I am running firefox 19.0 on Windows 7 64 bit. 3 times in the last 2 weeks i cannot open firefox. I have to uninstall it and reinstall each time.

I have run firefox for a couple of years on windows7 64 bit. Just bought a new lap top - still window 7 64 bit. Rep[repeatedly, firefox stops working (i can't open it). I uninstall and reinstall. I did that yesterday. It worked for about 24 hours - then I had to do it again.

'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "'Start in Safe Mode"''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''
'''''If it is good in the Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one.
Please follow the [[Troubleshooting extensions and themes]] article for that.
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''

  • I'm ready to drop Firefox because Scratchpad repeatedly opens anytime I have to Capitalize anything and at no time have I ever used the Web Developer tool

    Have used Firefox for many years on multiple computers. On the home desktop, anytime you need to CAP a letter, Scratchpad opens instead. Every single time!
    This is only having on this one computer, none of the others.
    I have completely uninstalled, cleaned and purged Firefox from this computer multiple times. I have run multiple virus checks. I have done the Firefox reset multiple upon multiple times.
    Yesterday I completely uninstalled every scrap related to Firefox I could find on the system, did a system clean to get rid of hidden and duplicate files, and with what I hoped was a clean system, reinstalled the latest version of FF. Same problem.
    WHY is Scratchpad coming up anytime I hit the Shift key?
    Somehow the developer tools and Scratchpad still show up and ultimately the problems start again.

    Hello Mark,
    I can understand your frustration with this issue - especially after you are running into this issue after resetting your computer too.
    Can you please check if the scratchpad comes up, if you disable the setting ''devtools.scratchpad.enabled'' by setting the value to false. You can do this by following the instructions in the Mozillazine about modifying the configuration of Mozilla [http://kb.mozillazine.org/About:config Editing About:Config]
    Thank you

  • Firefox is constantly hanging up my Macbook in the last week

    I have a white Macbook, purchased in mid 2009. For the last week or so, I'm having trouble with Firefox hanging up my computer so severely that only a hard boot (power off) will get it out of the spinning color wheel problem. I'm super frustrated and am even having trouble getting the computer to start up now. This ONLY happens with Firefox.

    Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See:
    * [[Troubleshooting extensions and themes]]
    This can also be a problem with the file places.sqlite that stores the bookmarks and the history.

  • I had a problem with firefox not showing up when I tried to open it. So I uninstalled it and reinstalled. After reinstallation my computer tells me the file is corrupt and I still can't open it. Other browsers work fine.

    Mozilla Firefox has worked fine for several years. Beginning two days ago I would click on the desktop icon, I would see the little whirling circle for about 1 second and then nothing would happen. Later when I shut down the computer, suddenly I would see the mozilla firefox page come up for an instant and then shut down. The computer was telling me that it was open, but I couldn't see the home page or use it. Then I decided to try uninstalling it and reinstalling. The uninstall went fine. But after downloading the latest version, which my antivirus program told me was safe, the computer refused to install the executable program, telling me it was corrupt. I have already lost all my bookmarks, etc. It looks like my only solution is to use another browser. However I really prefer Mozilla. Any suggestions?

    Do a clean (re)install and delete the Firefox program folder (C:\Program Files\Mozilla Firefox\).
    Download a fresh Firefox copy and save the file to the desktop.
    *Firefox 10.0.x: http://www.mozilla.org/en-US/firefox/all.html
    Uninstall your current Firefox version, if possible.
    *Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data because all profile folders will be removed.
    Remove the Firefox program folder before installing that newly downloaded 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.
    *http://kb.mozillazine.org/Uninstalling_Firefox
    Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

  • Firefox 7, on Windows 7. It's suddenly stopped all downloads, picture saves etc. I uninstalled it, and reinstalled it, but it's still the same. Any ideas as to what to do, please?

    I've now got Firefox 8 - so could, I guess, try installing that, instead. This problem happened quite suddenly, in the middle of a browsing session. I'm not so happy with the alternatives (Opera,IE and Chrome), and love Firefox, so would like to put this problem right! I'm using an Acer notebook One 722, by the way. Grateful for any help! Thanks!

    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 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.

  • Unable to update, deleted and reinstalled Itunes and my Pioneer DVR 218-L will not run. Install corrupted driver. Have tried to delete and reinstall 3 times 11.1.64 and not working?

    I recently attempted to " update " iTunes and received the missing .dll and Windows error message it seems everyone is posting. I had to delete  not only Itunes, but the Apple update and other associated file in order to get my Pioneer DVD DVR 218-L to work. The driver would not work and Microsoft had no fix for this. It told my registry was corrupt. Apple should certainly fix this problem. Now I cannot run iTunes at all unless I do not want a functioning DVD drive?

