Why does firefox leak memory up to 2Gb on windows7 64-bits on my Alienware computer but not on my 2 other Inspiron 6400 and 1750?

right now i have only 5 tabs open with information about firefox help firefox memory leak and so on just to try to see if i can find anything about why i have this memory leak and the memory leak is already up 1.3 Gb.

i have the same problem, please do something about it! I have 2gb RAM and after a few hours ff uses 80% of my RAM and additionally 1.5gb of virtual memory. This slows down ff, because of copying data from virtual memory to ram.
I know this is because of caching websites in RAM but it really slows down ff, here is my solution:
1. A user is able to specify maximum RAM to be used by ff
2. Website caches are sorted by last access datetime - now if firefox reaches the max RAM - it removes the oldest website from RAM.
Simple and effective. Damn it.

Why does Firefox leak memory after. I do the same operations in Firefox and Safari, Firefox in some cases uses over 500 MB of RAM, Safari uses about 50 MB

After opening and closing 5 windows in Firefox and Safari, at rest Firefox still claimed (approx.) 500MB of real memory, Safari return all memory and claimed only (approx.) 50MB at rest (all windows closed). My laptop starts over heating when browsing just simple information pages in Firefox. This still happens after updating to the latest browser.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Why does FireFox look for "Chrom..........." when I close the left (last) tag and report "can't open ....? Have i missed an option that wold send it to my hom

If I close the last (left) tab to return to my desktop, firefox tries to load google Chrome and reports to me that it can't find the server.
Apparently, I have missed an option in the help area that prevents this. Any ideas?

Why does Firefox 5 open external (internet, SMTP) e-mail in the browser rather than the Lotus Notes Client?

Using Lotus Notes as the system's primary mail client, '''some''' users experience external mail being opened in the browser rather than the the client. When they revert back to using an older version as the OS default browser, or indeed a different browser altogether, this does not happen.
Again, this does not happen with all installations of 5.0 - just a few.

go to "preferences" in Lotus Notes and enable "disable embodded browser for MIME mail" and it shoudn't open the browser anymore

Why does Firefox 4.0 keep asking me for some "32-bit plugin" item that requires restarting the browser, and then I keep getting the SAME MESSAGE (this only shows up when I am in my Yahoo e-mail!)?

This only happens when I am typing an outgoing e-mail on my Yahoo account!

Please do the following.
Click '''Help '''| '''Check For Updates'''. The option to update should appear and version 3.6.17 should download and install.
However, sometimes things go pear-shaped and you get version 3.5.19. If that happens, repeat the same steps to update to 3.6.17.
Once you have 3.6.17 installed, you'll get the opportunity to update to the current version which is 4.0.1 ''Please don't do that for the moment because you first of all have to update your plugins''. To do the latter, please do the following.
Go to http://www.java.com/en/ and install the latest version of Java.

Why does Bookmarks take several seconds to respond after I move a bookmark when Sync enabled, but not when Sync is disabled?

With FFox open and Sync enabled, moving a bookmark, either in the Bookmark sidebar or in 'Show All Bookmarks' window, to another location - for example: dragging a bookmark from "Unsorted" to another location in Bookmarks - causes a delay during which time the Bookmark list seems to freeze and bookmarks can't be moved, selected, etc. The delay lasts for several seconds, and is longer on slower/older machines. If I attempt to move a bookmark (or folder) during the delay, it will move in unexpected ways once Bookmarks unfreezes as locations within the Bookmark list have changed.
With Sync disabled, bookmarks can be moved/selected/etc. without any delay.
Systems Tested: [Note: All systems had the most current version of FFox available for them.]
MacBook Pro 26 (2014) w/OSX 10.9
IBM ThinkPad T41x (2010) w/XPpro
Macbook Pro 266 (2009) w/OSX 10.6
IBM ThinkPad T61x (2008) w/XPpro
Mac Mini (2008) w/OSX 10.6
Mac Mini (2007) w/OSX 10.5
Macbook Pro 233 (2007) w/Ubuntu v14
ASUS P1AH (2006) w/Ubuntu 12
My main computer is the Macbook Pro 266, and I noticed this behavior: FFox v36 bookmark delay with Sync enabled is about the same as v35, v35 was worse (longer delay) than v34, v34 was better (less delay) than v33, v33 was better than v32, V32 was much worse than v31, v31 was much worse (Sync unusueable) than v30, v30 was much worse (Sync unusueable) than v29, v29 delay made Sync unusueable.

