A msg appears that Firefox is still operating and to close it. However it is not operating. What can I do? It does not show up on the Task Mgr window.

I had a crash of Firefox and since then I can not open it again. The msg appears that Firefox is already in use; however, I deleted Firefox from my system and tried to download a new version to no avail. I can not install the new version because I get a msg that Firefox is still running. I am using E IE for now and this is causing some problems. I would like to use Firefox but am not certain how to rectify this problem. Reboot did not solve the problem.

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.<br /><br />

You should not use IE6 (used to post your question), as it is riddled with security issues. You should upgrade to IE8 on your XP system.

    All you need to do is wait. While Firefox appears closed, it's not. It doing house cleaning. Cleaning out cookies and cache. How long it takes depends upon how much garbage you have collected.
    If you start the Task Manager and open the Process window, you will be able to see when Firefox has finished up and closed down.
    If you forced Firefox to close using the task manager, then the house keeping process seems to freeze up.
    Also, as you've already found out from the above link, some programs and plugins will prevent Firefox from closing properly. I've found this less common then simply being in a hurry. But you need to also consider it.

    Because Firefox sucks that way. I have the same problem. Royal pain in the @$$. I have to use the task manager to duck out of it, or you have to w8 & count to 10...lol. Stupid program.

  • I close Firefox session and then try to open a new browser window - get message that Firefox is still running and I need to shut down and restart. Need a solution

    I close a Firefox browser and at a later time want to open a new browser window but get message "Firefox is still running and I need to shut down before I can open a new session" I do not want to shut down as this is laborious - I can go into task manager and processes and click on Firefox and end session that way but this is not the solution. Firefox seems to be running in background but I cannot open a new session window without doing on of the above.

    Have a look at this post, see if it is of any help (though related to Vista, but same issue can be there with Window 7 also)

  • When I close firefox I can't open a window again. It tells me that firefox is still running and I have to restart my system. This is a recurring problem on a brand new system and very irritating.

    I don't know what other details I can give you. I am not very computer wise. Just an every day web browser and emailer. This is a catch 22 problem. For example when I am installing a program; adobe flash player for example, it tells me to close firefox to continue and when I do I get the firefox is still running message even though there is no window. And so the installation isn't completed. I like firefox but this is a bit of a dealbreaker. hope you can help.

    * Try this.
    * Type in the address bar about:config.
    * Accept the warning.
    * In the page that appears, in the Filter box, type network.http.max-connections.
    * Change the value to 32 (which is probably set to 256 in your case).
    * Close the about:config page.
    * Restart the browser.

  • My browser has been closed all night and in the morning I get an error saying that Firefox is still running and I need to shut it donw. Why is this?

    I close the browser and it does not matter how much time elapses it still says that Firefox is running. I am told to close Firefox before I can open another session. I hit ctrl+alt+del to pull the task manager and it does not show any Firefox applications.

    There is no '''5.1''' - Firefox 5.'''0'''.1 was a special version to fix some Mac OSX issues which Apple created with the 10.5 and 10.6 updates and the release of 10.7 Lion last week. Windows and Linux versions don't need those patches and weren't updated. The global download server array can't handle different version numbers for different OS platforms, so the full download versions had to be version number "bumped" for Windows & Linux to match the new Mac version number.
    As far as your support question, you probably had a "hung" Firefox '''Process''' - look in the '''Processes''' tab in the Task Manager. <br />

  • After I exit Firefox, I keep getting messages that Firefox is still running and I have restart my computer. How can I avoid this from happening?

    This happens when I close the internet browser. When i want to go back on, nearly every time, I get the message that firefox is till running, close or restart the computer. Since i have closed it, I continuously have to restart my computer (or switch over to Chrome)

    Sounds like it is hanging when you exit and later try to restart Firefox.

  • When I "Close" firefox and later try to reload I get a box stating it is still running and to close it. Well, there is nothing I can clik on to close it.

    After closing down firefox I may click on a URL to go to a web site and Instead of Firefox reloading I get a window stating it is still running and I have to close it down before it will reload. Well, there is nothing to close down......how do I fix this. It happens quite often and is very frustrating.
    I do not want to have to reboot my PC just to get firefox shut down.
    Larry

    Try holding control, alt and delete down in succession and then a dialogue box will appear with windows task manager. Once open click on the Processes Tab and look for firefox.exe. Highlight this and then click end process. It should come up with a warning but just click Yes. This should then close firefox and allow you to reopen it from your desktop without shutting down your computer. Hope this helps.

    Correct. When you did that, you voided all warranty/support, & forfeited the right to an out of warranty replacement.
    There was nothing wrong with the screen I bought,
    And, exactly, how do you know that? Since Apple DOES NOT sell iPhone parts, there is no official source for genuine parts. Thus, many on the market are counterfeit & produce nothing but problems.
    Good luck.

  • Sometimes when I close Firefox and then try to reopen, I get a message that "Firefox is still running" and suggests I close it (which I have already done) or restart my computer, what do I do?

    I really have had a problem with Firefox responding sluggishly for the last 6 months or so. I have difficulty opening it, closing it properly, freezing up. I don't have this problem with other programs, so don't know what is going on. Also I can't use my latest version....10 of Adobe Acrobat now. Dont know if that is my computers fault or Firefox. Any help will be appreciated.

  • It appears that Firefox affects my email by labelling most of my contact with "forget." How can we resolve this?

    Many of my contacts have not been able to reach me via email with the notice on returned mail that they have been blocked as "spam." This all started after updating Firefox about 30 days ago. I use RCN as my email program and having discussed this problem with them at length, their records do not show the word "forget" on my contact's address. Does anyone an answer to this problem.

    Firefox is only a browser. It has no controls like that. This may be an issue
    with your e-mail provider.

I have this about 3 times a day this past week but prior to that it was maybe every one or 2 weeks.
