Firefox 4.0b13pre (2011-03-11) on Linux appears to have a memory leak.

FireFox with 12 tabs open (cnn, msnbc, the.register.co.uk, slashdot, biowar, infoworld, facebook, ebaumsworld, chase online, housereparitalk, meritline, and chicagobusiness) has a memory leak and, before a restart, had used almost 3GB of resident memory. The CPU utilization (4 cores) had gone up to almost 7. Unfortunately, I'll have to go back to Chrome until this bug is fixed as I can't have this affecting my machine like this.

It would be helpful if Mozilla could provide a memory profiling tool that would help us civilians track down memory problems either in the core products or in extensions. The suggestions to create new profiles, re-add extensions, and do A/B (C/D/E) testing along the way, while accurate, aren't practical when we discover that FF 4 on Win 7 is using north of 1GB of memory.

  • Firefox 21.0 on OS X 10.8.4 still has a memory leak that occurs with no Add ons, 1 tab and leads to 3GB of memory usage in 10 minutes.

    While using Firefox 21.0 on OS X 10.8.4 with 4GB RAM, Firefox memory usage marches up and up until at 3GB (on my iMac) Firefox hangs and is 100% non-responsive and must be killed with Force Quit. It takes 10 minutes to occur.
    No Add Ons
    One tab

    John99,
    Unfortunately, the problem was WORSE in FF 22.0. I regressed to FF21.0 and shut off automatic updates. I may even go back to FF3.6, which is the last one where I didn't see this problem.
    Thank you for trying but as a longstanding developer I know that pervasive memory leaks is a sign of a broken development process. Thank you for trying...

  • How do I report a major memory leak problem with Firefox 3.6.10 in WinXP?

    After I installed Firefox 3.6.9 on a WinXP desktop, I occasionally had minor memory leak problems, reflected by getting "out of virtual memory" messages. I upgraded to 3.6.10 when notified that it was available and that it supposedly fixed stability problems. Ever since then, whenever I use Firefox, it starts out quick as a flash, but very rapidly slows down to a crawl, and has twice brought my system to a halt. IE does not cause this, nor any other program I use, but the execution speed of all programs slows as badly as Firefox. If I knew where to get older versions, I would back up to 3.6.9 or earlier. The situation now prevents me from using Firefox much at all.

    Im running windows 7, Firefox 3.6.10 and before i updated to 3.6.10 my CPU never went above 10% with Firefox open. Now it can spike well above 50% and i have nothing different from when i had 3.6.9 to now when i have 3.6.10.
    There is no evidence for me to suggest one of the additions i have is causing it, its all pointing to Firefox itself and the last update.

  • How can I address a memory leak problem with Firefox?

    I have happily used Firefox for the past 7 years, and have rarely had difficulties. However, I am having some trouble now; Firefox (running 3.6.6) seems to have a memory leak on my machine. It's slower than what was discussed in other forum posts, but it still scales up slowly to multiple hundred MBs of Memory with very little CPU usage.
    I have tried disabling add-ons and extensions, but this does not stop the problem. I have cleared my cache and other stored data, but that also does not help. Has anyone experienced a similar problem that might be able to help?
    == This happened ==
    Every time Firefox opened
    == within last two weeks

    Hi reble0708,
    I have Java console disabled on my Firefox browser.Everything is working fine for me. There maybe other problem on your browser which is making PDF document faded and blurry. Can you post the link where you found the problem viewing the PDF document?
    Btw, you can go to ftp://ftp.mozilla.org/pub/firefox/releases/ and select the previous version of Firefox from the given options. There's no need to uninstall Firefox before you downgrade to the previous version of it.But before new installation, backup your Firefox profile folder.
    edit: replaced random unofficial download site link.

  • I am getting a memory leak that sometimes leads to an unresponsive Firefox, but does not crash per se.

    Hello, For the last couple of months, I am having issues with one of my tabs or the program itself causing a memory leak. I was hoping that subsequent releases would fix the problem, but when I downloaded V.11 it did not help.
    I use tab mix plus and at any time, usually have about 25 tabs open. Everything functioned okay for 8 or so months up until recently.
    I am wondering if there is a way to try to track down what is causing the leak. If it is one of my open pages, i will get rid of it. I tried opening one page at a time from scratch, but could not find the issue. .
    I always have flash block enabled to cut down on the website junk.
    using OSX firefox v11.

