I have a HP Media Center PCm7060n running XP Media Center operating system. I recently tried to open the Task Manager and received the message "Manager tasks has been disabled by your system administrator. How can I activate the Task Manager?
It seems that you might be right, that you need more slashes.
Tracking Add HKCU v DisableTaskMgr /t REG_DWORD 0 f d

I can't get Firefox to open a window. I tried firefox-p (Profile Manager) and firefox-safe (safe mode), but nothing works to open a window. I uninstalled and reinstalled, but that solves nothing. I haven't changed anything recently, so perhaps there is a update (?) Here's what happens:
I try to start Firefox, and the Task Manager indicates that Firefox is running. It employs about 32 k of memory, but the window never opens.
I click Firefox again. Manager tasks indicates 2 Firefox process now. The second is to use about 4 k of memory. Running Firefox repeatedly adds additional tasks to Firefox, each using about 4 k of memory.
After about a minute, the additional tasks of Firefox (the 4 k ones) start closing 1 by 1. I am now down to only 2 Firefox process, using 32 k and 4 k of memory, respectively. As far as I know, these processes will last forever, until I have shut them down manually. If I run Firefox again without closing the current process, it creates another 4 k process, which finally closes itself. If I close all the processes manually, I can start over from scratch. Meanwhile, Firefox never opens a window, or give a clue showing that it is running, with the exception of the processes listed in the Manager tasks.
I deleted the one in my USER folder without change. There are a couple more in various C:\Mozilla\Firefox\Profiles files, so I deleted those too, without change.
It's a custom location. Normally, the profiles are under AppData\Roaming, I think you already know. There is a shortcut:
This folder must contain a profiles.ini file (.ini file extension may be hidden), which shows the names and paths to your profile folder (s). If you check in a text editor such as Notepad, this file contains sound data?
If this started right after an update, it could be a problem with security software, put an end to the commissioning (rules of program control) or program files has been corrupted.
You can check your firewall and other security software for program restrictions.
To meet possible corrupt files, I suggest:
Clean reinstall it
We use this name, but it isn't about deleting your settings, this is to ensure that the program, files are clean (no incompatible or exotic code files). As described below, this process does not disrupt your existing settings. Don't uninstall NOT Firefox, that does not need.
(A) download a fresh Installer for Firefox 43.0 https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).
(B) the release of Firefox (if any).
(C) to rename the folder of the program as follows:
(Windows 64-bit folder names)
C:\Program Files (x86)\Mozilla Firefox
C:\Program Files (x86)\OldFirefox
(Windows 32-bit folder names)
C:\Program Files\Mozilla Firefox
(D) to run the installation program that you downloaded in step (A). It should automatically connect to your existing settings.
A cleanly reinstalled Firefox starts up normally?
Note: Some plugins can only exist in this OldFirefox file. If it is missing something essential, present in these files:
Manager tasks shows Firefox loaded as a service, but a of threads waiting to complete. There is no application shown in the Task Manager (which seems reasonable that Firefox has not loaded).
There is no error message. The 'circle of rotation of microsoft"is going for a few seconds, then disappears as if the schedule.
It happens after 2nd & subsequent charges after reboot. Firefox seems to work the first time after reboot. It happened only after upgrade to 42. Clean installation makes no difference. Chrome works OK
Worked well up until the 42 update. Tried to do a clean install with the box to inform Mozilla erased.
Maybe Firefox started using a port that is blocked by the antivirus? I don't get no logging for the virus scanner showing what it to be blocked. A comprehensive analysis reveals nothing.
Operating system is Windows 10 (64-bit)
Abandoned trying to actually find what is actually happening. Changed software virus scanner.
I think (and this is just a guess) is that to integrate with windows update update 42 change the output method to the telemetry file the antivirus does not. It is perhaps that the antivirus cannot manage that file or property, but it does not record the fact, a failure of the antivirus.
There is a hint of doubt in my mind when an upgrade causes a system that works to fail in a non traceable method.
When you go to many websites, including N4G.com and Royalroadl.com, my browser will slow down suddenly, and container plugin firefox will Flash quickly on and off tension in my task manager, too fast to turn it off manually.
The only way to solve this problem, so far, has been to stop the page from loading before a certain point.
This also prevents many videos loading and the major slowdown. He has only started to happen after I have updated to the latest version of Firefox, and disabling all plug-ins and extensions did not resolve the issue.
My current version is 40.0.3.
Someone knows how to easily return to the most recent version without problems?
Edit: Both, I found the solution!
I went into the plug-ins for Firefox, went into the menu Options for the Shockwave Flash plug-in and disabled Protected Mode.
