5 instances of FF 57. (64bit) open and using huge memory

[Accredo]

Whenever I log into a news site FF 57.0 (64 bit) slows down to a crawl. I noticed in windows task manager there are 5 FF running.
However, I only open FF once. And as you can see from the screenshot below, FF is using a huge amount of ram.

Well 64 bit Firefox is now a multi process browser. My guess is you have some sort of extension running? Have you tried Firefox Safe mode?
I have six Firefox Processes but only 380mb of ram used so something else is causing your problem

Hello Malliz and thanks for the reply

I'm not sure which extension would cause this. I only have a PW manager/ublock/Gesturfy/group speed dial/Kaspersky and google translate running.

I'll give safe mode a try and see what happens.

Well I am using Ublock so it may be one of the others

URL?
Does the same issue occur if you don't log in?

You're not using CPU.

How much RAM do you have?
It might, probably is, just be the pages you're visiting.
x64 & e10s, so what, you've got at least 4 GB.
And you're only using ~2 GB.
I wouldn't expect memory usage to be an issue.
So, I'm back to the pages.

Using an ad blocker?

What is that "chromium" thing?

Same high memory issue here. Look at the RAM usage on my computer with only ONE instance of the new Firefox running, it's almost 3GB of RAM utilized!! WTF happened?? I thought this new browser was supposed to be fast?? Instead, I am now crawling along, often waiting for a minute or so to refresh a page or get a new page. This is terrible...............

I think it will be the same for everybody. Multiprocess doesn't only mean you need extensions to see more than one instance. I have several extensions installed, and my install is showing seven. Even if you have a fresh install with a new profile you will see more than one.
