Firefox does not release the memory of the tabs closed, what can I do?

I've known a lot of instability with FF for a few months now and have finally begun to understand the source of the problem.

By checking on: memory, I determined that FF is not releasing memory from closed tabs. I see at least 15 compartments corresponding to the tabs I have looked and have closed less than an hour ago. Try to GC, CC and "Minimize the use of memory" all are ineffective.

Maybe it's a plugin? I disabled all plugins except flash. And in regards to add-ons, I'm under flashblocker, adblock pro, and have installed firebug and colorzilla.

Some add-ons are known to cause problems like that; You can try running with disabled modules to see if they are the cause of the problem.

15 Firefox will include a fix that prevents one of the main ways that add-ons and other code can cause the closed tabs memory leak. You can test a pre-release of Firefox 15 today to see if it solves your problem: https://www.mozilla.org/firefox/aurora/

  • From 50.0, Firefox will not load the tabs. How can I treat?

    Recently (very probably coinciding with the 50.0 update), Firefox suddenly stopped loading tabs. All the pages get stuck on 'connection '.... "as well as system as topic tabs: support and about: config. Google.com and other Web sites and locations internal intranet do not load.

    The first tab that opens at the start of Firefox will sit on a white page indefinitely, not to load the page speed dial 'shortcut '. Not even the tabs system such as topic: support load. If a second tab is open, and the first tab is closed, then the tabs system become available, but websites will always be blocked to 'connection '.... »

    This troubling behavior began to appear in dozens of jobs in our Organization. On each of them, except one (so far), we were able to resolve by obtaining: support to load using the method described above and refreshing of Firefox, which leads me to believe there is some sort of problem with the profile.

    On a desktop, Firefox seems to work after a refresh, but after an instance of Firefox is closed and a new opening, the new question asserts itself. When you open Firefox under a new user profile, it works once before breaking. On this particular station, I tried uninstall Firefox and reinsert several times without success, as well as facility nightly, which presents the same exact issues as the regular version. I'm stumped on how to solve this problem for the end user. I even tried to run CCleaner.

    Any ideas?

    Hi HaggenIT, can you please try the following and see if it works: enter Subject: config in the address bar of firefox (confirmed the message information where it appears) & search for the preference named browser.tabs.remote.autostart.2. Double-click it and change its value to false.

  • Firefox does not save the tabs after the upgrade of Microsoft Silverlight.

    A Web site that I visited recently demanded that I update to the latest version of Silverlight. I did it, and Firefox said it had to be restarted. When I restarted Firefox, even if she asked me to save my tabs this initial reboot, my tabs have not been saved. Now, every time I close Firefox, the warning that I am about to close x number of tabs appears, and there is no option to save my tabs. Clearly, the Silverlight upgrade has been the cause of this error, but how to re - activate the option to save the tabs?

    You can check the startup parameter:

    Tools > Options > general > startup: startup of Firefox:

    Show my windows and tabs from last time

    Show my home page

  • 26 of Firefox does not load the home page. Instead, it loads the previous session (and that includes all tabs). It does not matter how Firefox is closed.

    26 of Firefox does not load the home page. Instead, it load the previous session, regardless of what has been entered in 'Options '. The browser runs in Win 7.0 64 bit; Norton Internet Suite 21 provides security features. There are some solutions 'cloud', also running as Google Drive, box, Skydrive and Cubby. The browser behaves in the same way in all my machines (installation and the OS is similar to that described above) and no amount of reset 'Options' seems to affect it. Nor is it affected by the way that Firefox is closed. This is obviously a bug that should be fixed.

    You can check if you have a user.js file in the Firefox profile folder that affects the pref browser.sessionstore.resume_session_once true value.

    You can use this button to go to the Firefox profile folder:

    • Help > troubleshooting information > profile directory: see file (Linux: open the directory;) Mac: View in the Finder)

    Today, I solved the problem by myself. It took a lot of registry changes and a re - install. He is currently working.