For some stupid reason, Protected Mode was the thing causing videos blocked and slowdown.
Spread this solution for anyone with similar problems, please!
We have about 5 users having Firefox refuses to open. In the task manager the firefox.exe is running. When we run as administrator, it works sometimes, but runs faster. We tried the ESR 38.2 Firefox and that worked for a day or two. I deleted their profiles and installed Firefox fresh with no Add-ons, even a day or two later, it opens. We turned off hardware acceleration, no change. The only thing I can think that I have not done is to clean the registry.
5 users = all on the same PC?
Or what with workstations and profiles on a server?
Any type of configuration customized for when Installer Firefox?
See if anything here helps you:
usually in the earlier version as 28, so I end the process "firefox.exe" task manager and run back the firefox, it will restore the tabs normally I opened (websites that I had until I stop the firefox.exe)
But now that more recent versions, not give me this feature, restore session screen becomes white and I drop my open sessions.
I have to use the history to restore the sessions that I lost,
Please can someone take a look at this problem, it would be an interesting option to stop the firefox.exe in the Manager of tasks and able to restore all the sessions again
I have attached a picture for your information
Unfortunately the image have no download, but there are built in the back of the inverter session. If these do not work correctly, we are happy to investigate.
However, there is an addon that helps with backups called session manager Session.
It is a continuation of a thread found here:
https://support.mozilla.org/en-US/questions/997448 by Compumind.
I pointed out that I had the same experience, especially at the opening of the email links in Thunderbird. I reported also that forced me to go back to 28 FF.
Moses responded by top wire and suggested:
(1) download a fresh installer of https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).
(2) the release of Firefox.
(3) rename the folder
C:\Program Files (x 86) \Mozilla Firefox
C:\Program Files (x 86) \OldFirefox
(4) run the installer you downloaded in the #1. It should automatically connect to your existing settings.
I followed these instructions carefully but no joy. When installing 29 FF, not only refused to leave (using "exit") and continue to run in the Task Manager up until I killed him after the opening of links in Thunderbird, but I find that he refused to come out after a simple navigation and links.
Moses had asked that I didn't answer in the original thread, so I re-post here.
In my view, that there is a serious bug. With Firefox 28... no problem don't except a minor that I have indicated here:
Yet once I am obliged to 28 FF, although I miss the nice interface and security patches, I need to have a browser that works properly. My wife never even saw the Manager of the tasks before so that's the problem.
In addition, "guesses" made with this post, the only other thing usual outside that I do, is to have a security policy about cookies (accept by default... I make exceptions for cookies I want to keep and have several that are "allow only for the session.") I also FF the value delete history of navigation at the exit, but that takes a fraction of a second.
I look forward to when this matter can be addressed successfully and I am able to use 29 FF (and out properly... I can't wait for my wife to follow all of these instructions and it often close manually in the Manager of tasks... or what I want to do this.)
Good luck for all Mozilla projects. Having installed 29 FF twice and then back return 28 twice, I'll wait and see how this plays out. Please don't send me the standard "start in safe mode", 'restart with disabled modules', 'reset Firefox' stuff (the last time that completely destroyed my browser). I don't think that is what is happening.
Moses added that there is a problem with the e-mail notifications passing by, so take your time, friends.
I think now (temporarily) this bug or problem has its roots in "history leaving Compensation."
I made the leap after a few game with 29 PortableFirefox and reading the blog post linked here:
.. .and installed 29 FF on my previous FF28 on my box. I unchecked the "clear history on exit" which was only to delete my history, not cookies or anything else, cor - el. My setting should not accept cookies unless I make an exception. Until the FF developers find a way to do this is functional, I'll just have to manually delete the history.
Furthermore, John99, you want to maybe privacy.sanitize.sanitizeOnShutdown set to 'False', not 'true' If you want to stop the automatic deletion of the history at the exit (attempt).
I've been running for about 6 hours. without experiencing the bug 'suspended '. So, I can live with that for now until this bug is fixed. It should be fixed... browsers are supposed to be able to do things like that.
On the other hand, I could find things go wrong... but so far I'm not having a problem.
I for several hours and will let you know later if things change.
After that restart of firefox does not start. is running in the Task Manager, but won't pop up. Reset safe mode and uninstall/reinstall won't help. OK so no reset.
Win7 Pro. has worked ok firefox. but lately with 25 and 26 now, firefox does not start. I see that firefox is running in the Task Manager. but it will not just appear.
If I still download and install it, it runs, but every time I restarted the system, it just does not work yet.
