Firefox won't install

I can't instill Firefox on my Macbook. When I move it to applications it only creates a shortcut. Any ideas?

Your phone has an ARMv6 processor, so you can only experiment nightly builds (crashy for ARMv6) as stated in [https://wiki.mozilla.org/Mobile/Platforms/Android#System_Requirements System Requirements for Android] (red list).
No beta or final version of Firefox Mobile 4.0 is scheduled for your phone.

I wish to install Mozilla Firefox as my Browser having re-installed XP Home Edition on my 'old' Dell losing my Service packs, so Firefox won't install.

As I am on the early XP, without any Service packs, I want to up-date to SP3. The Microsoft Website won't offer any help. Firefox won't install and I need a prompt to send me in the right direction.
I am using IE version 6.00 and it is refused access to updates because it is so old.
The 'old' Dell runs well but had suffered my bad management one night resulting in the need to re-install XP. It is my second PC and I am running 8.1 on my newer machine, so I can access help topics.
What is my next step please?

See if this works to get the XP2 and XP3 updates.

Firefox won't install on Windows 7 64-bit.

I just installed a new hard drive on my system with Windows 7 64 Bit OS. Same that I used on the old hard drive that crashed. I downloaded the installer, and have tried to run it both with and without administrator permissions (by right clicking on the file). the UAC asks me if I want to proceed, i say yes, I get a flash of some window and then . . . . nothing. I have downloaded a another copy of the executable, with the same results. I am using my laptop to post this.

Firefox is normally pretty simple to install. Look at any security software you have installed is any of that somehow blocking or preventing the change.
* Please list all security related software you are using ?
Ensure it is a genuine copy of Firefox from for instance

Firefox won't install for all users in Windows 8.1; only installs for administrator

Since moving to Windows 8.1, I have been unable to install Firefox for multiple users on this laptop. Firefox installs only for the Administrator (me), and does not appear on any other user account. When I try installing from one of the other user accounts (after entering my administrator password), it simply won't install.

Check that Firefox isn't set to run as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
* Privilege Level: "Run this program as Administrator" should not be selected
* "Run this program in compatibility mode for:" should not be selected
Also check the Properties of the firefox.exe program in the Firefox program folder (C:\Program Files\Mozilla Firefox\).

Firefox Sync doesn't recognize my version of Firefox, won't install

Whenever I try to install Firefox Sync, it tells me "You are currently using Firefox 3.0.13," won't install, and suggests that I upgrade. However, I'm using Firefox 3.6.10, so I don't know how to resolve this. (Yes I tried downloading and installing the upgrade... this is still the result.) Any ideas?

Awesome suggestiont. Your solution worked perfectly and it was a breeze. Thanks!!

Firefox won't install; it says extracting and then completely stops.

So I've tried installing firefox several times on my computer. For some reason IE (32-bit browser) is not longer working but the 64-bit browser is. Flash isn't compatible with the 64- bit browser so I decided to install firefox. However, every time I try I get to the part after the second installation pop-up where you click run, and it says extracting, it gets to 100% then disappears, and nothing happens. It never gets to the installation wizard. I've run spyware scans and registry scans and there does not seem to be a problem. Can anyone help?

After an hour or so of searching the interwebs, I found this:
''Given the security of model of Vista and Windows 7, even though you are logged in as an Administrator, you are NOT given the Administrator token until you elevate. Simply right click the setup.exe and select Run As Administrator, you will be prompted with a Yes and No dialog box. Click the Yes button and you will be able to install Firefox. I have Firefox and Chrome installed without any issues.''
''By default, the Built-In Administrator account is disabled in Vista, Server 2008, and Windows 7.''
This worked for me, it should work for others as well!

Firefox won't install after downloading.

I recently was having troubles with Firefox, I was running Firefox Beta 18 - it started saying it could not update. So after repeat failed attempts, I figured I'd uninstall it and re-install a fresh version. It will download, I can find the file folder, but even when I try to run it as an administrator it won't open the installer. I downloaded three different versions, all do the same. I'm currently running Windows 8 and have had Firefox for over two years on Windows 7. When I upgraded to Windows 8 it transferred seamlessly with no problems. I'd like to be able to use Firefox again.