    Thanks for your help.

    Do you hear the names and passwords in the password manager or do you mean that you are connected is no longer on to (remember to) Web sites after the closing and restarting Firefox?

    There is a difference between remembering the name and the password in the password manager and a check box "remember me" on a web page.

    The latter usually involves the creation of a special "remember me" cookie that is stored on your computer and which is sent to the server.

    If that "remember me" cookie is deleted or is corrupted or is not send to the server, then the server remember that you and you must connect once again.

  • Firefox does not display the changes on the site after the remote host; Refresh does not work

    I recently had to reinstall Windows 7 on my machine, and since it has been wiped off I installed CS5, reconfigured my Dreamweaver site and made changes to our page index.html (so far).  After you put the files on my remote server, I noticed that Firefox does not display the changes I made to this file - it is to show the page previously recorded on my CS4 version.  Thinking it was a cache problem, I emptied, refreshed/reloaded several times, restarted Firefox - nothing has worked.

    I checked the page in IE8 and all changes are not displayed correctly.  I used BrowserLab to display a preview in IE, Firefox (same version 3.6 which I use) and Safari, and all 3 display correctly version update of the page.  Visualization in 'live' of Firefox seems to be the problem, and I've looked everywhere for answers. Help is needed and appreciated!

    It is possible that you redefined the site incorrectly and put the files to the wrong address on the server. Carefully check both your local and remote sites definitions.

    As a general rule, it allows to uninstall completely all the previous versions of Flash Player before installing a new one.  See the following articles:

It shows what im running, but there any options at all as the winger treat ect. the window is not even an exit or minimize the icon as other windows are in the upper right. the only way to close it alt f4 do - what I do?

    Looks like you may have a virus or other malware. Get your updated antivirus program and boot into Safe Mode. Note that some viruses can hide from your normal antivirus program, so you really need to scan in Safe Mode. To enter in Safe Mode when you turn on first, press F8 on every seconds until you get the menu, and then select Safe Mode. Then run a complete system scan.

    If that suits him fine. If this is not the case, use system restore to go back to an earlier date at the beginning of the problem. To run system restore, click Start-> programs-> Accessories-> System Tools-> system restore. Click on the box that says show more restore points.

    You can check the corrupted system files. Open an administrator command prompt and run SFC if the above does not help. Click START, and then type sfc in the search box, right-click to SFC. EXE and click run as administrator. Then, from the command prompt type sfc/scannow.

    Finally if all else fails, you can look at the rather cryptic system event log. To make, click Start-> Control Panel-> administration-> event viewer tools. Once in Event Viewer system log-click and scroll entries looking for these "error" with indicator see if you can find guidance on where the problem may be.

    I hope this helps. Good luck.

  • I can't sync my iPod to Windows Media Player. WMP does not recognize the iPod and I can't drag music files between them

    My iPod is connected to the computer and it works fine with iTunes.  But I can't get the music in Windows Media Player to iPod.  When I try to sync in Windows Media Player, it does not recognize the iPod, and I can drag files from WMP to iTunes or the iPod.

    You cannot synchronize an Apple product in itself using WMP, unless you buy a 3rd party. You must use iTunes.

  • The Inbox in the mail application does not all the messages that I can see through the Web browser

    I have a similar problem with the Mail application on Surface 2. Inbox does not all the messages that I can see through the Web browser. I chose E-mail download of any time in the account settings. But when it sync randomly takes messages in the Inbox to display. I uninstalled the app, restarted the Surface and again installed in the Windows store. But the problem remains. It's frustrating. I think the app is not fully developed.

    His works now. I did the sync and other things with no results. Then I noticed that my missing messages are somehow appearing in the file of the Newsletter. Then, I moved all the messages in the Newsletter folder in Inbox and unchecked it parameters. It's working now. There are apparently some bugs in the software that allows for the Newsletter to divert messages. In any case thanks for checking.