    Now, I'm not going to say it's an Add-On problem because from the research I've been doing on this problem for the last half hour shows that everyone has DIFFERENT add-ons, but everyone's having the SAME problem....
    So I went through my add-ons and disabled them one by one, and the single add-on that has been giving me grief is the latest WOT add-on. So, I have Firefox 11 (so does my wife) and we both have the WOT add-on. But that's where the similarity ends... I have Windows 7 x64, she has Windows XP x86.... but she doesn't have the memory leak problem.
    What I see is a sawtooth pattern over time. Memory goes up a little over 30+ seconds, then drops down. But over half an hour, the peaks of the sawtooth are larger, and it doesn't drop back down to the same level again - always a little more than before. And before you know it, FF is peaking at 1.5+GB, dropping down to 1.2GB... and FF is running very, very slowly.... excessive disk accesses (paging probably, though I apparently I still have 1.5 to 2.0 GB of free RAM). Killing FF frees it all up, and if I open FF again, it's back to using 250MB of RAM.
    So, it's not the add-ons per se, but how they're interacting with FF (or the other way round).... most likely, it's this plug-in container they created to stop add-ons from taking FF with them when they crashed. Seems to have created more problems than it has solved..... would be great if you could choose not to use it....

  • Memory leak under GNU/Linux when using exec()

    Hi,
    We detected that our application was taking all the free memory of the computer when we were using intensively and periodically the method exec() to execute some commands of the OS. The OS of the computer is a GNU/Linux based OS.
    So, in order to do some monitoring we decided to wrote a simple program that called exec() infinite number of times, and using the profiler tool of Netbeans we saw a memory leak in the program because the number of surviving generations increased during all the execution time. The classes that have more surviving generations are java.lang.ref.Finalizer, java.io.FileDescriptor and byte[].
    We also decided to test this simple program using Windows, and in that OS we saw that the memory leak disappeared: the number of surviving generations was almost stable.
    I attach you the code of the program.
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;
    public class testExec
        public static void main(String args[]) throws IOException, InterruptedException
            Runtime runtime = Runtime.getRuntime();
            while (true)
                Process process = null;
                InputStream is = null;
                InputStreamReader isr = null;
                BufferedReader br = null;
                try
                    process = runtime.exec("ls");
                    //process = runtime.exec("cmd /c dir");
                    is = process.getInputStream();
                    isr = new InputStreamReader(is);
                    br = new BufferedReader(isr);
                    String line;
                    while ((line = br.readLine()) != null)
                        System.out.println(line);
                finally
                    process.waitFor();
                    if (is != null)
                        is.close();
                    if (isr != null)
                        isr.close();
                    if (br != null)
                        br.close();
                    if (process != null)
                        process.destroy();
    }¿Is anything wrong with the test program we wrote? (we know that is not usual to call infinite times the command ls/dir, but it's just a test)
    ¿Why do we have a memory leak in Linux but not in Windows?
    I will appreciate any help or ideas. Thanks in advance.

    Hi Joby,
    From our last profiling results, we haven't found yet a proper solution. We think that probably the problem is caused by the byte[]'s/FileInputStreams created by the class UNIXProcess that manage the stdin, stdout and stderr streams. It seems that these byte arrays cannot be removed correctly by the garbage collector and they become bigger and bigger, so at the end they took all the memory of the system.
    We downloaded the last version of OpenJDK 6 (build b19) and modified UNIXProcess.java.linux so when we call its method destroy(), we assign to null those streams. We did that because we wanted to indicate to the garbage collector that these objects could be removed, as we saw that the close() methods doesn't do anything on their implementation.
    public void destroy() {
         // There is a risk that pid will be recycled, causing us to
         // kill the wrong process!  So we only terminate processes
         // that appear to still be running.  Even with this check,
         // there is an unavoidable race condition here, but the window
         // is very small, and OSes try hard to not recycle pids too
         // soon, so this is quite safe.
         synchronized (this) {
             if (!hasExited)
              destroyProcess(pid);
            try {
                stdin_stream.close();
                stdout_stream.close();
                stderr_stream.close();
                // LINES WE ADDED
                stdin_stream = null;
                stdout_stream = null;
                stderr_stream = null;
            } catch (IOException e) {
                // ignore
                e.printStackTrace();
        }But this didn't work at all. We saw that we were able to execute for a long time our application and that the free memory of the system wasn't decreasing as before, but we did some profiling with this custom JVM and the test application and we still see more or less the same behaviour: lots of surviving generations, at some point increase of the used heap to the maximum allowed, and finally the crash of the test app.
    So sadly, we still don't have a solution for that problem. You could try to compile OpenJDK 6, modify it, and try it with your program to see if the last version works for you. Compiling OpenJDK 6 in Linux is quite easy: you just have to download the source and the binaries from here and configure your environment with something like this:
    export ANT_HOME=/opt/apache-ant-1.7.1/
    export ALT_BOOTDIR=/usr/lib/jvm/java-6-sun
    export ALT_OUTPUTDIR=/tmp/openjdk
    export ALT_BINARY_PLUGS_PATH=/opt/openjdk-binary-plugs/
    export ALT_JDK_IMPORT_PATH=/usr/lib/jvm/java-6-sun
    export LD_LIBRARY_PATH=
    export CLASSPATH=
    export JAVA_HOME=
    export LANG=C
    export CC=/usr/bin/gcc-4.3
    export CXX=/usr/bin/g++-4.3Hope it helps Joby :)
    Cheers.