Currently 664 [exported from FFox Bookmarks to URL Manager for the count] abut never more than 4000: beyond 4000 bookmarks and FFoxs' Bookmarks respond slowly even without Sync active. I currently have 5 computer with FFox set up to use Sync. While I don't expect FFox to manage a huge collection of URLs, I would be nice to be able to access a Bookmark collection of 6000 to 8000 without noticeable delay. It's a simple text file after all, and as I'm only effecting one URL, why so long to update?
fyi: URL Manager tells me that I've amassed about 300,000 bookmarks, some from the late 90's which I still use for research.

Why does the port settings on my iPad change every time I sync with my computer. After syncing I have to go in and change the port settings so I can send and receive emails on my iPad.

Every time iSync my iPad 2 with my computer it changes the port settings. Has anyone else had this issue?

When you sync the iPad, do you have mail settings configured to sync to the iPad? You could have different settings on your computer that might be affecting the email set up on the iPad when you sync.

Why does my printer now produce very faint illegible copies? I have changed the cartridges but NOT

I have not changed any settings and have inserted new cartridges but the print quality is very poor - faint greeninsh grey and plae colours on Test Page

Why does syncing take so long? 2GB is taking 215 hours

Why does syncing take so long? 2GB is taking 215 hours

Thats a fair enough comment, but I would have thought that syncing a mere 2GB of data, 215 hours seems a bit ridiculous, especially as it's not explained very well on the Adobe Cloud exactly what syncing is and how it benefits me. My internet connection is BT broadband and my download speed is 10 Mb/s, upload is 0.261 Mb/s crap I know.

Why does Firefox require a reboot after uninstallation?

Basically, my problem was already asked here: https://support.mozilla.org/en-US/questions/916857
But that thread is marked as "solved", when in fact this problem is nowhere near being solved, so I am asking it again in a new, "unsolved" thread.
In former times Firefox never needed a reboot, and it does not make any sense because no Firefox-related file should be in use at the time of uninstallation. (Forget about updating in my case; I am doing a clean uninstall, and Firefox insists in rebooting anyway.)
Windows reboots due to software uninstallations are generally only required in the following cases:
* If files that belong to Windows are being modified. I hope Firefox does no such thing...
* Part of the software being uninstalled is still running, so that its files are in use. However, I completely closed Firefox and even used the task manager to make sure no firefox-related processes were running.
Some applications (i.e. Adobe Reader) install fancy "Speed Launchers" that are loaded at boot time and stay resident in memory. Unless these processes are manually killed before uninstallation, they may also be the reason why a reboot is necessary. However, Firefox should not do such a thing.
To summarize it, the question is: '''Which part of Firefox is running during uninstallation so that removal of the corresponding files is required?
Generally, I consider this a very bad software behavior, one that I would expect from some commercial software producer who wants to install his speedlaunch or logging stuff on my computer, but not from a free project like this one.
Firefox Portable does not do this, easily proving that technically it is not necessary. Earlier versions of Firefox also refrained from doing such a thing.
A piece of software requesting a reboot without good reason is what I consider a bug.

Aw, c'mon. Writing to the Windows registry never requires a reboot. This is ridiculous.
And Firefox did not need that bad behavior up to version 8 either. Why now?
This is not a Windows issue. You cannot alter files in Linux either if they are currently locked. The thing is that there is no sensible reason for any Firefox-related files to be locked at uninstallation time, which is why there should be no problem removing them.
I do not mean to rant, even though I am disappointed by this new behavior and would like to have it changed, but the least thing I really would like to know is exactly what is causing this. Why have the new versions of Firefox been programmed to require a reboot? Exactly which files need to be removed or changed that cannot be removed/changed during regular uninstallation, so that their removal/change needs to be scheduled for the next restart of Windows?

Why does Firefox always block any link I try to open going to a web page when I don't have pop up blocker on?

Why does Firefox always block any link I try to open going to a web page when I don't have pop up blocker on? First off they are not even pop ups....your crap blocks everything and don't save user names &/or passwords when you have it checked. Also in your tutorials about solving this issue says it has the word "OPTION" .......no, it never says option to allow you to bypass it and etc. Only thing is says is "ALLOW" . That would be nice , but the problem is it will not allow it from then on. It only allows it right then and then you have to refresh...after that to open again it blocks it again.....HOW STUPID?!!!!!
It always say that this is preventing this page from automatically redirecting to another page. THIS IS WHAT I AM TRYING TO DO...GO TO ANOTHER PAGE........I DON'T NEED YOUr BROWSERS PERMISSION TO DO THAT. THAT IS WHAT A *%#$&*(&*%$$%% BROWSER IS FOR TO GO TO OTHER PAGES......THEY ARE NOT POP UPS!!!!!
YOU STUPID BROWSER ACTUALLY BLOCKS EVERYTHING AND THAT SUX!!!
HELP!!

