Delete the processes. Press: CTRL, ALT, DEL at the same time. It opens your menu asking you different selections. Just click open task manager. Click the Processes tab and press F on ur keyboard. It goes directly to Firefox, you may also have to press M to go to Mozilla Firefox, depending on how it's worded on your programs. Click end process. Then just re-open. That is how you fix it that time. Use the links on the last post about hanging to fix Firefox and learn more about hanging.

    I usually have 3-4 tabs open which I am saving to read later. But I loose them all the time when firefox crashes or when another appliaction opens firefox to download something and it will discard all my tabs. This is incredibly annoying, is there a way to save my tabs ? or get them back when there is no "restore session" button ?

    In Firefox Options / Privacy be sure "Remember download history" is checked. To see all of the options on that panel, "Firefox will" must be set to "Use custom settings for history".

  • Firefox is OPEN and working fine, but when I click a link in Thunderbird I get 'Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.'

    If I click a link on my desktop or in any other program (while Firefox is open and running), I get this message: "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." There's about a billion links for this if you Google it, but they all say that Firefox wasn't shut down properly. (OK, maybe not ALL of them, but if the needle is in that haystack, I haven't yet found it.) That's not the issue in my case since I haven't shut FF down at all.

    Hi Andis.
    First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
    To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
    Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
    Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
    https://addons.mozilla.org/en-US/firefox/addon/3559/
    Hopefully this will help.

  • Foxfire stays in back gro I get this script when I try to get back on Foxfire after closing it. Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart.

    This happens 95% of the time when I close Foxfire and then later try to get back on. I usually have to restart my computer before getting back on to Foxfire.

  • Doesn't start when starting as administrator. Error Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

    Update firefox, it asked me to update flash, I tried to update flash but it said I had to close firefox. A box came up and said the Flash install would continue when I closed firefox. I closed all firefox windows and no update of flash occurred. I tried relaunching firefox but got the "Doesn't start when starting as administrator. Error Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." message. I rebooted the system, no improvement. I tried to run firefox as administrator and got the same message. Either I find a fix or I won't be able to use firefox and will have to go back to ie.

  • When I try to access Firefox I get this message: "Firefox is already running, but is not responding. To open a new windwo, you must first close the existing Firefox process, or restart your computer."

    When I click on Firefox I get a window that says: "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your computer." I can't see where anything is running on firefox. I restarted the comuter and I shut down the computer. I also ran a full scan of the computer.

    Sorry I am a PC user but have you seen
    * [[Firefox is already running but is not responding]]
    Firefox will be hanging for some reason. The quick solutions to kill the process and try again. The next step is to try to see if it will start and exit normally a couple of times, if so the problem is solved. If not the reason needs further investigation.
    See [[firefox hangs]]
    An immediate likely culprit after repeated problems are the duplicate session restore files, as discussed in the above KB article.

  • I want it to ask the master password all the time when I open the site which my password is saved

    I want it to ask the master password all the time when I open the site which my password is saved.
    This is not the problem, may be a feature.

    Your question is quite vague, but if I am right then, go to Tools> Options and then "Security" Tab then select "Saved Passwords" and you should find all the passwords you have saved for websites so far. If its an issue with the master passwords that is for Firefox itself, then the Master Passwords option is right above this. Have a look at the image below.

  • Should I run Firefox with Rosetta all the time?

    I was just wondering if it's a good idea to run Firefox with Rosetta all the time or will the browser run faster if I turn it off when it's not needed?
    I need to turn it on enough to make me think it'll be easier for me if I leave it on all the time.

    It will run faster and use less memory if you let it run natively- whether the loss in speed is made by the convenience of not having to switch it (for whatever reason you're switching) is a personal calculation.

    somehow i couldn't get rid of one website called www.searchqu.com/405 set as my homepage... I tried all solutions given to change the homepage but whenever i restarted firefox that homepage used to come automatically.. So, I deleted the profile (even from recycle bin!!) and deleted the firefox and downloaded it again hoping to get my problems fixed (which didn't happen!) because i'm getting dialog box saying- Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

    You don't say which operating system you have installed?
    Assuming it's Windows, right click a blank part of the Windows Taskbar and go to Task Manager. Then click the ''Processes ''tab, find '''firefox.exe''' and then right click it and choose '''End Process'''.
