Is there an option for increasing the maximum JS memory for a tab?

I was wondering if there way a way to override Firefox's default JS memory limit per tab? Right now, upon reaching about 4-5GB of memory usage, my JS console window reports an our of memory error and dumps my code. I appreciate that this is pretty normal behavior, as 4GB of memory is fairly outlandish for a website. However, for the use case of VR, particularly in physics engine development, it can feel a bit restrictive and even silly when I have 32GB sitting idle - and I could readily double that to 64. However, I know Firefox has a rather extensive about:config section - and I was wondering if anyone knew if one of these variables allowed us to override the internal limits of the browsers memory limitations?

Hi, for the last few weeks, Firefox has been showing ridiculously high disk usage and memory usage - near 100% - growing steadily from the moment I open the program until it stops responding, crashes, screws up my system (mouse cursor hanging etc) and eventually I manage to end process.

Internet Explorer on the same laptop - Windows 8, 8GB of RAM - is fine.

Things I've tried: - Making sure Firefox is up to date. - Turning off Firefox multiprocess - Disabling add-ons - 'Minimize memory usage' in about:memory - Resetting Firefox - Restarting Firefox - The other advice at this page https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram?redirectlocale=en-US&redirectslug=High+memory+usage

What can people advise?

On the same web, Edge is using 153.8 MB, Chrome 0255.8, Firefox 565.9. Why & is this going to be fixed?

These results are in Task Manager when all 3 browsers are on on the same page: https://blog.mozilla.org/internetcitizen/2018/08/13/firefox-privacy-philosophy/?utm_source=… (read more)

Almost a year all versions of Firefox begin to use all available memory (Windows 7, 6 GB) just from start with 5 tabs (Email, Messenger, and some simple websites). Closing tabs never affect memory usage. It seems that Firefox never release memory, only eat more with every next website...

I know the article: https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram And I tried everything from it. The only way to release memory - restart Firefox.

The same problem from another person already marked as closed last year: https://support.mozilla.org/ru/questions/1223605

The best answer: "The more memory is used the better because it means you don't have RAM wasted. Firefox uses RAM to make its processes faster since application data is transferred much faster in RAM." Firefox developers, do you really think so? That eat all available memory for your ONE application is a good strategy?! When I start any other program, Windows begin swapping and swapping, trying to free some space for it...

The screenshot of common memory usage is attached.

This is my rig: www.bit.do/kanishkpc and I use the latest Firefox Beta (always updated)

I have been using Firefox without the kind of memory usage that I am seeing recently. With ~10/15 tabs open, my PC would never be troubled. The RAM usage wouldn't be at 90% but in the past few days (possibly because of a beta update?) I get 50% RAM usage (8GB) with 15 tabs. Yesterday concurrently loaded ~6 YouTube tabs caused a 90% usage from the app and I had to close it.

The RAM usage might seem normal but Firefox actually never uses that much RAM - or didn't earlier at least.

I used MalwareBytes a few days ago to do a malware scan and it found my PC clean. If I did have malware (I had a bit of scare earlier), how would I detect it?