Why does Firefox have to make it so difficult to get answers--I am not going to be able to check the website to see what anyone might reply to my question on crashing?

I have no way of checking to see if anyone answers this. Why does Firefox have to make it so difficult?
What does this means: DLL C:\Program Files\Mozilla Firefox\MOZCRT19.dll is not a valid Windows image. Please check this against your installation diskette.
Suddenly all my tabs closed. Then Windows told me I had a gazillion infections. Then a tiny strip appeared saying it was Firefox and these little blocks started to fill up the little strip as if it were downloading something--there was no way to cancel this so I cut the power. Now when I try to use the Firefox icon, I get the message above.
Am I supposed to remove the old Firefox stuff and start from scratch? I am stuck using Internet Explorer.
I went to the Firefox website and tried to download it again, but McAffee jumped in and said there is something wrong with Firefox and I should register with them that I am downloading Firefox (I do not have McAffee). Then I got a security warning saying Firefox is not safe.
I am completely at a loss as to what to do next, since I don't understand any of this mumbojumbo.

Here's the story on one of your infections, namely JS:Redirector-EH[Trj]: http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=Trojan%3aJS%2fRedirector.H
The main problem with malware is that it uses the installation to proliferate by contacting hostile servers to download more of the same rogue code.
Firefox doesn't have the option to "Run" a file. You can only "Save File" or "Cancel". If you downloaded it with IE8, then yes, you can run it, but that's not what I wanted you to do.
What you should do now is to disable System Restore. You can open System Properties by hitting the Windows logo key and Pause/Break key together. Then click the "System Restore" tab. Then checkmark the box which says "''Turn off System Restore on all drives''". Reboot to clear its contents. System Restore unfortunately makes a backup of all executables which includes viruses so that when you reboot without deleting them first, System Restore reinstates them again.
After you complete that step, run Avast and Malwarebytes again to make sure the system is clean.
Then go to the Windows Update site (link on your start menu) and install the missing patches which enabled your machine to become infected in the first place.
Once the system is clean, repeat step one to download Firefox again, but please do not run the file. If you don't see the option to "Save File", cancel the download, but it should be there. You can use this direct download link to download FF4.0.1 [http://www.mozilla.com/products/download.html?product=firefox-4.0.1&os=win&lang=en-US Download Firefox 4.0.1]
Run the file after you download it to the desktop.

Why does firefox show up as a plugin on volume mixer?

Why does firefox show up as a plugin on volume mixer? After updating a flash plugin into firefox (when it had requested me to update it), it no longer shows up as firefox in volume mixer. It now shows up as some plugin icon. I really don't understand this, and wish it to be the firefox icon again. What is going on and what happened? It names itself "Plugin Container For Firefox" What does that mean? It has been this way ever since, and nothing I have done has fixed this. Restarting, refreshing, reinstalling, clearing cache, etc. Can anyone think of something please? :(
== This happened ==
Every time Firefox opened
== This happened just a couple days ago (june 25, 2010 exactly)

I have this, but my volume on firefox doesnt work at all

Why does FireFox change layout/settings during upgrades without asking ?

Just upgraded to Firefox 18 (windows 7 desktop). Why does Firefox change layouts/settings without asking the user if he wants it or not???
I am getting sick of those changes. I want to have at the google main page the options (as before) to search in all languages, or pages from a certain language or pages in a certain language (of course depening of the google address; f.i. at google.de for german languages, google.fr for french languages etc).
In the latest Firefox 17 it was working as I wanted and described before: when I visited www.google.de/firefox of www.google.fr/firefox. Now those 3 options (under the search bar) are gone and I do not want to operate by clicking on the advanced search button. Those things should be visible under the search bar again.
Also my STARTPAGE was GONE/DELETED after the update !!! Grrrrr.... Updating is OK but mozilla should not change user configured items !!!!!!!
The above described problem has nothing to do with the google website.

By the way, do Firefox and IE use the same proxy settings? You can view Firefox's here:
orange Firefox button (or Tools menu) > Options > Advanced > "Network" mini-tab > "Settings" button
The default is "Use system proxy settings".