  • On a Windows 7 computer I installed Firefox 9.0.1 and in my edit menu I have NO Preferences at the bottom, so there is no way to adjust any settings

    On a Windows 7 computer I installed Firefox 9.0.1 and in my edit menu I have NO Preferences at the bottom, so there is no way to adjust any settings The edit menu opens up and I have undo, redo, cut, copy, paste,delete,select all, find....but NO Preferences at the bottom. This is a new laptop and nothing like skype is installed. The Firefox install is new today 1/6/12

    Hi bruce,
    What are you actually looking for? On Windows 7 your options will be under ''Tools > Options''. If you have the ''Firefox'' menu, you can hit ''Alt'' to temporarily enable the menu bar.
    Your System details say Linux. Your say you are on Windows 7 though, correct?

  • Memory leak in firefox 3.6.24 on ubuntu 10.04

    I am using Mozilla Browser on Ubuntu 10.05 Linux system that comes installed with that version.
    As i am having a website running over it and only a single page which is also not very heavy, but when i navigate from one page to other page of the website the memory utilization the Ubuntu system increases and does not drops/reclaimed back. This results in crashing of any process on the system and also sometimes there is so less memory that no process on the system is running except some kernel processes.

    Update to a supported OS
    This is not an Ubuntu Support forum, but one immediate problem is that you are running unsupported and outdated Ubuntu software. Ubuntu 10.04 was EOL 2013
    * http://en.wikipedia.org/wiki/Ubuntu_versions#Table_of_versions
    * http://fridge.ubuntu.com/2013/03/19/changes-in-ubuntu-releases-decided-by-the-ubuntu-technical-board/
    I just booted an old Ubuntu lucid, and that was using Firefox (Canonical) 20. No doubt that was the last version of Firefox available when support ended.
    You probably will be able to run & install Firefox Mozilla 27 on that if you tried, but I have not tried that myself.
    I am posting this from Ubuntu 12.04 precise using Firefox(Canonical) 28 and also have various Firefox Mozilla versions installed.
    You appear to have posted from a Windows7 64 bit computer. If you use an up to date Ubuntu your distro will have an up to date matching Firefox Canonical. You will have a choiceof 32 or64 bit Ubuntu. If however you happen to go down the route of Mozilla Firefox note the default download offerings are 32bit builds, although 64bit are available as ftp downloads.
    If you follow the instructions in
    *[[install firefox on linux]]
    ** '''edit''' and https://help.ubuntu.com/community/FirefoxNewVersion/MozillaBuilds
    that is an additional version. It does not remove your distro install of Firefox.
    Whatever route you take remember to backup the Firefox profile and put it somewhere safe. Just in case anything goes wrong. (Remember you probably have an encrypted Home Directory/Partition ) It is now possible to upgrade automatically no need to do it manually

  • Memory leak in OCCI/libclnts on Linux RHEL 5.5 ? Please advise...

    Hi all,
    Starting with some background:
    I have an application that has been running on 32-bit Linux server for years without problem, a few weeks ago it was ported to 64-bit RHEL 5.5 (compiled with -m32). Now with the application in the new environment some processes are growing in memorysize.
    I have tried to pinpoint the memory leak with Valgrind and have numerous leaks reported in "libclntsh.so", "libocci.so" and "libnnz11.so"

    There has been quite a few changes due to the new server. New compiler (gcc) from version 2.96 to 4.1.2, new version of oracle client 10g to 11g (11.2.0.2), new version of OCCI (also 11.2.0.2). The applications sourcecode is pretty much unchanged though, and that is why I turn to all of you for help.
    Is there anyone who knows anything about this problem and how to even start to fix this leak (if it even is in OCCI)?
    I can supply sourcecode and/or logs if needed. It is quite a lot of complex code so it might take me a while to sort out the relevant code though...

