weird, for me firefox is just as slow as normal chrome.

The other trick I use is to disable image on this website. I notice improvements, but the downside would be the fact that all the images would be blocked. 

Yeah, I switched to Chromium completely now. It's basically Chrome Lite. No problem whatsoever now. 

You can also try to use other browsers, such as Edge instead of Google..

It still won't work unless you changed the url from https to http

I tried it on different browsers before.

Anyway, I switched to Chromium and it works amazingly. Page load in split second now. I highly recommend it instead.

I checked the memory usage per tabs on Chrome, it stands around 400mb per tab. On Chromium, it only took them around 150mb per tab. So that might explained it a bit.
