Firefox cannot apply update

Every time I open Firefox it asks me to download an update. After the update is uploaded, it goes to applying it yet it never finishes doing so and then the whole thing starts again when I open the browser again. I've tried to run the update on safe mode (OS is Windows 8) yet it didn't work either.

Hello,
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.
Please report back to see if this helped you!
Thank you.

<b>WARNING:</b> Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These cannot be recovered unless they have been backed up to an external device!</u>

How can you configure Firefox to apply updates as soon as they are available?

I have a mandate to update Firefox across every machine in my enterprise within 48 hours of a new release. I have been doing this with intranet distribution tools (SCCM, etc.) but because of the frequency of Firefox updates this has become laborious.
I've been looking at the about:config settings in the "app.update" category (http://kb.mozillazine.org/Category:Preferences) and some of those seem promising. As a test, I set "app.update.silent" to TRUE and "app.update.interval" to 60 (seconds) on a legacy version of Firefox. I restarted the browser, let it sit for a few minutes then restarted it again expecting the latest update to apply, but nothing happened.
How can I script or automate via Firefox's internal settings the same update process that is triggered when users manually go to Help > About?

The Nightly versions have these values for some of the prefs because they can be updated daily more than once because of a respin
*app.update.interval : 7200
*app.update.promptWaitTime : 43200
You may need to reset update timer prefs.
*app.update.lastUpdateTime.background-update-timer
You can have a look at the comments in the source code that handles the updating process to see if that gives some ideas.

Firefox cannot be updated on 32bit pc

Can I stop Firefox telling me to use Setup 12.0
I cannot install on 32bit pc

I noticed you use some 3.xx version of firefox.
I had this problem on a pc of a friend, it wouldn't upgrade probably because of the version installed being too old.
Download the complete 12.0 setup of firefox here:
http://www.mozilla.org/en-US/firefox/all.html
Uninstall the installed version.
Then install 12.0 and it should work fine.
Hope this helps.

I have three user accounts on one computer. On only one account when I when I check Help - About fire fox only one user account says apply update and won't apply. The other two work fine.

One of three user accounts on the same computer appears to not be updating to 8.0.1 correctly. One admin and one none admin user account says it is up-to-date. The other non-admin user account, under Help About Firefox says apply update, but won't.

As long as you installed MS Office into its default location (the top level /Applications folder) it will be available to all user accounts on the Mac.
As far as licensing is concerned you only have to enter the license code once, which you should do right after installing MS Office, in the same admin account you installed it from, by opening any one of the MS Office applications. There is no additional licensing required for additional user accounts on the same Mac.
Each user account is able to run the Office apps. The only thing you will have to do is go through an initial setup screen in each user account (but this setup does NOT involve entering any additional license codes).
You may have problems if you installed MS Office in a particular user account (i.e. NOT in the top level /Applications folder).

Keeps coming up that I need to update the FF 4.0 but when I click the update button & then the apply update button after the download it doesn't apply & just come back up to update firefox

I have FireFox 4.0 it comes up and says that it needs to be updated, when I click the (NEXT) button & it does the contacting server/downloading the update. I click the apply update button & the fire fox window closes & the status bar come up with the installing the updates & will restart firefox in a moment. However once the window restarts, the notice that firefox needs to be updated come back. When I click the (next) button to download the update, the cycle begins.
I clicked the HELP link at the top of the window & then the ABOUT FIREFOX to see if there might be multiple updates, but it's the same one each time "modzilla firefox yahoo edition yahoo 1.8"
I love fire fox & until now have never had a problem when it comes to installing the updates.

Well I went to the Tools/options/and general section & clicked on the restore default for the home page. However I am still having the same issue.

Error message; cannot install update due to other Firefox versions installed. How do I checkfor other versions ?

Cannot install Firefox 7.0 update. Getting message that update cannot be completed. Check for other versions already installed. How do I look for other versions ?

Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0: http://www.mozilla.com/en-US/firefox/all.html
* Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Do not remove personal data if you uninstall the current version.
* 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.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program 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.

Many Thanks, Kurt.
I knew I'd seen the solution you've provided somewhere - either in MacWorld or MacFormat - but couldn't remember the Gatekeeper bit!
I shall save it somewhere VERY safe now in case this happens again …
You have made an old man very happy and saved me from worrying that senile decay had suddenly set in. (I was 70 last week so you might understand the situation from that.)

Firefox tries to install update then says cannot install update because you have to close another Firefox window, repeats every minute. Doesn't stop.

Update cannot install, says I must close any other Firefox window. (No other window open ) Cannot install update because another Firedox window is open.Since a recent update occured, You Tube videos flicker and browser favorites flicker. There is a flash card speed adjustment. The Flash Player and Firefox is not in sync.

Error: "FT DeepDark 11.3.1 could not be installed because Firefox cannot modify the needed file." What does this mean?

In an earlier version (Firefox v.31) on this, and (presently) on two other PC's, I was/am able to run add-on FT DeepDark 11.3.1 without any problems. It was only recently - after updating to v.32.0.3 on this PC that this situation started. The PC in question is a Dell Dimension 8400 Intel P4 running Windows 7, though I'm thinking it may have something to do with the newer version of Firefox. Could anyone help me with this? I like this add-on because it is easier in my eyes when browsing the internet. Thanks
PS: Attempted to install the troubleshooter, and again I received a similar error: "Troubleshooter could not be installed because Firefox cannot modify the needed file."

This error has been reported before in this bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=730040#c21
Please read that bug I linked you to and let me know if the last comment in the bug solves your problem. Apparently the problem is about the addon .xpi file being read-only. Try right-clicking it, going to Properties and unchecking the "Read-only" attribute box at the bottom of the dialog. Click Apply, then OK.
