    PS You can also try running SpeedyFox to periodically clean up FireFox. Download here:
    SpeedyFox - Boost Firefox,Skype,Chrome,Thunderbird in a Single Click! | CRYSTALIDEA Software

    Note: Installation is not required. Just download and execute it periodically to clean up Firefox's SQL databases. Now, the unchecked growth of Firefox's SQL databases may or may not be part of your problem but I thought I'd give you a link to the program so you could try it out.

    Cheers
    Hi,
    Thanks for your reply, I restarted so right now its not happening, i installed MemoryFox and Memory Restart for Firefox to see what happens, I have 4 days so far and memory @ 13%. I will let you know and post screenshots if it happen again.

    If there are any suspended VM's, those might be the issue because they don't show up all the used memory in Task Manager (only on Linux).

    How much is it used after a PC reboot?

    You have a lot of programs but if a leak was the cause, others should have experienced that as well.
    If this didn't happened when the OS was fresh then it might be from some program added afterwards.

    When looking at high physical memory consumption, you want to look at Working Set, not Commit. Working Set is the representation of how much physical memory a process has associated with it's virtual address space, so sorting by commit isn't going to necessarily correlate directly with memory usage.

    It'd probably be best to get a snapshot of RAM with RAMMap, and then whichever process seems to be utilizing the most (if any), taking a snapshot of that process directly with VMMap. Both of those tools can be used to save a file that can be posted here and reviewed if necessary.

    Had to figure where to enable this myself. Thanks a lot!

    Seeing that in Task Manager:
    I didn't know where that was hidden but I've finally enabled the view.

    For those looking at this and don't really know where to begin here it is:
    -go to the Details Tab in Task Manager and right click on any table title item and choose "Select Columns"
    -one of those columns is "Working Set" (this is not the Private one we get by default)

    A short example:
    I'm running a VM with 2GB RAM on Win8 x64 host:
    Click image for larger version
    The total OS usage is 3.7GB. But counting the Private Working set or what we see in the default memory table doesn't add up.

    Going to details and selecting the column just as explained above you see this:
    Click image for larger version
    The working set of the running VM VMX process is 2307524K and means roughly 2GB The Private one is just 46436K just about 45MB.

    Now all is clear, you should be able to sort the new list and see which process uses a lot of memory.

    The screenshot is useful because we see 2+GB in the VMs, but I still need a RAMMap save state to be able to give you any concrete data, as I had asked for earlier.
