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.

  • Firefox won't close. When I shut it down, the window closes, but I can't reopen it. I get a message that it is still running. When I shut down my PC, I get a message that Windows can't shut down Firefox.

    The question pretty much details my problem. I have to force a shutdown of Firefox and reboot to be able to browse again.

    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.

  • Since Firefox8, every time I start it, it opens 2 extra tabs to tell me that Firefox is installed, and that dwhelper has been updated. These changes are not new. Also, when I open a bookmarked site, the previously open site remains open.

  • Firefox crashes when I load any youtube video on the latest version, it not only crashes firefox but my whole computer goes blank and I have to restart, why is this?

    Backstory: There are two possible events that could be causing this
    1: At some point I may have followed a ''Tinyurl' link that consquently lead me to a youtube video, to which youtube worked perfectly fine before hand, and this is where i witnessed the first crash. Theories into whether this link, previously stated, may have done something to my system have been thought about, but the fact that youtube still works on the latest Microsoft Internet Explorer seems to present the idea of a virus or an error redundant. I own the latest Macfee antivirus software and Ccleaner(running the registry check) and have run them complete with disc defragment and scan disc error recovery along with an additional malware scanner. Nothing seems to have come up on anything. After doing all this, my last resort was System restore and this seemed to solve the problem, mainly because i had an earlier version of firefox. therefore i resisted updating for aslong as possible whenever it told me to update. but the otherday i thought i'd risk it again thinking it may have been a problem alot of people have been having and it would of been fixed, but sadly it hasn't. this lead me to google the problem and was advised to start firefox on 'safe mode' as there may have been a confliction between add ons or plugins with youtube or some thing like that, but sadly that hasn't worked either. The plugins i had installed with it were the ones firefox has told me to get, or recommended and the only two addons i had on firefox was Adblock plus (fanboy subscrip) and Noscript.
    Details of what actually happens: go to a youtube link, video loads for about 2 seconds(both video and audio), screen freezes, and flashes maybe once with some small lines across the bottom half of the screen horizontally towards the right corner, then the screen goes blank and makes my laptop dorment, but still running, thus I restart my system.
    Sadly now when I system restore there isn't a point far back enough before this problem. So its either i downgrade(which seems to be the only option) or simply stop using firefox, as internet explorer works perfectly fine. however running firefox with no scrip and adblock plus is the ideal browser customisation, which is why this is rather annoying.
    so number 1 was the tinyurl theory and i must admit i was abit foolish to follow such a random link, but whats happened has happened.
    2: basically there is a major disfunction with the latest firefox that has to with the addons i have included onto firefox and this seems to be causing a terrible effect on my system.
    in a nutshell: firefox worked perfectly before upgrading to the new firefox and before i followed this link, the rest of my system is completely normal and virus and error free or so it says, Other browsers seem to work also. safe mode does not cure the problem.
    Running on a customised Dell laptop, which is pretty midrange-toprange and hasn't been active long, so it has the general HD video card thats included in all Studio 15 Dell laptops.
    any help appreciated.
    cheers.

    I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
    When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
    At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
    I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

  • When I close firefox it closes but then when I try to open another session my computer tells me that firefox is still running and I have to restart me computer to get it to work again.

    The message that pops up when I try to open firefox again is something like, "Firefox is already running but not responding, please close Firefox or restart your computer before opening a new session."

    I close firefox and when I try to open it later, a pop-up says it is still running and I have to restart my pc? tried closing Firefox down but Task manager says it is NOT running even though the window that pops up says it is still running??

    When you go to task manager, go to the "processes" tab, right click on "firefox.exe," and select "end process tree." In the picture I've attached, I'm using windows 8, so the UI is a little different, but I hope it points you in the right direction.

Especially what it says under "File type" - it should be "Program"; if it's not, we'll have to look into what the problem could be here.
    Slightly off-topic, your Internet Explorer seems to be quite a bit out of date (IE 6, where current version is IE 8), so I would strongly recommend that you try to run Windows Update to get your system updated. If this is a company system (like a Terminal Server thin client machine), this may not be possible, and your system administrator will most likely have to help you.

    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.

    Back up all data.
    Triple-click the line of text below to select it, the copy the selected text to the Clipboard (command-C):
    /Library/Internet Plug-ins
    In the Finder, select
    Go ▹ Go to Folder
    from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
    From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
    The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present.
    If you still have the issue, repeat with this line:
    ~/Library/Internet Plug-ins
    If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.
