Can not make FF my default browser...When asked to make, I get "Your computer must be restarted to complete a previous upgrade of FF". After restart, it's the same thing all over again. I have explorer & chrome installed on my PC.
== This happened ==
Every time Firefox opened
== A few monts ago.

It is probably because you are not properly closing Firefox. Restarting your system would make sure that Firefox had terminated, but you do not have to do that.
To properly close Firefox on Windows systems, use
:File > Exit or "Firefox:" button > Exit
When you get the message "Firefox is already running" it is too late, and you must force termination of Firefox through the Windows Task Manager before restarting Firefox. Windows 7 has a keyboard shortcut to save you a step "Ctrl+Shift+Esc" then on "Processes" tab, select "firefox.exe" and use the "End Process" button. More thorough would be to right-click on the "firefox.exec" and choose "End Process Tree".
You would find firefox.exe in a Mozilla folder in your program files, but y0u would not want to delete it there, you would need to use the Control Panel which you have already identified and do it from there -- but generally you would not need to do that, and there is nothing in what you have posted to indicate that you should. But if you did do that, then don't let the install start Firefox for you as you would want to use you existing desktop icon or method of starting Firefox, and should decline having Firefox install start Firefox for you. When the install starts then invoke Firefox in your normal manner. This should eliminate problems of creating a new profile rather than using your old profile.

  • I can't uninstall/install FireFox due to a pop-up that says: Your computer must be restarted to complete a previous upgrade of Firefox..."

    This problem arose when I attempted to upgrade my existing FireFox browser to the new FireFox 7. I clicked through the auto-update, but didn't think that anything changed, as the browser didn't look like the image in the feature explanation image I was viewing. I then tried to download Firefox 7, and when I tried to instal it, this process began.
    I can't uninstall/install FireFox due to a pop-up that says: Your computer must be restarted to complete a previous upgrade of Firefox..." When restarted and attempted again, the same pop up appears and I am stuck in an infinite loop.
    I cannot locate the Mozilla file within my program files to try and delete cantankerous upgrade components, which seems to resolve this issue for many people. See: https://support.mozilla.com/en-US/questions/796566
    I also tried completely deleting Firefox, which didn't work either-- I ended up doing a system restore, only to be met with the same infinite loop.
    Now, when I click on the Mozilla icon, nothing happens. No window opens, no error message, nothing.
    Why can't I find the Mozilla folder in my Programs File but can see it in Control Panel "Add or Remove Programs" (though I can't uninstal due to infinite loop)?

  • After downloading an update, firefox says "your computer must be restarted to complete a previous upgrade of firefox. do you want to reboot now" and will not start.

    Firefox will not start, or allow windows xp to uninstall the program. When I attempt to start the program, firefox says "your computer must be restarted to complete a previous upgrade of firefox. do you want to reboot now? It gives the same message after rebooting, and will not start, or uninstall. I also downloaded it again, same thing.
    == This happened ==

    Just had this same problem. Based on other suggestions I found on the web, went to C:\Program Files\Mozilla Firefox and deleted all files that ended with upgrade and/or delete. Then I was able to uninstall Firefox and then reinstalled. Hope this helps!

  • Trying to upgrade from 3.6.18 to 5.0,b5. I am stopped from loading by message "Your computer must be restarted to complete a previous upgrade of FireFox". Reboot does not help. Can't uninstall 3.6.18. Get same message. Please help!

    A previous upgrade was not completed!
    Rebooting does not work.
    Can't even uninstall 3.6.18. Get the same '"must reboot'" message.

    If files already have been downloaded then you need to remove the files in the updates and updates\0 folder.
    You can delete active-update.xml and updates.xml as well if present.

    Vista:
    C:\Users\<user>\AppData\Local\Mozilla\Firefox\Mozilla Firefox\updates

    If there are problems with updating then best is to download the full version and uninstall the currently installed version.
    Download a fresh Firefox copy and save the file to the desktop.
    * Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
    * Uninstall your current Firefox version.
    * Do not remove personal data when you uninstall the current version.

