Why can't I install Firefox as an unprivileged user?

I can't install Firefox without letting it alter my system. I can install all other browsers as an unprivileged user, but not Firefox.

Did you try your solution? As soon as I cancel UAC prompt, installation aborts. I can't start installation without it showing UAC prompt. Thus I can't choose path to install browser. You know, all other browsers allow to choose installation type between "All users" and "Current user". While "All users" type requires admin rights and UAC prompt appears if user chooses it, "Current user" does not require admin rights, so no UAC prompt appears if user chooses this type. With Firefox I am not given the choice. It requires admin rights as soon as installation is launched. It even ignores set __COMPAT_LAYER=RunAsInvoker environment variable.

Why can't I install firefox in the language of MY chosing?

I get sometimes very tired of preassumptions on websites that are hard to change.
The Firefox download takes that to the extremes. Why can't I just install and UK version and get all the time prompted to download the NL version. I am working internationally and want all my programs to be English, so this presumption is more than just frustrating, it is wasting time and injecting lots of negative energy!

Why can't i install firefox on windows 7

When I try to install Firefox on my windows 7 desktop platform (running this as an administrator), I can download the install file "Firefox Setup 4.0.1.exe", but when I run the file (also as administrator), I get an 'Extration Failed' pop-up stating that it cannot open an output file.

Will it work if you right click the downloaded exe and choose run as administrator?

Why can't I install Firefox for Android on my Motorola Defy Mini? According to Antutu Benchmark system info, it has a ARM v7 CPU, so it should be compatible...

When I try to install Firefox for Android on my Motorola Defy Mini (XT320), Google Play Store tells me that my device is not compatible with Firefox for Android,so I cannot install it; according to Antutu Benchmark system info, the Motorola Defy Mini has an Arm v7 CPU installed, so it should be compatible with Firefox for Android...

Turns out it was a permissions issue, the files created by the certutil in the defaults folder got root only permissions given to them. I opened them up and it's working fine.

Why can't I install Firefox?

Firefox would open, but instantly freeze, so I couldn't even reset it. The only way to close it was through the task manager. I decided the only thing I could do was uninstall and reinstall, so I did that. It downloaded but the set up wizard never started. I can't even find it listed in my downloads. I am having to use IE to send this message. Please help!

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, #p#ly 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.

Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will lose all personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*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 personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.

Why can I not install Firefox anymore using -ms?

I use to be able to install the downloaded versions of Mozilla Firefox using a simple switch on the command line. The switch was -ms. It worked great through, I think, version 24.0. No versions after that have worked. Is there a reason? It there an "easy" workaround? I've seen stuff that tells you create a config file and add it to the install. Surely there is an easier way? Anybody know something that will work? Appreciate any help with this.

Thank you so much!! This is exactly what I needed and is working.
Appreciate you taking the time to respond. :o)

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)?

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.

Why can't I use firefox as my browser on my iPad

Why can't I use firefox as my browser on my iPad also why can't I access adobe flash

Flash is not supported on any iOS device (iPad, iPhone, iPod Touch) : http://www.apple.com/hotnews/thoughts-on-flash/ . Apps such as Skyfire claim to support flash, but their reviews are mixed.
In terms of Firefox, you can only install apps (i.e. programs) that are available in the iTunes App Store, not normal PC or Mac software - the iPad runs iOS, not OS or Windows. If the makers of Firefox havn't created an iOS version of it then you cannot run it.
Edit : some websites (especially news sites) have their own apps in the App Store

Why can't I install Snow Leopard on my videos hard drive?

I have a Mac Pro with four hard drives. Lion is on the primary drive but I need Snow Leopard for a legacy app. My plan is to install Snow Leopard on a hard drive that I use for video projects, and then restart from that drive when I need to use the old app. The problem is that the Snow Leopard installation disk says that it can't install onto the videos hard drive unless I partition the hard drive, which will erase all the data. Why can't it install onto the videos hard drive? There's no operating system on that hard drive. The hard drive has folders for Final Cut Express Projects, iMovie Events, iMovie Projects, DVDs movies I've ripped, a folder of music, and an iDVD project. What do I need to remove to enable installing Snow Leopard?

If I understand what you are saying you have a drive with "stuff" already on it and you want to install a version of OSX on to it while still retaining that "stuff". If that's what you want to do you cannot do that mainly because there's already "stuff" on that drive.
The only way you can do this is to either of the following:
a. Copy the "stuff" off that drive to another drive. Install the OS. Copy the "stuff" back on to the newly created boot drive.
b. Copy the "stuff" off that drive on to another drive. Partition the drive into at least 2 partitions; one for the boot and one for the "stuff". Install the OS into one of the partitions. Copy the "stuff" back to the other partition.
Either way, if you want to use that disk for a boot disk, you got to get that "stuff" out of the way to do the OSX install on to that disk.
