What a joke.  This is not a leak, this is thousands of leaks.
No it's not. Obviously you have no knowledge of this topic at all.
Making sure memory is properly managed should be a TOP PRIORITY for any software.

And knowing what you're talking about should be a TOP PRIORITY for anyone starting a new thread. In essence what you're doing is trolling. Everybody knows that firefox has memory leaks, you know that the firefox fanboys will deny it, so you start a thread about it. It's not wanted.
No it's not.  Obviously you have no knowledge of this topic at all.

Really? How so? Please point out any of what I have said to be false.

Ok.. this is a bit different actually. This involved a multitude of leaks in a matter of 60-90 second usage. The problem everyone knows of is with using it for extended periods of time and having it keep using more and more memory.

This thread was not an attempt to troll at all. I'm sorry if you think so, but you're not me.

I imagine your browser uses the IE shell. Why code your own? I'm not trying to be a dick, I'm just curious is all.

Uhhhhhhhhhhhhh no I dont use an I.E. shell or any other shell I  designed it and me and few others coded it I dont use any thing ms cept on one machine. everything is mine/my companys. and before you ask no we dont code it in C or any variation of  c or any  known computer language for that matter. thats why we dont have the issues we do that most others do.

Well mind even stating what the language is called? What platform? What does it support? I'm honestly curious. I've given thought to doing basic browser prototypes and if you really have designed your own browser, I wouldn't mind asking a few questions.
When I used Firefox, mine was hitting around 200+ MB of ram with two or three tabs open using no extensions.

The product is a complete failure at this version number.

3 tabs open, several extensions, 24MB of ram....hmm....

Open a site that has hundreds of high res images in those three tabs. That's not really the memory usage that he's talking about.

I believe the thread starter is talking about memory being wasted after FF is closed (or so I think). I've never noticed that problem nor do I think it is a big deal.

Well mind even stating what the language is called? What platform? What does it support? I'm honestly curious. I've given thought to doing basic browser prototypes and if you really have designed your own browser, I wouldn't mind asking a few questions.

First off even though the language doesnt officially haave a name yet we are calling it X for right now. it will run on both IBM and apple machines so cross platform. When we set out to do it we decided on few basic things. 1. had to be different then all other browsers, with more features and fuctionality. 2. it had to demonstrate our

belief that you can have 100% secure and safe. anyway it took us about 2 1/2 years and we have been testing it quietly here internaly and in real world enviroments. if you wanna ask questions pm me or e mail id be happy to answer whatever. c( cept for screenshots and code samples in few months perhaps ) :)

Personally I like firefox and don't notice any memory leaks that may be there. I'm not a fanboy or anything, but I just see no performance hit or anything. I suppose I use firefox because it seems safer than IE, but I also like it. Hopefully if this memory problem is big, it'll bet fixed! :rofl:

Really?  How so?  Please point out any of what I have said to be false.
I already did, but I'll repeat it since you didn't read my other post: your claim that firefox has thousands of memory leaks is a lie.
you're not me.
Thanks for the clarification. How old are you, eight?

Did you even read that log you posted? I don't see anywhere that evidences thousands of memory leaks.

No, it's not.

Maybe you should think before you post. Each one of those IS a memory leak.
did you have any extensions installed?  i noticed that when i have certain extensions installed i get poorer performance than if i had no extensions installed.

585516570[/snapback]

Yes, I had a bunch of extensions installed. I'm trying to zero in on which one may have caused it, but I'm having trouble with freezes at the moment.

your claim that firefox has thousands of memory leaks is a lie.

No, it's not.

585516588[/snapback]

Well then why don't you provide some evidence to support your claim?

Each one of those [lines in log] IS a memory leak

Actually thats a lie also. That log is a list of all the times firefox allocated memory, not of memory leaks. You really have no idea what you are talking about. Really no idea.

I've found that Tabbrowser Preferences slows down a Moz installation quite a bit, although I've not tried it on Firefox, so I can't be sure.

As for the memory leaks that vcv found, I don't know why he's getting so much heat for it. If anyone is unhappy with this thread, or thinks he's trolling, then just leave the thread. You don't have to sit here and complain about it.

