The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again.
Before I start Fire Fox I open the Task Manager to make sure no other copies of Fire Fox are running. When I click on the short cut there is a pause of about 1 second then this message appears. "The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again." I checked your FAQs where this problem showed up many times. I saw not solutions there. Where can I go to get an answer other than the usual remarks. Of course Fire Fox starts up immediately after the error message.
This happened
Every time Firefox opened

ahh thanks, tht was helpful :)
Nothing worked for me except downloading and installing over the existing installation. This was the case for both FF6 and TB6 on my win7 64 bit system.
I use Peppermint Linux with Firefox 4.0. Higher update versions of Firefox cause problems... then I disabled automatic updates.
Even with updates disabled in the advanced tools, I get this (...update could not be installed. Please...) identical window message pop up every time I start Firefox. Before the Firefox program will start, my Task bar will show the Firefox Icon with the word 'Update' on it and my Linux Task manager suddenly gets Firefox.bin. in it. I erased all 'update' hidden files in the Mozilla folder.
After killing the pop up by using the pop up window's X 4.0 will start or if I use Task manager to "kill" Firefox.bin, ("stop" will freeze my Peppermint program and I have to reboot) then the pop up window goes away. Once I kill the pop up window, Firefox 4.0 actually starts -- and all works fine. No updates ever actually try to install.
How do I stop this pop up message that has to be killed before Firefox runs? I don't want to Update and 4.0 is fine. Thank you in advance.

I have managed to stop that error message from popping up before the window loads up,
I deleted the entire updates folder from the program directory
C:\Program Files\Mozilla Firefox\Updates
now i dont get the silly message, firefox seems to be working fine :)
hope this helps
this worked for me. I went into the updates folder and deleted everything in it. problem solved. Be back if it reappears.
None of these files exist on my computer. Unable to use the info.
I have been searching through several forums to find a solution to this problem, and the only resolution I see is to delete the Updates folder, or files within it. Does the folder repopulate, or does this effectively disable updates?
Disabling updates doesn't sound like a very good idea to me.
I have this problem on my personal computer as well as my work computer, and on both I log on with an administrative account. It looks to me like there is a problem with the latest update.
UAC asks me if I will allow Firefox to make changes to my hard drive, I say yes, and then I get the error message above.
This solution does work for me on Firefox version 10.0.2.
This seems to be a windows 7 thing. Every version of Firefox in windows 7 has had this problem. It still exists for Firefox and Thunderbird release 12. Deleting the updates only delays the problem. It comes right back as soon as firefox retrieves the update again when you click on the about menu i think.
Why has no one from the Firefox development community taken a look at this and fixed it? The install/update is a large part of user experience, and it seems that almost a 1k people have this problem that have reported it here.
I finally figured this out and updated to version 13!
Ironically it was a feature specified in the new version that was causing the problem. It said that the new updates will no longer require a UAC dialog. That is incorrect, one must start Firefox as administrator so one no longer sees that message.
I have switched over to Chrome for a while now, I decided to check back in to Firefox to see if things have gotten better. (I was a dedicated Firefox user since the start.) I guess I am staying back on Chrome until Mozilla gets their stuff together. It is sad to say, but Chrome is still far superior and MUCH faster than this "new" bloated firefox, regardless of how many full-number "updates" they make. (Sorry, but version 13.0? That's a joke...14.0 will probably have a single bug-fix - perhaps fixing my inability to use the new "pin"-tab. :/)
OK rant over, to put it simply, if you get this error:
- Make sure you have no other versions of firefox running (I even check Task Manager and make sure there are no other Firefox processes running.)
- Right-click your firefox icon and select "Run as Administratror."
- Select "Yes" at the UAC prompt.
That should do it! Good luck Mozilla, I will try again in a few months... MikeY
EDIT - I should note that I first followed the other post and deleted my update directories before trying to do this. I know that without doing my step, it did not work; however, I do not know if deleting the folders is also necessary.

If the "silent" updates cause a problem, you can disable them here:
orange Firefox button or classic Tools menu > Options > Advanced > Update > uncheck the box for "Use a background service to install updates"
As for what is updated in Firefox's latest release, you can check out the Release Notes and detailed bug list.