    Thanks for your input! Tough this post is from some time ago this is still an issue for me I'm afraid, so I appreciate all the help I can get.
    I have stripped down the code to just the basic functions needed to replicate the problem. The pool creation and connections are the same as in our application (which is unchanged since before the porting). Though the following code makes no indications of a leak when run through Valgrind, it still grows when checked in "top". It could be that I stripped the code too much, but this is pretty much what our application does. It creates a database lock (not in this code), creates connection, (read table), terminates connection and release lock every 6 seconds to check if there is any new assignments added...

    Above code is built with the following makefile:

    -I$(ORACLE_HOME)/rdbms/public

    Hopefully someone can make sense out of this....

  • Firefox 17 huge memory leak

    Since the last update today, Firefox seems to got a huge memory leak. After one hour idle on some pages it was up to 750MB memory usage, and constant 100% load of one CPU core.
    Looks like something is not going well with the garbage collection, if I visit http://www.robertsspaceindustries.com/forums/forum/forum-category-2/ for example.
    Had to disable the graphic hardware acceleration, because of the newly introduced "clear type" font bug.
    Edit: May also be related to mail.google.com, which I have running in an app tab.

    For what it's worth, I had exactly the same problem (except that it's on Linux) since the upgrade to 17.0. When I disabled greasemonkey, the problem instantly disappeared, so it looks like the compatibility with greasemonkey got broken.
    Likewise, I'm very disappointed with the frequent bugs/annoyances that come with the rolling upgrade system; I find myself more and more using Chromium because of it. Mozilla really needs to give people the option to run a stable branch that receives security updates only.

Means if files name is "1,docx" when i download from firefox it download in that form "1". after download i have to rename and give the extension name is plz tell me the way that office files are compatible with it.
    == This happened ==

    In Firefox Options / Privacy be sure "Remember download history" is checked. To see all of the options on that panel, "Firefox will" must be set to "Use custom settings for history".
    To find your OS information, on your Windows desktop, right-click the My Computer icon, choose Properties, under System on that small window is info about your OS.

  • Firefox memory leak, how to fix?

    I've noticed i've been having memory leaks since quite a few versions before the latest one (33.1.1) and the problem still continues, i notice this more when i leave firefox open for awhile, sometimes only with youtube and couple of other "static" pages on, but i've got the same results without youtube.
    Today i decided to ask the question, since i haven't seen any memory leak bugfixes in the recent changelogs and it becomes quite a problem to me because i leave it all day open and when it happens it forces me to restart (not really forces but i don't like having an 1.3GB process when i can have the same for 500~ ...)
    I don't believe any of my extras are the reason for it, i've tested them over the pass'ed versions, removed a few, installed a few, always same problem.
    All of this running WIndows 7 Ultimate 64-bits .
    i've researched and found it's a "common" problem, but no really solution or expected bugfix soon or anything, i'm still to test it without any 3rd part extensions or plugins, but i don't (think) have any extensions that may cause this because like i said, i've changed them quite a few times.
    Here is my extension list: http://i.imgur.com/Rk80ajU.png
    Here is my plugin list: http://i.imgur.com/GBA0qgY.png
    And here is a "Measure" report from "about:memory" : http://privatepaste.com/bcd17c1093
    I just want to know why it leaks so badly, almost the double RAM it would normally use.
    Currently i'm like 3 tabs with 1.25 GB (Private Set) used, when i close a few tabs, it keeps stable or even rising by a few mb.
    I hope there's something useful with that report/my extensions|plugins.
    Thanks for the reading.

    I heard about that extension "problem" but, when i see on "about:addons-memory" from a third-party extension (that i can't remember but yo can see it in the link on OP, it only uses few megabytes (20~) , so, either it's a memory leak on the extension (if that's really the cause) a problem with my addon to view the extensions memory or a firefox one.
    But i seriously don't expect that extension eats up all of this memory, but i will test it in a couple of days.

  • Firefox insists on freezing computer while checking for updates I have said not to check

    Firefox repeatedly checks for updates of disabled addons. I have DO NOT CHECK FOR UPDATES enabled, but . . . WTF FF ignores my options as if they weren't entered. I've done all I can.
    I'm pretty tired of trying to open FF and being delayed while FF pleasures itself at my expense.

    Yes, the Intex website does say that the phone has v1.3 installed. (http://www.intexmobile.in/product_detail.aspx?PID=191&PCatID=3#)
    But in the settings it says that the software version installed is '''Intex_cloud_FX_V07''', and the update channel is '''release-spreadtrum'''. Does it mean the Intex uses its customized version of the OS? If so, how do I switch to the ''un-customized'' version.
