Firefox will not open on my Mac - it always worked before

Firefox will not open today at all. It is sure, it is afflicted with Norton Firewall, Antivirus, etc. and I have MANY bookmarks. OS X 10.9.5. This is on Safari.

  • Firefox will not open any webpages, but other browsers work. How can I fix it?

    Firefox will not load any web pages. I recently ran a registry cleaner/virus scan on my computer and now Firefox 5 will not load ''any''webpages. It displays a "Problems Loading Page" error message. Other browsers still work. I tried uninstalling and re-installing firefox, even restoring to a previous restore point, but nothing seems to work. How can I fix this?

  • Firefox will not open on my mac; crashes whole system when I try to open!

    Firefox crashes my whole system when opening for my Mac 10.5.8

    Unfortunately, Firefox 4 requires either MacOS X 10.5 or 10.6. For 10.4, you can run Firefox 3.6 from here:

  • Firefox will not open saved desktop bookmarks, it always defaults to home page, why is that?

    I like to launch Firefox by clicking on desktop shortcuts I have saved (bank, Netflix, Gmail, Amazon, Yahoo, eBay, etc...). With Firefox 29 any desktop shortcut now opens to my home page, Google. If I choose open to a blank page in the options, then all of my shortcuts open to a blank page.
    In Firefox 28 all of desktop shortcuts worked just fine. I like being able to start Firefox on a specific page. Now it looks like I can only open to my home page or a blank page. This is terrible!!! I have tried creating new desktop shortcuts from Firefox 29 and I get this same results. Really terrible.
    I can deal with the interface (which I really do not like now) but this simple lose of how I like to start Firefox is going to drive me away. Please fix or explain to me how I can launch Firefox from a shortcut and have it open that web page. Many thanks!

    Sorry didn't work. I am using MacOS 10.6. New shortcuts created in FF29 have the same problem. If FF29 is not open, clicking on the shortcut opens FF to my default home page, never to the shortcut URL I clicked. For example, clicking an Amazon.com shortcut I just dragged to the desktop, then quitting FF29 and clicking the shortcut launches FF29 to my Google home page. If I change my default browser to Safari all of my desktop shortcuts open Safari to the right page. Chrome had the same problem but I couldn't stand Chrome so I don't care. This is definitely a FF29 problem.
    I am really attached to FF in general and this is not a deal breaker, just a huge annoyance. Again, thanks for any help.

  • Firefox will not open on my Mac, it says something about security settings but I don't know where to go

    The button would be on your iPod version of Skype, not the computer version. They are not the same.

  • Itunes 11 will not open on my computer. It worked before I restarted it but doesn't work anymore.

    Itunes will no longer work on my computer since it upgraded to itunes 11.

    I'm having similar issue, but with Windows XP.
    I bought a new phone a few days ago and restored my itunes to it from icloud.
    Could the problem be related?

  • Replacing Firefox 3.6.16 containing my history, bookmarks etc by version 4.0, I find that it will not open on my Mac Power PC G4 running on OS 10.4.11. Is there is a compatibility problem and how do I retrieve version 3.6 with my bookmarks etc

    Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
    If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
    When you install one of the above it will use your existing bookmarks etc

  • Firefox will not open on my computer

    From sometime last night to today (11/18) Firefox will not open when I click on the shortcut link from my desktop. I've tried to add another profile by clicking on start/run/firefox.exe but that doesn't even work. What would be the next step?

    Do any error messages display when attempting to open Firefox?<br>
    In the task manager, is the <code>firefox.exe</code> process running?
    Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
    '''Note:''' You might want to print these steps or view them in another browser.
    #Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
    #After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
    #Delete the Firefox installation folder, which is located in one of these locations, by default:
    #*'''Windows:'''
    #**C:\Program Files\Mozilla Firefox
    #**C:\Program Files (x86)\Mozilla Firefox
    #*'''Mac:''' Delete Firefox from the Applications folder.
    #*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
    #Now, go ahead and reinstall Firefox:
    ##Double-click the downloaded installation file and go through the steps of the installation wizard.
    ##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

  • Firefox will not open...please help.

    My Mozilla Firefox will not open any windows, although it does start and show as running in my task manager. I have uninstalled and reinstalled it twice now and restarted my computer twice.
    I CANNOT start Firefox in safe mode by holding down shift or using the "firefox/safe" in the run box.
    I've tried it with applications closed, and open....I've tried it online and offline, I tried to run it in compatibility mode, I checked my computer for viruses...nothing helps.
    I have read every troubleshooting item here but they only say try safe mode, or do something from Firefox when it is open such as reset it. I have no add-ons or extensions on Firefox and it just worked yesterday...also my computer is brand new Windows 8.1 12GB ram 2TB harddrive and everything else works fine.
    please help

  • The firefox will not open new windows

    My firefox will not open new windows. It opens new tabs. The problem is in the windows.

    Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

    If it does work in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.

  • 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.

  • Firefox will not open ANY site. Wont work AT ALL. Nothing seems to be working.

    Firefox will not open ANY site. It worked last night, but not today. I uninstalled it many times, didn't worked. It displays the screen that says "unable to connect" yet chrome and explorer both work. I have disconnected and reconnected a few times, restarted my laptop, neither of those worked either. I have also tried turning "safe mode" off after re installing firefox, but again, that did not work. I need help :(.
    Although, before this, firefox was not letting me use voice recording sites or any site that let me watch television online. It would load the commercials, but not play the episode. It wouldn't even let me upload pictures to photobucket. However, it worked using chrome or explorer.

    Looks like a bunch of people have this problem. Anyone got any ideas to fix this???

  • Firefox will not open. Hangs at "connecting" stage. Non-responsive even to process shut-down via task manager.

    Starting yesterday, Firefox will not open at all. It hangs at the "connecting stage." For hours. It will not shut down even using the task manager for applications or processes, and it locks up virtually every other application. I thought I managed to save an open Word document yesterday - it looked like a slow, but normal save during the Firefox hang, but the document was empty when I restarted my computer.
    Even though my machine is not pentium 4 based, I tried starting using the Windows XP/M configuration, I downloaded and re-installed (over the top of) the existing version, I verified that no Mozilla processes were running before trying to start Mozilla, and tried creating a new profile. Absolutely no success. Every time (of the dozens) I have tried to start Firefox I have had to force a hard shut-down to get out of the application. I have now unpinned Firefox from my task bar because I keep forgetting and hitting it by reflex.
    I am running version 11.0 (at least that is what I just downloaded - I am not positive what I was running yesterday). My system is Windows 7 Home Premium, Intel Core i3, 2.4 gHz, 4 GB RAM, 64 bit OS.
    Next option is to restore to a previous version. If that doesn't work, I will uninstall and start over from scratch.

    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container 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 and the updater process.