To add something more constructive to the issue: it does seem likely that the memory leaks are relating to extension management by the Moz framework. A lot of the extension management functionality seemed to have been added to Firefox in the last 2 or 3 point releases of the app, although I'm not a Moz developer so I wouldn't know if this would cause memory leaks or lead to higher probability of leakage.

As well, could the answer to extension manager problems (including memory leaks) be in a revamp of the way extensions are registered and handled? The Mozilla Wiki section on chrome registration mentions some problems associated the current chrome registration system and that the revamp should address those issues. Again, I can imagine that this might be related to memory leaking in relation to the extension management system, but of course, this is speculation on my part.

Would be great to hear from someone involved with the Mozilla project, if anyone here occupies such a role. :)

I've been reading through this thread and some people just don't understand what is going on.

vcv is stating that memory is not being freed up when FF closes. He is not talking about runtime memory allocation!

How many times are people going to ask that question?! :blink: :s

Well then why don't you provide some evidence to support your claim?
Uh.. I did. The export log, the screen shot. Anyone can run the program on Firefox for themselves as well.
Actually thats a lie also. That log is a list of all the times firefox allocated memory, not of memory leaks. You really have no idea what you are talking about. Really no idea.
This is really infuriating. Have you used the program?

IF what you say is true (which it is NOT), then why do other programs only show a few things in that list after they are closed? Do you not see the caption of the window that says "Leaks Result".

----------

Now.. I tried this with the latest nightly and TBE installed (nothing else).

I have the homepage set to default (google).

I Opened a new tab, and clicked the home button in the new tab.

When the page was finished loading, I closed the first tab.

I repeated this 10 times. I wanted to see if loading the same page causing it to keep using more memory.

Results:

2829 leak(s) found in 3.624 seconds.

So I think it's narrowed down a bit. I'll play around more and see if I can get some more progress on it.

FF Nightly / TBE Extension

Refreshed home page once, closed FF.

6 leaks found

FF Nightly / TBE Extension

Created new tab with double click, closed FF.

7 leaks found

FF Nightly / TBE Extension

Created new tab with double click, clicked home page button, closed FF.

8 leaks found

FF Nightly / TBE Extension

Created new tab, clicked home page, closed original tab, closed FF.

2881 leaks found

FF Nightly / TBE Extension

Created new tab, home page, closed 2nd tab then first, closed FF.

7 leaks found

-----

Very peculiar results. I repeat each test twice to make sure, and got the same results. I repeated the 2nd last one 5 times with the same results.

Can anyone else try these to see if they get similar results?

edit: Tried same thing with TBE uninstalled, same results. So it doesn't appear to be TBE.. and no other extensions are installed.

vcv:

Why don?t you download the source code , take a quick look through it , fix the leaks,compile it, run your test again and provide us with a link to a fresh nonleaking Firefox build , I?ll be back tomorrow ,downloading your fixed version...:woot:t:

Regards WinCC

Extensions:

I have about 20 installed.  I will run again on a clean install.  However, extensions are not responsible for the memory management, FF is.  So this is still a problem regardless of whether or not its the extensions.

First off, it seems you have no idea how things work. Let me explain to you then..

Firefox loads pages into memory. When Firefox closes, most of it's memory allocations are deallocated. Extensions CAN allocate their own memory, and if badly coded, may not close them. Firefox cannot be held accountable for all it's third party extensions.

Plus nowadays we a thing called Virtual Memory. This makes memory leaks much MUCH less of a problem. Memory leaks aren't *real* memory leaks until all your virtual memory is depleted. How often is this a problem? Rarely. With Firefox? Never.

Yes there is a memory leak in FF, usually happens when you use tabs.

Regarding the memory eating by FF..... found the following at http://forums.mozillazine.org/viewtopic.php?t=172041

"type about:config into the location bar, press enter, right click any line, choose "new">"integer", paste this into the dialogue that appears:

browser.cache.memory.capacity

click okay, specify the amount in kb in the next dialogue that appears, restart firefox. -LeRoi"

You originally stated that this is not an attempt to troll, rather an attempt to warn others about Firefox's major memory leaks.

According to your own tests and results:

Firefox does not have "thousands" of memory leaks like you originally stated. In fact, Firefox has less than 10 memory leaks. It is Firefox's third party extensions that have thousands of memory leaks.

