Firefox 4 will not open google chat - it works on Google!

I cannot use Google chat with the latest download of Firefox. Google chat works perfectly when I use the Google browser.

I had this problem as well, but was able to solve it using this procedure:
- Close firefox from the menu (don't use the 'x' as firefox may continue to run in memory for a while)
- in your start menu, enter the following into the "run" prompt: firefox.exe -P
- The firefox profile manager will open (see attached image)
- In my case I deleted the "default" profile because I didn't care about losing any settings. You may want to simply create a new profile instead in case you need to save your settings.
- To avoid being asked about which profile to be used you can highlight your new profile and then make sure the "Don't ask at startup" checkbox. When ready, press the "Start Firefox" button.
- Voila! That fixed it for me. Like I said, I just created a new "default" profile and everyone worked fine for me; use your own judgement here.
Good luck!

  • Firefox will not open Bloomberg radio..works with IE

    After downloading Firefox I have not been able to open up Bloomberg Radio from the Bloomberg website. Other radio audio operate, but not bloomberg. I can still use IE to listen, but not Firefox.

  • Firefox will not open on my computer the majority of the time. If I shut down and restart it will work sometimes, but not always. This started recently in the last two weeks. Today is June 12th 2011.

  • 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 unless I run it in compatibility mode (Windows XP SP 3), run it as an administrator, or launch it immediately after a reinstall (the reinstall thing only works once.) How do I fix this?

    This morning, Firefox crashed. After this, when I click the Firefox icon, the hourglass appears and then nothing happens. Firefox does briefly appear in the task manager when I do this.
    I tried rebooting. I tried reinstalling multiple times. (Firefox will run when I select "Launch Firefox" from the installer. Then the problem occurs again.) I tried safe mode. I have found that Firefox will work if I select Windows XP compatibility mode from the icon properties menu or if I run the program as an administrator. When I do this, Windows asks me if I want a program to be able to make changes to my computer.
    I have noticed that a Windows Error Report is being generated each time Firefox will not open.

    A possible cause is security software (firewall,anti-virus) 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.

  • Firefox will not open at all. Google Chrome main browser.

    Google Chrome my main web browser with Comcast as home page.
    Now Firefox will not open at all. What do I do. Delete Firefox and reinstall is what I think?

    Yes, i would try reinstalling Firefox first.
    A few other basic trouble shooting things you can try is this:
    Run all Windows Updates, install all needed service packs, etc.
    Update your graphics driver (Firefox uses your graphics card for some rendering, and an out of date graphics card driver can cause problems. [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
    Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
    Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. You can uninstall this program after you clean off any infections.

  • I have no navigation bar and firefox will not open in safe mode to reset to default config. Reinstalling doesn't work. Any help please.

    I have no navigation bar ever since I closed it to gain more space on the screen. It won't re-open. Firefox will not open in safe mode, but opens immediately in normal mode with the new improper config, so I cannot reset to default config. I erased Firefox and re-installed and it still opens with the same faulty config. Why does Firefox not give me the safe mode dialog box, why can I not re-open the nav bar, and how can I do these two things, please? Firefox is currently unusable for me without a nav bar and without access to the default settings in safe mode. I cannot research the extensions I'm running since I have no nav bar to go to Tools, Add-ons, Extensions.

    Hit the '''Alt''' key to show the Menu bar, then open View > Toolbars and select Menu bar and Navigation bar, so they have a check-mark.

  • Simply stated, firefox no longer works for my husband. Firefox will not open when my husband is user.

    As a user, firefox will open for me. As a user, firefox will not open for my husband. Yesterday McAfee had to remotely turn the McAfee firewall back on. I don't know if during this process it somehow affected firefox.

    Hi DoesFirefoxRespond,
    Thank you for your questions. I understand that there is an issue with accessing some bank sites. If you have already disabled Firefox add ons and have still experienced the same issue, please try the following:
    # Open a Private Window and login to the bank site to see if it causes the same issue. It will not use active logins or previous history.
    # [[How to clear the Firefox cache]]
    Please post back with your results, we are happy to help.

  • 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.

    I resolved the problem. I went to CNet and re-downloaded the upgrade. It proceeded as intended and the upgrade is installed and running with no loss of plug-ins, bookmarks, etc.

  • 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.

  • Firefox will not open after attempting to upgrade to v5, sys restore didn't help

    Was running 3.6 with no problems, but trying to upgrade today apparently broke it. The upgrade failed for some reason (the old .exe is still the only one in the Firefox folder & I can't find any files newer than April 2010 in there), but no matter how I try to run it, nothing happens - Firefox will not open, period. I tried reverting to last week with sys restore, scanning for malware with Malwarebytes, but still nothing happens. I'm using WinXP 5.1 media edition SP2 (yes, it's been around a few years but it works for me). I'm now using Chrome which seems to run just fine, tho I miss all my plugins.

    Hi lwhealon
    try from Start > Run > and type to check 1 of :
    firefox -safe-mode
    "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode '''or'''
    "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -safe-mode
    (to enable the Run box in win 7 see: [http://blogs.msdn.com/b/tims/archive/2006/09/18/windows-vista-secret-3-bringing-back-start-run.aspx enable Run box win 7] )
    also check if [http://kb.mozillazine.org/Firewalls Firewall] or/and other security software blocking firefox start (like ad-blocker, web-accelerator etc).
    [http://kb.mozillazine.org/Kill_application With Firefox completely closed] (probably because you can not start it), open the [http://kb.mozillazine.org/Installation_directory application folder] (by default, C:\Program Files\Mozilla Firefox on Windows) rename firefox.exe to firefox1.exe, then double-click firefox1.exe. If Firefox runs without problems, it could indicate that your firewall is blocking Firefox.
    good luck

  • Firefox will not open now - I just updated my privacy settings, and cleared cookies - what happened?

    I changed the privacy settings on Firefox preferences, including clearing cookies, history and cache, and now Firefox will not open at all. It said it had to restart after one of the privacy changes, but it didn't and now won't open by the dock icon or thru applications. What happened, and how can I correct the issue to start using Firefox again? Thanks.

  • Firefox will not open after unlocking Sempron

    After upgrading to a new motherboard and unlocking Sempron processor, Firefox will not open. I have tried Firefox (safe mode) and rolled back to a previous version, but to no avail. It worked fine when I ran the Sempron 140 as a single core (even overclocked to 3.17ghz) on Biostar A785GE motherboard. I cannot find a crash ID to link to.

    Maybe you restored to a version of Firefox that crashes or still have a virus problem.
    (irrc some Firefox versions specifically had problems after Windows restores)
    Follow up checking for malware and then try re-installing Firefox. I would also suggest you make a copy of your [[profiles|profile]] including all folders and sub files and put it somewhere safe as it may assist in restoring your bookmarks and information.
