Firefox will not start up. I have tried many suggestions from your website and am now wondering if I should uninstall/reinstall? I have to use IE and am not happy about that..

When I try to start Firefox it shows the little spinning circle for a few seconds and then nothing. It will not open now no matter how I try.

  • Firefox will not display characters that were added by the webmaster on user PC?

    I employed a company to design a site for me which is great. Then I asked them to add a small button/image in the back end (admin area) that when clicked on will send an email. No image will display so I got them to change it to Text format, still it is not showing on my end. The design company are able to send me emails showing where it is but I cannot see it. It is worthwhile mentioning that it will not display in either IE8 or Opera, Is it a firewall problem ? Or a setting on Windows 7?

  • Firefox has recently started locking up whenever I try to open some websites, and it then starts to hog computer resources by going up to use 50-60% of my CPU where it typically uses 5-15%.

    I have had issues within the last three weeks or so where Firefox will lock up when accessing websites like deviantArt.com or Facebook, and sometimes even Google searches. When trying to load these sites, sometimes the program locks up and starts using 50-60% of my CPU and sometimes a steadily increasing amount of RAM. The only way I can fix it is to go into Task Manager and kill the program, then restart Firefox. This isn't always a fix, either, as sometimes the same exact problem immediately occurs when I reload Firefox and have to kill it again through TM. I typically have four to six tabs open, and have never had issues with Firefox like this before the approximate date of the 17th of September. Could this issue have been caused in the more recent updates?

    try this:
    For me the solution was the network.http.max-connections setting. Lowering this setting from it's default of 256 to 32 fixed the issue. If you haven't tried changing this maybe give it a go by typing about:config into your address bar, then click on the network.http.max-connections setting and changing the value to 32.

  • Firefox will not open windows that are linked on a site, for example reviewing a piece of work that has a link which opens it in a new window.

    There are links on site that open in new windows and close after you are done. Like A review link/box. The window opens but it's a blank page and the url books just says "search bookmarks and history".

  • Firefox will not open after I've had viruses on my computer

    I had been using firefox and have TONS of very important passwords and bookmarks saved on there. I got a lot of spyware and viruses all of a sudden and firefox stopped opening. I have had to use internet explorer in it's place and am not happy about that at all. I have since hopefully removed everything from my pc and now have virus protection. I have uninstalled and reinstalled firefox twice but it still will not open when I click on it. PLEASE HELP! :)

    Use the [[profiles|Profile Manager]] to create a new profile. If the problem goes away, you can then [[Recovering important data from an old profile|move]] your bookmarks and other important settings into the new profile.

  • I upgraded from 3.6.13 to Beta 4.0 and now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing.

    I uninstalled Beta 4 and re-installed 3.6.13 now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing, I have been using Firefox for a long time but cannot resolve this problem can anyone help and give me a solution please. As I use Firefox as my web browser it is very frustrating.
    The fact it will not uninstall appears to be something completely new as nobody I know who uses Firefox has ever encountered this in the past.

    Did you check your security software (firewall)?
    A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

    Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
    Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

  • Tried to upgrade to osx 10.9 from 10.7 and I didn't notice that it downloads in the launcher. I turned my mac off and ever since then it has glitched out and will not download no matter what I do. I have had it for 3 years which is out of warranty.

    Tried to upgrade to osx 10.9 from 10.7 and I didn't notice that it downloads in the launcher. I turned my mac off and ever since then it has glitched out and will not download no matter what I do. I have had it for 3 years which is out of warranty. It now has a blank bar under the launch pad and no matter how many times I try re-downloading it or restarting my computer it does not work. I use too play starcraft and other games on this computer although new patched/updates have made it that I can no longer do that now. Really frustrating having to deal with this especially after buying this computer upfront and now out of warranty.

    Go to your Applications folder and find a file called "Install OS X Mavericks".  Send it to the trash and delete it.  Then try the download again.

  • I started working for ChaCha, and now firefox will not work unless I manually close it in the process tree every time I want to use it. I also cannot open more than 1 page at a time.