Yet you still claim you are right and that Firefox has major memory leak problems. After your own tests revealed Firefox does not have major memory leak problems, you still contest that it does. This sounds more like trolling than a warning to me.

    • Microsoft making much needed change to Windows 11, 10 Patch Tuesday security updates by Sayan Sen Recently, Microsoft delivered its latest Defender patches for Windows 11 ISOs. These definitions are released from time to time alongside the general security updates available during Patch Tuesday. Speaking of Defender, the company has now announced another important change that affects how security updates are delivered to enterprise devices running Windows. According to a recent announcement, Microsoft Defender for Endpoint's endpoint detection and response (EDR) updates will no longer be bundled with the monthly Windows security updates or Patch Tuesdays. Instead the company is shifting delivery of these updates to Microsoft Update, bringing EDR servicing in line with several other Microsoft Defender components. If you recall, Microsoft last year moved PowerShell updates to Microsoft Update (MU) as well since it provides automatic updates for Microsoft products and services. Thus the move is intended to allow Microsoft to deliver EDR improvements and security enhancements independently of the OS's regular monthly update cycle; this should enable faster deployment of protection updates without requiring organizations to wait for the next Patch release. For those unfamiliar, Microsoft Defender for Endpoint's EDR capabilities are designed to help organizations detect, investigate, and respond to advanced threats across managed devices. Keeping these components updated is critical for maintaining protection against evolving attack techniques. The rollout has already began for Windows 10 devices in late May 2026 (last month) and Microsoft says it will gradually expand support to Windows 11 and the remaining supported Windows versions over the coming months. The company expects deployment across Windows 10 and Windows 11 to be completed by fall 2026 or around Q3 of this year. Once the transition is complete, EDR updates will be delivered through Microsoft Update using KB5005292, provided the required prerequisite updates have already been installed. Microsoft is also introducing a new Defender Update Service as part of the change. Following installation of the first update, devices will automatically create a new directory located at %ProgramData%\Microsoft\Microsoft Defender\Defender Update. Microsoft notes that restarts may occasionally be necessary in case of "rare" failure scenarios. For most organizations, the tech giant says no action will be required as long as Microsoft Update is already permitted within their update management strategy. Admins who rely on manually deployed update packages, however, will need to adjust their processes to ensure the new Defender update package is included. Microsoft also recommends reviewing internal documentation and notifying helpdesk and security operations teams about the updated delivery mechanism to avoid confusion during the transition. As a prerequisite, the tech giant notes that systems must be running Sense version 10.8798.25857.1000 or later and have one of the following Windows updates (or later) installed: Win11 24H2 KB5062660 (2025-07 Cumulative Update Preview) Win11 23H2 KB5062663 (2025-07 Cumulative Update Preview) Win11 22H2 KB5062663 (2025-07 Cumulative Update Preview) Win10 22H2 KB5062649 (2025-07 Cumulative Update Preview) Win10 1809 KB5063877 (2025-08 Cumulative Update) Server 2019 KB5063877 (2025-08 Cumulative Update) Server 2022 KB5063880 (2025-08 Cumulative Update) Server 2025 KB5063878 (2025-08 Cumulative Update) As always, organizations should verify that their update policies align with the new servicing approach before the broader rollout reaches all supported Windows platforms later this year. In case of major problems, the EDR update can be rolled back to the inbox version stored in %ProgramFiles%\\Windows Defender Advanced Threat Protection (ATP) using: MpCmdRun.exe -RevertMde -Product Edr -ToVersion Inbox For those who have access to the Microsoft 365 Admin Center portal, you can view the message here under ID MC1381119.
    • My problem with these smart scopes is that IMO they're not really an entrance into astronomy, they're an entrance to looking at pretty(ish) pictures that you take by essentially pressing a button and letting the scope do the work. I still maintain that getting some binoculars or a solid dedicated telescope (which doesn't have to mean expensive) and actually spending time learning the night sky and using a telescope is a much better way to actually learn. But, granted, the learning curve is a bit steeper (as it tends to be).

    • The perception of Microsoft Edge is unfortunate as it's a world class browser. I'm not exaggerating when I say it's the best browser I've ever used with its feature set, speed, reliability and advanced security. Running the extension Ublock Origin is a must though to deal with advertising and trackers.
