Ubuntu :: Firefox Error "firefox Is Already Running"
Jan 7, 2011
I've experienced the fairly annoying firefox error where it refuses to start the GUI. If there were no active firefox processes, nothing happened when I started it, but it did "start", meaning that I got the "firefox is already running" when I tried again. I found a fix to this, which was to delete some or all files in the ~/.mozilla/firefox directory. I now have 2 different problems. Number one is that the problem keeps reoccurring and I'd like to know what's causing it. The second problem is that even when I've "fixed" the issue, I still can't run firefox from scripts or click links. I get the "firefox is already running" error instead of a new tab or window.
i am wanting to use Firefox to connect to my smb shares. However, i keep getting this error message: Firefox doesn't know how to open this address, because the protocol (smb) isn't associated with any program. My client configuration is as follows: Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.1.8pre) Gecko/20100106 Ubuntu/9.10 (karmic) Shiretoko/3.5.8preI tried the instructions below to try and fix the problem with no success: Quote: From [URL]
Linux with Firefox In order to connect to a network share directly from you browser under Linux, you must configure Firefox to handle URL's starting with "smb://". This is done by typing "about:config" in the address line and hitting return. After that you must right-click the list of settings and choose "New -> Boolean" as shown below.
As name you must type: "network.protocol-handler.external.smb" with a value of "true". After that you must do the same thing over again, but this time choose "New -> String", type the name: "network.protocol-handler.app.smb" with a value of the path to the application you wish to use for browsing network shares. If you use KDE, this will typically be "/usr/bin/konqueror".
I am running F11 and I want to mount an FTP, but when I try to connect to an ftp server using Places -> Connect to Server, or the bookmarks I made I get an error that says 'Failed to execute child process "/usr/lib/firefox-3.5/firefox" (No such file or directory)' and sometimes it mounts anyway, but most the time it doesn't, and it never connects to the folder I asked it to, I just have to open the mount and navigate to it. I figure this happened because Firefox upgraded to 3.5.1 and the folder is now /usr/lib/firefox-3.5.1/firefox, but I don't know how to update this so that it looks in the right location.
Today I tried to start Firefox but, for no apparent reason, I got this message:
Code: 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.
I currently have 10.04 desktop version installed on my desktop. However my firefox seems to be running extremely slow. Can anyone guide me on the way of checking the system. Mostly is there a command that I can run that will kill all my unwanted processes. I do not do a whole lot on this desktop besides ssh and telnet to other devices and use firefox.
Firefox is running really slowly for me. It seems it's accessing the hard drive constantly (as seen through System Monitor).I'm running 10.04If I start Thunderbird and Firefox invariably the disk drive light just keeps flashing for minutes and the Firefox screen gets "grayed out" and everything just slows way down. Often I just throw the power switch to shut the computer off.
either install complete Desktop Environment like Gnome, KDE, Xfce or install Xorg only. Desktop Environments will install a lot of other packages too but xorg will install core packages necessary to run X Server only.
I'm going through the same problem as Tkeins. I recently loaded Ubuntu 10.10 Maverick server, further I loaded KDE also. So while I can run Konquerer from within the KDE, but not the firefox. Further when I try it from console I get the same message 'No Display specified.
I'm running Fedora 14 and I've just updated from Firefox 3.6.15 to Firefox 4 (rpm from remi repo). Overall, it's faster, sleek and running great on KDE . However, I've detected a minor issue. In order to run Firefox with a plugin installation free from nspluginwrapper (which seems to break partially when there is a major flash update), I switched from Firefox 3.6.15 64 bit to 32 bit and got the 32 bit versions of all the plugins. All was running mostly fine. When I upgraded to Firefox 4 32 bit, the two versions (32 and 64 bit) of xulrunner2 got installed somehow simultaneously. With the previous version, that didn't pose a problem. However, seeing as Firefox 4 is launched by xulrunner2, the 64 bit version takes precedence over the 32 bit one and consequently Firefox 4 32 bit is run as 64 bit app (?!) and no 32 bit plugins are loaded. By removing the 64 bit xulrunner2, everything is running as intended. Nevertheless, in the future, if xulrunner2 is used to run other XUL-based apps, as long as the 64 bit one is installed, it'll take precedence (in a 64 bit environment), which is fine, and anyone facing my situation will need to have a way to have both versions installed at the same time and specify that the 32 bit version should be used by firefox.
I have a 100% Slackware 13.37 network on both server and clients, with roaming profiles using NIS and NFS. Currently I'm debugging the whole thing, and I have a strange error that I can't quite explain.Sometimes when my girlfriend logs in, she gets some strange "Firefox is already running" error. The strange thing here is: ps aux | grep firefox returns absolutely no Firefox process. The only "solution" to convince Firefox to start again is to wipe her ~/.mozilla directory, but by doing this, she loses all her bookmarks and settings.
Just got the latest Updates which included Firefox 3.5.7I open FF on this machine and all I get is the attached imageWhen I try to expand it, all I get is a blank screen...I have updated 6 other machines without this issueI recall this happening one time before but I cannot recall the fix
I'm running Ultimate Edition 2.0 64bit. When I'm running Firefox and I'm not doing anything on it it starts to use the disk intensively. I checked on terminal using the top command and it IS Firefox using up to 85-90% of the resources. Anyone know what the problem is here? Can it be hacked? I already uninstalled and installed back again and it still doing it.
Firefox keeps freezing.the process keeps running.I've uninstalled firefox, installed different versions, ie 3.6, 3.7 etc, I've removed my profile folder in my home directory.same results. I've ran firefox as a SU and I get this output from the terminal
(firefox-bin:28892): GLib-WARNING **: g_set_prgname() called multiple times /home/josh/.gtkrc-2.0:2: error: scanner: unterminated string constant - e.g. `style' (parent won, so we're not deferring)
I just installed Apache2 and PHP on my computer but everytime I go to my localhost folder (ex: http://localhost/test/), firefox starts to download the index.php instead of running it. This doesn't happen in Chrome.
I'm running 10.10 FF 3.6.17 When I click on a link it doesn't go purple to identify that I have clicked it. I browse reddit alot so this is quite annoying. I searched google and ubuntu forums and can't find anything related to this so I'm posting this thread,
I have installed ubuntu 10.4 using virtual box (a tool similar to vmware). The problem is I m very familiar to firefox's window counterpart as the update is very simple. I have also observed that the preference part of firefox is under edit tab which is not in case of window's (Its under tools). How would I upgrade my firefox? Firefox version on ubuntu.:3.6.8 Firefox version on windows:3.6.3
How do i roll back firefox5beta to firefox4 and keep updating to the latest stable releases w/out upgrading to beta? The only extension that isn't working is FEBE which is incompatible w/ firefox5beta (profile, extension and preference backup). Have to use FEBE beta7 under Firefox4 so I don't think a compatible release for Firefox5beta is going to come out any time soon.
I recently upgraded (via Ubuntuzilla) to firefox 3.5.7 and now, every single time I close Firefox, the program seems to crash without quitting completely.
First, I receive an error saying that the program will not close and asks me if I want to Force Quite or Wait for it to close on its own. This has been happening ever since I upgraded to Karmic and if I just wait it usually quits fully after a couple seconds.
Now what happens is this: the window still closes, but if I try to reopen Firefox then I get this error stating that Firefox is already open and therefore cannot be opened again. The only way to get back into Firefox is to restart the entire computer. (Incidentally, this is the same problem that occurs whenever I try to Force Quit Firefox)
This now happens every single time I "close" Firefox.
Does anyone know the source of this error? Or a workaround?
How do I force Firefox to recognize a certain default firefox profile I have?
For whatever reason I can't get FF to show all of the add-ons I have. Yes, they are installed and they appear when as icons when I first boot up but after I close FF and start it again there are no icons (like Adblock).
Im using firefox version 3.6.12 and it functions fine. However when i use the latest version of this addon https://addons.mozilla.org/en-US/fir...11377/#reviews the screen goes grey and firefox crashes. Restarting firefox only results in more crashes. I had a older version of this addon-1.5 i believe that worked fine.