Reset try:, safe mode, uninstall & reinstall, new/clean profile none of these work.
I tried everything that was suggested before you guys and I hope that you have found a solution now. I tried to re install, allowing Firefox through my firewall and running it as an administrator. I always double click on the icon and nothing happens except the process in the Task Manager.
Create a new profile as a test to see if your profile is the source of the problems.
See "create a profile":
Profile backup and restore
tried to open Mozilla Firefox, but it is not appearing on my screen, the symbol does not appear in my start bar, and Manager tasks didn't pick up any sign of it. but when I tried to uninstall it, a pop-up explains how it works.

Firefox crashes whenever I open a site in flash like Youtube. If I open to the process task manager, then I see that flashplayerplugin will try and start over and over again and seems to hang over and over again. My Firefox and flash player are up to date. I tried to uninstall and reinstall firefox and flash player. I tried to turn off all the other modules. I even tried to install older versions of flash player, and nothing has worked. My wife uses Firefox to work, so is it possible to fix it?
You can check for problems with the latest version of the Flash plugin and try these:
- disable an eventual extension of the browser for Firefox Plugin RealPlayer Record and if installed RealPlayer update
- Disable protected mode in the plugin Flash (Flash 11.3 + on Windows Vista and later versions)
- turn off hardware acceleration in the Flash plugin
Alternatively, you can try to disable hardware acceleration in Firefox.
- Tools > Options > advanced > General > Browsing: "use hardware acceleration when available.
I have a laptop of 64-bit windows with Firefox 21.0 8. In the night I turn my computer off (not restart), I have fastboot or anything and when I login I run firefox and nothing happens. I can open Task Manager and find firefox and it says that it is using 178 k or an infinitely small number of memory, then state instead of saying 'running', he said 'suspended '.
I then finish that firefox and start a new one, and it works fine.
Why it does not the first time that I start it well?
- Update * - see the screenshots -
http://oi39.tinypic.com/33comrn.jpg this is what happens when I first try to start firefox after turning on my laptop.
http://oi43.tinypic.com/kn9dc.jpg this is what happens when I close Firefox which does not at the screenshot 1.
Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:
Note: You can print these steps or consult them in another browser.
- Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
- Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
- Remove the Firefox installation folder, which is located in one of these locations, by default:
- C:\Program Files\Mozilla Firefox
- C:\Program Files (x 86) \Mozilla Firefox
- Mac: Delete Firefox in the Applications folder.
- Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
- Now, go ahead and reinstall Firefox:
- Double-click on the downloaded Setup file and go through the steps in the installation wizard.
- Once the wizard is completed, click to open Firefox directly after clicking the Finish button.
Please report back to see if this helped you!
After update for drivers AMD 13.1 on my 5770, Firefox will not launch; It doesn't, however, appears in the Task Manager. I want to emphasize that it will boot into Windows safe mode; When I opened it in safe mode, I used this time to deactivate all plugins, modules, extensions and created a new profile. This did not help. I also tried launching Firefox in its safe mode and had no luck with that either.
I encountered this problem once before, when trying to upgrade to an earlier version. I think I was moving from 12.1 to 12.4, but I'm not 100% sure of that. In the end, my solution was then to retrograde back to my previous driver. The steps mentioned in the previous paragraph has not helped at that time, not do a complete reinstall.
experience of 15 years, and that computer repair baffled me.
Thanks to all those who might be able to help.

WIN7 (86). Cannot open FF. Download the message, that it is running, but it is not (not listed in Task Manager showing all processes). Tried to access my profile, but the search has failed.
Thanks, cor - el! The kb.../profiles.ini_file did the trick. I was able to find the file using %AppData%. Mozilla files were hidden. I have 'expose' them and presto, it works now! Thank you very much!
I used to get the Google search engine at the start of Firefox, with bookmarks bar in side bars and tool at the top. Now, all I get is a Google search page, with a few buttons on the top like images, etc. There is no way to close the program without using the Task Manager. I downloaded the latest version of Firefox and installed, but the problem has not disappeared. Operating system is Windows XP Professional
Make sure that you run not Firefox mode full screen (press F11 or Fn + F11 to toggle; Mac: Ctrl + Shift + F).
It is possible that the screen is too wide or too high and bars scrolling down.
- Use Restore or expand in the context menu of the taskbar icon to set the focus to the Firefox application if you do not see the window of Firefox.
- Open the system menu of the window of Firefox via Alt + space and see if you can move and resize the window (use the arrows on the keyboard).
If it works, then first close all other open windows of Firefox and then close Firefox via "file > exit/Quit" to save the setting.
If the above didn't help then see:
