Firefox does not open when clicking on the icon, the firefox.exe process consumes 99 % of the CPU and my computer runs slowly.

I have been a happy user of Firefox for many years. Around last April first I opened Firefox and was offered an update to v 4.42.0.0 which I accepted. Installation seemingly went well. I forget now exactly what happened but the result has been that ever since April 1 I haven’t been able to open the Firefox browser when clicking on the Firefox icon. My computer now was running very slowly. I tried to uninstall Firefox, but a popup told me I couldn’t because Firefox was in use. This confused me because I couldn’t see it being used. Only now I have found that on Task Manager processes that “firefox.exe” was consuming 99 % of the CPU. After removing firefox.exe by clicking End Process my computer ran better. I uninstalled Firefox I had on my computer and installed Firefox 5.0. Unfortunately I have the same problems: Firefox does not open when clicking on the icon, the firefox.exe process consumes 99 % of the CPU and my computer runs slowly.

Born2die! Brilliant. I am a desktop clicker and never knew Firefox had a safe mode.
Thank You!
I was unable to start in safe mode initially. The second time I disabled all of the Add-Ons and she started up just fine. I enabled them one by one hoping to track down the culprit but the problem seems to have gone away.
BTW I am running ver. 3.6.8 (in response to cor-el's earlier post) and
Firefox is in the process of downloading 3.6.10 (which I am starting to think may have been what caused this whole problem to begin with)
Incidentally, whats up with all of the Java Console Add Ons?
I have:
Java Console 6.0.11, Java Console 6.0.13, Java Console 6.0.15
Java Console 6.0.17, Java Console 6.0.20, and Java Console 6.0.21
What are they? Do I need them? Can I uninstall them? Is this due to using Open Office?
Also, .NET Framework 0.0.0 Should I uninstall it?

  • Firefox does not open when i click on the icon or menu path

    when i click on the desktop icon or go through the menu path to open firefox, the computer will run it but nothing appears. apparently, firefox is still running in the background but i cant get to it. so whenever i try to edit another program that involves firefox, i have to go to the task manager to manually shut it down.
    i tried running it in safemode but it does the same thing. furthermore, i deleted the whole program and reinstalled it hoping that that might fix the problem. however that did not work, i have searched all the offered support and have come up dry.
    i am running the current firefox version and i am using a windows 7 professional operating system

    Hi,
    It could be that a security software installed in the system is blocking the new updated Firefox executable. You may have to go into the settings of the security software to re-trust Firefox.
    Please also check if you are able to start Firefox by browsing to the Firefox installation folder ('''Program Files (x86)\Mozilla Firefox\''' or '''Program Files\Mozilla Firefox\''' ) and clicking '''firefox'''.

    My firefox does nothing at all.

    Also having the same problem.
    I have tried the following with no luck.
    *Uninstalling and deleting profile + profile.ini then reinstalling
    *deleting the .parentlock file

  • New tab does not open when clicking on + tab

    I'm trying to open a new tab. I click on the + tab and nothing happens

    Uninstall the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and Firefox that prevents new tabs from being opened.
    There are a couple of places to check for the Ask toolbar:
    * Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
    * Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

  • Firefox does not open links with a new window or tab for certain web sites, e.g. Santander On line banking, help links.

    When accessing some sites where they have links for additional information that would normally open a new window or tab, Firefox does not open either. This happens on a variety of sites, most recently the Santander on-line banking site.
    == URL of affected sites ==

    Such JavaScript links should show the image in the same tab, so make sure that you left click such links.

  • Book icon not opening when clicked

    I have an odd problem here.
    In my Contents tab on the left side, I have eight Book icons
    that, when clicked, open to reveal the Help topics inside them-
    just like any normal RoboHelp project would work. However, the very
    last Book icon in the list does not open when clicked. I checked
    the original file and all of the help topics are under the Book
    like they should be. When I compile the file and do a View Primary
    Layout, this last Book icon opens correctly. The problem only
    occurs once the project is built into the software I'm doing the
    Help for. When I move the Book icon up in the list (so it's not the
    last one anymore) it works correctly. But then the Book icon that
    becomes the last icon doesn't open when clicked. So whichever Book
    icon is last in the list doesn't open when clicked. Anyone have any
    clue what would cause this? Thanks alot.

    Hi Scott45 and welcome to the RH community.
    Have you tried deleting the book and adding it again? Also
    you can open the project's .HHC file in Notepad (or something
    similar) and check that the relevant TOC entry is displayed
    correctly there.

  • After upgrading to 3.6.4 (english) firefox does not open

    After upgrading to 3.6.4 (english) firefox does not open when I hit its button. I uninstalled it and reintalled it but the problem remains - My operating sys is VISTA 2 service pack. IE works
    Any suggestions?
    == Operating system ==
    VISTA 2 service pack

    I have been using Firefox on a regular basis for many years.
    I have two problems with Firefox 3.6.4.
    First, it keeps crashing....
    I have 4gb of memory on a Windows 7 - HP Laptop and whenever Firefox tries to allocate more than 1.5gb of memory it crashes. What is more interesting is the fact that while Firefox is running on a static page; such, as the google search page...the memory allocation keeps climbing... Even when nothing else is running.....Does anyone see a problem with this. I have tried all the suggestions that I could search for and I have come to one conclusion....the problem is software related and software problems should be fixed with software not by people manually going into an application and toggling something on or off. In other words the mozilla team should be looking at trying to resolve this issue.
    So, what programmer did you guys have write the 3.6.4 memory handler - a person who doesn't understand how to allocate and deallocate memory?
    Just so you know what I have been describing above about Firefox 3.6.4 is a memory leak, and memory leaks are usually a first sign of poorly written code.
    <u></u><u></u><u></u>==
    My Second Issue is in regards to the newest Firefox Update, which prevents me from going to the internet whenever it's installed because it has a flaw with its Network Proxy module. I have to re-install the original Firefox v3.6.4 to fix this problem.
    Solution:
    I'm going back to Internet Explorer because the mozilla team can't fix all these issues. I don't have the time to come up with a work around solutions for an inferior piece of software that is supposed to just allow me to browse the internet at anytime....