I create/modify web pages on Ubuntu and on Ubuntu it looks good but on Firefox that runs on Windows it is all messed up. The pictures or text is not as intended and that is really annoying. What is the issue here?I really don't understand.
More than often, my OpenSUSE 11.3 box completely freezes when surfing the internet with FireFox, forcing me to stop the computer the hard way (pushing the on/off button) and restart itDoes anyone encounter the same issue? Does anyone has a start of a clue to explain me why? Soes anyone could tell me where to start to look for the reason!Note that the last time the problem occues (i.e. 10min ago) was on this site (no other tab opened).My configurationSONY Vaio VPCF11S1E: Core i7 720QM, 6GB RamOpenSUSE 11.3 64bits. I did not install the official NVIDIA driver as it causes the screen fonts to be extremely bigOPenBox-session + tint2FireFox has the adobe flash plugin installed
I was really looking forward to Firefox 4, especially to trying the hardware acceleration. I'm using nvidia proprietary driver which is the combination which *should* work, according what I've read. However it doesn't. Firefox doesn't even recognize my graphics card, when I type about:support, there is no information about my graphics. So I wonder, is there anyone who got this working?
Following Problem:I am only using Linux at university, so I'm basically beginner. Today for some reason after logging in the the power of the computer went off.After restarting and logging in again I couldn't start my firefox (which was running before).Now I don't know whether it is because I'm still "logged in" with the old account (since logging in on several computers/terminals is no problem), or anything eitherrivial or a real problem...Is there any way to find out if I'm logged in on another terminal, and if how can I close this one (external log out possible)
I have 2 Linux systems - both running Fedora 14 and fully updated. They are sitting side by side on the same network. I have Firefox 3.6 installed on both, and running on one (call it system A). If I ssh to system B and run firefox there, I get a new window opened, but the browser is running on system A. If I close the instance of Firefox running on system A before trying to start one on System B, then the new window is actually running on system B.
This doesn't happen when I run Thunderbird on different systems. What is happening to Firefox that it performs this way?
I can't seem to be able to get Java working on my computer which is running Ubuntu 9.10 and firefox 3.6. I have followed instructions to download Java and when I restart firefox there is no Java plugin and it does not appear to be installed.
Has anyone else noticed that Firefox started running incredibly slowly?It just happened on two of my computers (one 9.10, the other 8.04 LTS).After starting firefox, it just sits and sits while trying to load a page. Even a local page (my router's config page). It literally takes about 5 minutes to load URL...Other internet apps are working fine, including Opera, which is how I'm writing this.
I am using Firefox and have done for a few years but just recently I find its running slow and this morning it crashed had to restart system FF is 3.5.9. What I want is what is a good un bloated browser Easy to use and Download helper can run on.
All day today, my laptop has been absurdly hot.The core temperatures were exceeding 70.0C even though it was on a cooling pad and I had disabled wireless, lowered the screen brightness, and put the CPU on Powersave. (For comparison, the temp usually stays at 45.0C if I do all this)
Finally, I decided to check htop, and I found IcedTea Plugin at the top with 99% CPU usage. This is used to run embedded Java applets (Java, not Javascript). Curiously, no Java applets were running at that time.Now skip ahead an hour to when I finally discover that the IcedTea Plugin was left over from earlier because it didn't stop running when it was supposed to. Looking online, I see several complaints about Java being very taxing on the CPU in Ubuntu, but I don't see anything about Java applets continuing to run after they're gone.
Can anyone who has Java installed confirm that this happens on their system?
1. Open htop. Search for "icedtea" to make sure it isn't already running. Then click on "CPU%" to sort the list. 2. Open this page in Firefox: www.java.com/en/download/help/testvm.xml 3. Check htop. Is IcedTea climbing to the top? (if you have Java, it likely will, because this is a common issue) 4. Navigate off of the Java.com page by closing the tab or clicking Back. 5. Here's what I want to know. Check htop again. Is IcedTea still there? 6. Restart Firefox to get rid of IcedTea.
