Firefox memory leak?

I've been noticing that Firefox becomes very laggy and unresponsive on my high-end desktop, and Windows task manager reveals that a FF thread often takes 3-5 GB of memory that increases over time. This does not show up in FF's task manager.

I haven't been able to identify the cause of this, and it's weird that 3-5 GB of memory will slow things down that much when I still have ~8 GB unused memory.

This is on a pretty fresh Win10 install.

I have tried to attach my about:memory report below, but in case it doesn't go through, I also hosted it on GDrive. https://drive.google.com/open?id=1qyGQShX78PculdEmacm8hO9jqn4E1GWh

Can anyone please help me resolve this issue?

High RAM usage

Why Firefox using all of my memory. My PC 8GB RAM. Firefox uses 6GB RAM only for 1 tab? I only read manga at http://www.mangahere.cc/ if the ram is almost full, I have to restart Firefox. Why is RAM management in Firefox so bad? I'm tired of this, please fix it. If you don't believe it, you can test it by reading a random manga.

Why do I restart firefox when ram starts full. Because, if I don't restart, then the other programs that run will lag or hang. In other words, Firefox makes other programs to move to a virtual memory (page file).

I hope I can limit firefox to use RAM (for example 3GB).

Over the past month I have been noticing that Firefox just absolutely runs wild with memory allocation. If you look at these screenshots you can see it hogging over 17GB of ram...

Over the weeks I have tried a few things, one of them was a clean reinstall with no existing profile folder. Is there a way for me to limit the maximum amount of usable ram or find out what exactly is doing this?

It seems that over the last two months firefox has been causing my hd to run at 100% for long periods. I have followed advice on the internet and disabled a number of searches within the pc settings that originally helped and also updated the power plan to high performance which initially helped.

Every hour or so my pc goes into a phase of running its hd at 100% to the point that I cannot even type in the search bar. Indeed it has taken over 30 minutes to finally get to the position of being able to type this query.

the pc is not that old and has light usage and all memory appears to be working fine. If this does not fix then I will have to go over to Chrome.

Firefox used all RAM and SWAP taking mins to load freezing system, then dropped to less than a gig.

  1. 171-Ubuntu SMP Tue Mar 26 12:43:40 UTC 2019

Opened Firefox one day, and soft-locked my system for several minutes. Killed it... repeated this process over a few days. Today finally opened it and just let it run to see what would happen. Ate all available ram. Then the swap. When it finally maxed both everything emptied out. System is now using less than a gig of ram and about half a gig of swap for everything.

Any idea what just happened and how I prevent it from happening again? I will also note - I have a lot of tabs.

Firefox Quantum Spikes CPU Usage When Opening A New Tab

I'm using FFQ on my MacBook Pro - OS X machine running High Sierra, and when I open a webpage in a new tab (background or not), my CPU usage spikes through the roof and the entire computers slows way down. I watched the activity monitor to see what was going and most of the processes are idling kind of high (about 22%), but there's one process that is definitely the one causing issues. On a new tab being opened, the "Firefox Developer EditionCP Web Content" process spikes as high as 115%.

Is there a way to fix this, or at least make it not-as-bad? I love FFQ on my Windows machine, but it's making my Mac nearly unusable.

Specs: - Machine: 13" MacBook Pro 2013 - FFQ Version: 63.0b4
