I hope the devs fix this in the next update because this is very annoying,” someone else adds.Īt this point, the only thing you can do is just let Mozilla know about this issue, and instructions to send feedback on RAM are available in the linked reddit thread. As long as I've been using Firefox it's never hogged this much memory before. “I've been having the same issue I thought I was going insane, I thought my browser was infected with malware or something. Currently waiting for devs to address the issue,” one user on reddit explains. Multiple users including myself reported this issue. I have a PC with 4GB RAM and the impact is visible. I've even started to face sluggish behaviour with 2 or 3 tabs where Chrome keeps the sanity. “You are not the only one affected by this. While this is something that nobody would have imagined a couple of years ago, users complain that Firefox can sometimes even crash systems with a limited amount of RAM due to this increased resource usage. The new Firefox has become quite a memory hog, users now complain, with a thread on reddit indicating that Mozilla’s browser eats up much more RAM than Google Chrome. There's no painful tradeoff to make here.Mozilla Firefox has long been considered the main alternative to Google Chrome, with many praising its low resource usage, but it looks like everything has changed in the latest update for the browser. If you're thinking, "I want that RAM free now so I can use it later", forget it. If you had 1GB free for the last hour, you gained no benefit whatsoever from that 1GB in that past hour. Modern operating systems go out of their way to have as little free RAM as possible. They certainly don't do work that they'll probably just have to undo later. Smart systems only expend effort when there's some expected benefit. Freeing and allocating memory takes effort. At a minimum, it allows Firefox to use up to 2GB of memory without having to allocate any more memory, which is a win. It's perfectly reasonable if the alternative is to have some of that RAM be wasted and holding no data whatsoever.

The fact is that firefox sometimes uses upto 2Gb of memory which does not seem reasonable for the number and content of tabs being open. It is not returning to the initial level because it would take effort to do so and there would be no benefit to expending that effort.

So, simply put, Firefox is using more memory because the alternative would be to waste that memory. A system with 8GB of RAM can't use 4GB today in order to use 12GB tomorrow. Your only choices are to use it or waste it.