    I am having the same issue with Vista 64 bit: After many failed download attempts ("network error") the Progress Bar briefly appears and that's it.
    Searched for solution that led me to running "Microsoft FixIt", deinstalling iTunes, Apple Software Update, Mobile Dev Support, Bonjour, and Application Support - even manually deleting common files that were left over (tough with Vista). No difference. FYI, I was able to get rid of the Apple folder in Program Files (x86)/Common File, but not in Program Files/Common Files ... but that shouldn't make a difference as I am installing iTunes64Setup.exe, right?
    I even tried iTunes 10.7 and 10.6.3 from Apple's support page ... same differnce.
    Had a lot of security updates on 1/22/14 (all related to Office 2007 (including SP3), though). So I tried to restore past this point, but an "unknown error" occurred and I am stuck where I am ... lovely.
    So now my system is chopped and I seem to not be able to get iTunes even close to my computer ... :-(
    Just Irritatedtech said: Any suggestions are highly welcome ... - Thx.

  • Fox News is my home page, but firefox won't load it...for the last week. Works fine with MS Explorer. Ideas?

    About a week ago (15 Aug or so), Firefox began just waiting when I would launch it. My home page is Foxnews. If I wait long enough (minutes) it will tell me it is unavailable or moved and tries to offer alternate websites. I can go to any other website by selecting from history or typing in the url. When I launch explorer, it works without any problem at all. So, I've been using explorer. Today, 19 Aug, it is still doing the same thing. I haven't done anything recently. Running Vista Home for OS.

    Thanks for the suggestion.Working my way through, but no success yet. excite.com comes up but as soon as I click on "sign in", I get the error screen even though I have enabled cookies and java script.
    '''''The browser you're using is not allowing you to sign in to Excite.

  • I can't open anything that uses flash player in Firefox, I have uninstalled it and reinstalled it and no luck! but flash works fine on my seamonkey browser, can anyone please HELP me?

    None of the flash games will work on FF, I have even uninstalled FF and reinstalled it, I have disabled QuickTime, I have uninstalled Adobe flash and reinstalled it and still NOTHING! Flash works fine on Seamonkey though

    Check that plugin scanning is turned on (it should be by default). If it is turned off Firefox will not search the Windows registry for details of plugins that it can use.
    # Type '''about:config''' into the location bar and press enter
    # Accept the warning message that appears, you will be taken to a list of preferences
    # Locate the preference '''plugin.scan.plid.all''', if the value is set to '''false''', double-click on it to change it to '''true'''
    If it was set to false, re-start Firefox to see if the Flash plugin is now available.
    Also make sure that you have installed the version of Flash used by Firefox. You should have it because SeaMonkey is using it, but if the Flash plugin is in SeaMonkey's own plugins folder Firefox may not be able to see it.
    Download the latest plugin from http://get.adobe.com/flashplayer/completion/?installer=Flash_Player_10.2_for_Windows_-_Other_Browsers and run it to install the version of Flash used by Firefox, this will install it in the default location so that Firefox should be able to find it.

  • Since I installed Firefox 17.0.1, the program has become unstable. I have a hard time getting the program to respond to start. I have to try at least 3 times

    As I mentioned, the program will not start on the first time that I click the icon. The hourglass appears for a second or two and then disappears.
    I have to try at least 3 or more times before the program responds.
    Should I try to uninstall 17 and reinstall 16.
    I have already uninstalled 17 and reinstalled it.

    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 takes time loading and keeps stopping every few seconds, but only in the last week

    I have had updates for Windows and wonder if there is a clash between the two. I also seem to be getting more errors thn I ever had. I have tried uninstalling FF and reinstalling it and the results are still the same. It is damm annoying to have had such a great website that just seems to have malfunctioned overnight 25 April seems to have been the date, anything changed at your end

    hey try a smc reset
    EDIT (smc reset
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.)
    if that doesnt help look at replacing the batteries in your magic mouse and try it then
    if the issue still presists take it into a apple store and they can test it there to see whats up

  • I have an issue that I cannot open Firefox, and I get the message "Firefox is already running..." and it says I need to close it or restart my computer.

    There is a page on the support site that attempts to adress the issue...but it never says how to fix it. https://support.mozilla.com/en-US/kb/Firefox+is+already+running+but+is+not+responding
    Apparently there is a problem with the "profile", and on this support page, it has a link about working with the profile...if you go to that page, is tells you where the profile is, and the many things it does...but it does NOT say actually how to fix this problem. It tells you to go the the Help tab at the top of the browser, then select "Troubleshooting", and then under Profile, select "Open Containing folder"...which brings up the folder with all the files...but from there...it doesn't say what to do. I also have gone to the Start tab at the bottom of Windows (Windows XP--I've got Firefox 3.6.9) then Run and opened the profile box...but there are no instructions on what to do to fix the problem. I can open Firefox only by going to Crtl-Alt Delete and opening the process tab and ending the Firefox process...but this is not a fix. Help! thanks...

    You need "sysinternal's process explorer", it is free and can replace the Microsoft process explorer, that you get by "CTRL+ALT+DELETE". Either program will allow you to kill the instances of FF that didn't die as they should have, when you closed them. Sysinternal is easier to use, it is a graphic display with many options. Do not push "CTRL+ALT+DELETE" twice unless you want to reboot, that is its default behaviour under Microsoft.
