How can I get to about:memory?

I want to work on a memory issue with Firefox. One recommendation is to use the "about:memory page," but I don't know how to find it. Will someone explain how to get to about:memory?

Hi bobover3,
It is simple just navigate to it: key in to the addressbar ''about:memory'' then click the green triangle or hit the return key.
Note it allows you to save the results and reload them later. It has buttons to reduce memory usage, and gives information on mouseover of items. Parts will collapse or expand.
* see also [[Firefox uses too much memory (RAM) - How to fix]]
Memory problems may be rather difficult to troubleshoot. It may be worth running something like memtest overnight to check your RAM
*edit see http://en.wikipedia.org/wiki/Memtest86

  • How can I get my old memory out to upgrade? one seems to be frozen

    I am trying to upgrade my iMac.  I have ordered the upgrade but am having trouble getting the old memory card out (one came out pretty easily, but the other won't move).  Also when I inserted the new memory card in the one that would come out, it didn't seem to go in as far as the one that had come out.  I had to just put the old card back in.  Help!

    Here are the complete specs for your iMac:
    http://www.everymac.com/systems/apple/imac/stats/imac-core-2-extreme-2.8-24-inch -aluminum-specs.html
    Now, I've never heard of Axiom, but that does not necessarily mean anything; however, what does is that iMacs are known to be extremely finicky about the RAM.  The brands usually recommended here are either Crucial or OWC (macsales.com) - this would be the RAM you'd need from them:
    http://eshop.macsales.com/shop/apple/memory/iMac/Intel_Core_2_Duo
    As for getting the old stick out, if you can't manage it, I would make an appointment at your nearest Genius Bar and ask them to check out the slot (this is free). Also check on why you can't put the new stick in all the way - it may just be that you're not pushing hard enough, it does require quite a push. If the Genius can't seat the RAM correctly, I'd say there is a problem with the RAM and I'd return it.

  • How can I get informations about PATH variable ?

    I have a programme installed on my computer and I need informations about its path. For example I can get Java home path like this:
    System.getProperty("java.home");, but how can I do that for my programme.
    If you know another way I can do this please let me find out.
    Thanks !

    To sergey35:
    Thanks! This work very well.
    Now I want to launch an application from java, but I don't know how can I test if my application exists (is installed).
    For example if I want to launch winamp or any other application, but how can I verify if my application exists indeed. The end user isn't interested if my application really exists. He push a button and he wants to launch that application. If it doesn't exists I have to notify through a message this fact. And most difficult I think is to know exactly the path where is installed that application.
    If anyone can help me with documentation or suggestions please reply to this thread.
    Thanks!

  • How can I get info. about "shor​tcut menu"

    I can get the menuitem title just like below
      call MenuItemInfoGet("SCRIPT", "M.1")
      MsgBoxDisp(MenuItemTitle)
    but for the shortcut menu , I can't get the menu tiltle like, use"c" instead of "m":
      call MenuItemInfoGet("SCRIPT", "C.1")
      MsgBoxDisp(MenuItemTitle)
    Why?

    Hi Chian,
    MenuItemInfoGet is not supported for shortcut menus because this kind of
    menu is dynamic. That means, depending on the context or customizing a shortcut
    menu can have more or less entries. So it could happen that you get back
    information's which you are not expecting (in case of supporting shortcuts with
    MenuItemInfoGet).
    Greetings

    Hi,
    As this is the Training and certification forum I would suggest to follow training in web development and achieve the Microsoft certification for web development.
    The MCSD certification has a web devlopment track.
    Work experience can unfortunalty only be achieved by actually doing it on the job, you will need need to look for an employer that is willing to invest in you to move on from theoritical knowledge to work experience.
    Good luck with your career in web development.

  • How do I get information about filing a claim for kids purchases

    How can I get information about making a claim for kids unauthorized purchase?

    I have seen nothing formal from Apple though I have read they are open to discussions about the matter.
    If it is an individual instance, there is a  section on the purchase receipt that invites you to report a problem   Report the purchase and the circumstances.
    However, if it is a recurring problem you would have been expected to utilize the parental control features.

  • How do I get information about new legal requirements?

    Hi
    We are 4 people in a company that has 39 active company codes in about 25 countries. How can we subcribe to whenever SAP releases new reports that meets legal requirements in specific countries? Some of our companys have their bookkeeping taken care by a neighboring country, so the bookkeepers would not know if there is a new report released from SAP. So how can we get information about new reports without having to read throug all the release documentation?
    Hope you can help

    Hello Jens,
    this is a real problem.
    What is my experience? The first priority is: try to use the SAP Standard as far as possible. No user-defined reports, no exits. Try to be always up to date with hotpackages.
    A further help for me are the userforums here. If you have five minutes left, just have a look at all the questions and answers.
    I know, there is a lot of stuff to read, but the releasenotes have to be checked. Unhappily I didn't find another way.
    Sometimes SAP reacts just in time regarding new legal requests - and I can understand this. At least I have to say: It is not possible to manage this without having any support from the accountancy side. This enables you to search for this requests - instead of reacting.
    If a country changes statutory requests regarding taxreporting or new taxtypes, changing of rates the guys from local accountancy ought give you a hint. Because they get this information at first.
    I made good experiences with internal accounting forums or user groups (i. e. northern countries, westeurope, USA, southeurope). 
    Maybe it gives you a little help and I am very interested in all the answers to this thread.
    Best regards

  • How can I get all photos from iPhoto to automatically back up to iCloud from my Mac OSX Version 10.6.8 operating system.  Not enough memory to upgrade.

    How can I get all photos from iPhoto to automatically back up to iCloud from my Mac OSX Version 10.6.8 operating system.  Not enough memory to upgrade.

    You can't.  iCloud is not for general file backup from a Mac. It's for backup up and syncing data between mobile devices and and Macs and  The following is from this Apple document: iCloud: Backup and restore overview.
    iCloud automatically backs up the most important data on your (mobile) device using iOS 5 or later. Once you have enabled Backup on your iPhone, iPad, or iPod touch .....
    What is backed up
    You get unlimited free storage for:
    Purchased music, movies, TV shows, apps, and books
    Notes: Backup of purchased music is not available in all countries. Backups of purchased movies and TV shows are U.S. only. Previous purchases may not be restored if they are no longer in the iTunes Store, App Store, or iBookstore.
    Some previously purchased movies may not be available in iTunes in the Cloud. These movies will indicate that they are not available in iTunes in the Cloud on their product details page in the iTunes Store. Previous purchases may be unavailable if they have been refunded or are no longer available in the iTunes Store, App Store, or iBookstore.
    You get 5 GB of free iCloud storage for:
    Photos and videos in the Camera Roll
    Device settings (for example: Phone Favorites, Wallpaper, and Mail, Contacts, Calendar accounts)
    App data
    Home screen and app organization
    Messages (iMessage, SMS, and MMS)
    Ringtones
    Visual Voicemails
    But not from a Mac.  If you want to backup your photos and other important files I suggest you get an external hard drive and use  it with Time Machine.

    You can't. There is no memory card. It uses flash memory that's soldered to the logic board. If you didn't back it up, your data is gone.
