HIgh memory usage seems to continually increase!
I realise that Firefox uses up a lot of Memory (particularly as it tries to run each Tab separately). However, my Firefox seems to keep increasing its usage!
I can start with a number of Tabs open & (after refreshing each Tab - to ensure it is "lice" & "active") I will get (according to Windows Task Manager) about 1,300MB in use.
Without opening up any more Tabs & without trying to run any Web-Based Videos, over a period of a few hours it will increase & increase & increase - perhaps getting up to 4,000MB!
I've cross checked with "about:performance" (to open FF's own Task Manager), to show the individual Tab usage, & that NEVER totals up to anywhere near the figures shown by the Windows Task Manager!!
Obviously, my FF is fully up to date!
Any comments!

Start Firefox in Safe Mode {web link}
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

MemTest LAST UPDATED : 12/04/2020
Could you please run a tool from http://memtest.org/
in order to check the integrity of your RAM?
You will need a thumb or disk drive to install it on.
Do you let Windows handle the page file or did you set a fixed size ?
If you use a fixed size for the page file then try the former and let Windows handle the page file.
Hi, @FredMcD,
Thanks for your response!
Have just re-started in Safe-Mode & the total memory used (as reported by Windows Task Manager) is still approx 1,300MB & the FireFox Task Manager (about:performance) is still showing considerably less (approx under 500MB).
However, my main problem is the fact that (over a number of hours) is seems to gradually use more & more memory!
Have previously read most of those Links & they also seems to be based on basic High-Memory usage (i.e. High ALL of the time), NONE of them mention anything about the gradual & increasing Memory Usage (in my case, increasing by a factor of 3!)!
Windows Page File is set to "Default" (which I assume is that Windows handles it) & never had cause to change it!
It is late evening in the UK, I'll leave it running overnight & see if there is any dramatic change!
Hi,
After running FireFox overnight (& carrying out a Refresh on all open Tabs) the Total Memory used by FireFox (according to Windows Task Manager) is now up to 1.600MB - a slight increase from just below 1,300MB - whilst FireFox's own Task Manager is still showing a total of less than 500MB!
I called for more help.
Hi, @FredMcD,

I assume that you were unsuccessful in getting more help?
Thank you, anyway, for your efforts - they are really appreciated!
Best wishes, John-B
I put out the call. That's all I can do.
I too have this problem for a while now. The memory that all the tabs and add-ons use is not more than 1GB. But the memory that Firefox uses as reported by windows 10 can even reach 7GB. I have version 87.0 running on Windows 10 Pro OS build 19041.867.
You guys don't even have a problem, my Firefox is currently using 15 GIGS OF RAM!! And i restarted it just a few hours ago! This is so ridiculous.... The FF app alone is using almost 5 GIGS, and over 100% of my CPU!!!
With every new update I hold out hope it will finally run without sucking up so much RAM & CPU Usage....but not happening.
Hi, @StevenCee,
Sorry to hear that you have the same Issue (albeit, a much more difficult situation)!
I note that @FredMcD did a very good job at attempting to assist, but eventually having to escalate it - what I don't understand is why the Developers do NOT seem to be trying to address this Issue!
Regards, John-B

I manage the memory Firefox uses by closing certain tabs if I am no longer using them. Sites such as Facebook use a lot of memory if you leave their pages open. It is easy enough to restore a tab provided you don't close more than the number specified in about:config. I also, for example, close tabs containing articles or forum threads which I have read. On some sites (such as this) I don't open separate tabs for individual threads. I notice use of ram increasing if I leave my computer unattended for an hour or so. In that case I use a button on about:memory to minimise memory usage. It has reduced memory in use by as much as 600 MiB. Firefox isn't the only application I have open and it isn't necessarily the application using the most memory. System apps are also running.