    I started working for ChaCha 11/26/2010, I had to download a program to take incoming questions.
    Ever since then, Firefox will not work correctly, even if I am totally logged out of ChaCha, and the page is closed, if I try to open my browser using Firefox, it will not open, I have to go into the processor tree and manually end Firefox, then it will work, but it will only let me open 1 page at a time. For example I have Firefox open now, but if I go and click on the icon to open it in a new browser, it will not open, I either have to close this, or use IE-I HATE IE lol.
    I cannot use the ChaCha add on you have because it is not for the new version of Firefox, please help, I love Firefox, but not being able to open more than one window/page at a time does not cut it, nor does having to manually stop it from processing. I have tried re-installing it too.
    Thank you, Melinda

    I should add that I face the same problem with Safari and Google Chrome.

  • Firefox will not start, after reboot.

    For a few months now Firefox will not start after I reboot my computer. In order to get it to start I click the exe then must go into task manager kill it, click the exe again, kill it again then, from there it will typically start, but sometimes it may take one or two more trys. When clicking the exe firefox will appear in the task manager under processes but will will start with ~7% CPU usage, then quickly drop to zero every time until it does actually open and start. I have ran a full system recovery and started anew after reinstalling mozilla several times failed to fix the problem. I run virus and spyware checks often and come up clean, and also run Chrome as a default browser.

    Hello Tom.
    You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
    Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
    If you want support for one of your add-ons, you'll need to contact its author.

  • After upgrading to 27, firefox will not start. Saw an error message during the upgrade process.

    After upgrading to 27, firefox will not start. Saw an error message during the upgrade process but cannot remember.
    Tried to run firefox.exe -P but receive error message:
    XML Parsing error: undefined entity
    Location: chrome://mozapps/content/profile/profileSelection.xul
    Line number 18, Column 1:
    <dialog
    ^
    Running on Windows XP SP3. No problem whatsoever before upgrading to 27. Sending this from Chrome as I cannot open Firefox at all.

    Thanks jschaer2000: after starting it once in safe mode, I closed Mozilla and tried several restarts in normal mode. So far, all worked:-)
    Thank you very much again.
    Still the automatic update process bothers me: it took me several days to discover the reason to the malfunction, since when I removed the problematic version from Add and Remove Programs, I didn't pay attention at first that it was another version, not v26 which I installed from my folder.
    In addition, I like to save the installation files before I run new programs and if I didn't have v26 exe file, I couldn't have operated Mozilla at all. Not that it was fun to remove and install again each time v27 didn't react, but it was better than nothing, I still prefer Mozilla over its competition.

  • Firefox will not start after computer restart

    Install Firefox, runs fine. Restart computer, Firefox will not start or finally when it tries to start script errors occur. If I reinstall Firefox after a computer restart, it will work fine, again when the computer is shut down the next time it is started, will not be able to use Firefox. Firefox will not start up in Firefox safe mode, will not start in windows safe mode. Not add on's, nothing added, just the Firefox installer Performed complete system restore on the computer, same problem. Windows 7 Pro. Remove Firefox from windows control panel, restart computer, install firefox, will run. turn off computer, turn on computer, firefox will not start or freezes. I am interfacing the internet via Explorer now.
    I have reinstalled Firefox so it will run in order to perform the steps requested below.

    Try this
    *https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions
    Open TaskManager, if it running '''firefox.exe''' > end all processes

  • Firefox will not start, even in Safe Mode. Evidence suggests that this is due to an incompatibility with the latest update of Java.

    Firefox will not start in WinXP. (I am sending this from an alternate browser.)
    I believe that this is due to some incompatibility with the latest update of Java. I believe that one of the tabs from my previous session included a Java application, and this is causing the difficulty. In recent days, since the last update of Java, I have had difficulty in loading linked pages with Java applications into Firefox, and have needed to switch to a different browser to do this.
    Now I cannot even start the browser, presumably due to the presence of a Java application on one of the restored tabs.
    When I now try to start Firefox, my ZoneAlarm security s/w presents the message "Java(TM) Quick Starter binary is trying to access the Internet." I click "Allow", but Firefox will not start. If I click "Deny", the same result. The same thing happens when I try to start Firefox in Safe Mode, I cannot even start Firefox in Safe mode.
    == This happened ==
    Every time Firefox opened
    == after recent update of Java

    You can try to disable the Java Quick starter and the Java Console extension in the Control Panel > Java.
    Control Panel > Java > Advanced tab > Miscellaneous >Java Quick Starter (disable)
    You can also disable the Java plugin in Firefox: Tools > Add-ons > Plugins