  • In setup wizard it says "Your computer must be restarted to complete a previous uninstall. Do you want to reboot now?" after uninstalling old version and trying to install new. I CAN NOT run ANY version now......HELP

    I had an old version of Firefox and uninstalled it. Then I installed the 5.0 version. BUT, in the setup wizard it says "Your computer must be restarted to complete a previous uninstall of Firefox. Do you want to reboot now?" I choose "YES" and the computer reboots, but when I run the setup wizard again, it says the same thing. I have reinstalled it 8 times, and it says the same thing......I have searched my computer for it, and can't find what it's talking about!! HELP!!!!!!

    Thanks so much for your help, it is very much appreciated.

  • I get a message when trying to install firefox 3.6.10 that says "your computer must be restarted to complete a previous uninstall of Firefox." I have rebooted repeatedly, but still get this message. How can I get past this?

    I attempted to do the update on Firefox 3.6.9 and it said that it could not update because Firefox was still running even though it did not appear in the list of processes in the task manager. I decided to reinstall Firefox and the above message now is displayed each time I restart my computer and attempt to install Firefox 3.6.10.

    C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\xuab2q88.default is the location of the cache folder for your default profile. If the updates folder isn't there then it looks that Firefox hasn't downloaded an update.
    You can download the full version from http://www.mozilla.com/firefox/all.html
    Delete the Firefox program folder: C:\Program Files\Mozilla Firefox
    That will remove all Firefox program files in case some are locked or protected by security software.<br />
    That should allow you to install a full version of Firefox 3.6.10
    Your Firefox profile data is stored elsewhere and won't be affected.

  • After installing update, I repeatedly get message "your computer must be restarted to finish a previous upgrade," and I've restarted several times, and I when trying uninstall receive same message.

    Yesterday, I ran an update that was available. This morning when opening the browser, it stated that I needed to retsart my computer to complete the upgrade. I rebootted five times (at least) and it will not start Firefox. I tried uninstalling and planned to reload (apparently losing all of my favorites) and I can't do that--receive same message. I'm using IE today :(

    Run the Firefox program once as Administrator (right-click: Run as Administrator).
    If that doesn't help then do a clean reinstall.
    Download a fresh copy of Firefox ( http://www.mozilla.com/firefox/all.html ) and do a reinstall of Firefox on top of the current version. You won't lose your personal data like bookmarks doing that ([http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder]).
    See http://kb.mozillazine.org/Software_Update (Software Update not working properly)<br />
    You may need to remove the files in the updates and updates\0 folder:

  • When I tried to download the new version of firefox I get an error message that says "you computer must be restarted to complete an earlier upgrade" when I restart it says the same thing. I cannot use firefox at all at the moment.

    When I tried to download the new version of firefox I get an error message that says "your computer must be restarted to complete an earlier upgrade" when I restart it says the same thing. I cannot use firefox at all at the moment. When I try to uninstall in the control panel, the same message pops up.

    If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
    Download a new copy of the Firefox program and save the DMG file to the desktop

  • HT201263 ok, I did the above, and I waited 2 hours for this to download the "update." Then I try it again on the ipod, and it starts to redo the same download all over again !

    I started the update, and in the middle of it, the same previous screen pops up that it can't connect to the ipod,and the ipod screen goes back to "disabled." I waited it out, let the download finish. Then I had to try the process over again, and it started the download all over again, even though I just did that. Another two hours??? This is driving me mad. All for a stupid password ! How do I reset this dang thing, so I can open it. Bad enough I have to re do everything, because I have to restore it. PLEASE HELP !
    Just wanted to add that apparently the ipod is disconnecting and reconnecting to the computer somehow. I know because when you plug in the ipod, the computer makes a noise, as with any hardware. Well I click on "restore," agree to the restore, then it starts to download the update. A few minutes later, I hear the computer make the same noise, as if I have disconnected the ipod, even though I haven't even touched the cord. Then it makes the sound again, as being reconnected or plugged in, then the message pops up that it can't be connected, because a password has to be entered. The ipod screen then goes from the restore picture ( the itunes logo with usb cord) to the same "disabled, connect to itunes."
    I am not trying a different cord and seeing if that helps the plugged in portion.

    Do a manual install using the instructions here.
    have you download the update/firmware, place the iPod in recovery mode and then update/restore using the instructions in the article.