You can try booting the computer in Safe Mode with Network Support. This can be done by opening msconfig.
# Enter Desktop mode by pressing Windows Logo + D
# Windows Logo + R
# Type ''msconfig'' and press Enter
# Click on the ''Boot'' tab and choose Safe Mode with Network
# Click Apply/OK
Then restart your computer and it should automatically enter Safe Mode with Network Support. From there, find your installer and try running it again. When it's done, make sure to go back to msconfig and uncheck Safe Mode.
Finally, restart the computer.
Hope this helps!

Firefox won't install after uninstall

Hey all,
I just bought a new 2012 rMBP and a local authorized computer repair shop transfered over my data from my old laptop, which was a macbook as well. The only reason i had them do it is because my old laptop was subject to severe water damage, and I had no way to access the HDD
Anyway, he transfered over my apps, files, and everything. Firefox was transfered over as well. I uninstalled firefox by dragging it from the applications menu to the trash, and then downloaded the current copy (the one that was installed on my old laptop was 6 releases behind). I go to install the newly downloaded copy and it tells me there is already a firefox installed, and i can replace, leave it alone, or stop. If I pick "replace" it gives me a message of:
"The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again."
I've searched for firefox files and there are none.
Where do I go from here?

Back up all data if you haven’t already done so. Before proceeding, you must be sure you can restore your system to the state it’s in now.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo chflags -R 0 /Applications/Firefox.app
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. If you don’t have a login password, you’ll need to set one before you can run the command.
Try the installation again. If it works, you can quit Terminal.

Firefox won't install on my computer

I've had firefox installed on my laptop forever. Lately, it's been having trouble updating firefox. I removed the firefox program and then tried to reinstall it on my laptop. I click on the download button and click run but nothing ever happens. I even tried saving the program and same thing. It saves I click on the setup and it still won't download. PLEASE HELP!!!!

Hello lynchsta ,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then install Firefox. Please follow these steps:
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
Or better yet, download the full setup file here: https://download.mozilla.org/?product=firefox-33.0.2-SSL&os=win&lang=en-US ( I assume that u use windows and language English US ) . For other builds: https://www.mozilla.org/en-US/firefox/all/
# Before trying to install it, 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.
More information about reinstalling Firefox can be found [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
WARNING:Do not use a third party uninstaller as part of this process. Doing so could permanently delete your [[Profiles|Firefox profile]] data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See [[Back up and restore information in Firefox profiles]]. 
Please report back to say if this helped you!
Thank you.

Firefox won't install on my Mac, it just finishes the installation then does not appear in my Applications folder.

Firefox offered to create a new profile for me, but took forever to do so so eventually I had to shut off the computer. In restarting, initially Firefox would not open as "Profile could not be found". Having moved Firefox to my trash folder, when I attempt to install Firefox again, it completes the download, then does not appear in my Applications folder.

This is likely caused by a problem with the profiles.ini file and the profile marked as Default=1 in this file is not present on the hard drive.
*Mac: ~/Library/Application Support/Firefox/
You can use one of these to make Firefox create/use a new default profile:
*Delete the profiles.ini file to force Firefox to create a new default profile
*Use the Profile Manager to create a new profile
*Use "Choose Folder" when you create a new profile to select the location of a lost profile and recover this profile

Download and save the full Firefox installer to the desktop and start the installation with a double-click on the desktop icon.

When downloading Firefox, the second time I click run I do not get the set up wizard and Firefox won't install on my PC. Why?

When I first click download and run, It takes about 2.5 minutes to download the program. It then prompts me to click run again, but this time instead of taking me to the Wizard as it says it will, it processes for about 2 seconds and all prompts go away without installing Firefox.

Hi sahgin,
The issue eventually resolved itself, I still don't really know why. I kept up with Windows update, and attempted downloading iTunes again from the Apple website, and it just... worked. It now works fine. I don't know why it took approximately 4 months to work, though.
I'm sorry I don't have any more helpful information. Posting here was my last resort, and clearly Apple never bothered to reply.

Why won't firefox won't install on my imac with ox 10.5.8?

I am trying to install firefox for the first time on this machine. It will not install. It seems to be incompatible. Can I install an earlier version?

Hello, Thank you for the reply. I have the SDK tool but haven't had much time to work with it and get it to run proper. It is a new phone and "ATT" has disabled several features on it as to restrict usage of thier phones. I Did get Fennec to install from your feb 22 update (#4.06pre) and so far it runs great. So I will try and use it as much as possible to test it out. I don't know what changes you made from the one in the android market to that one but it fixed the problem and thank you.

Firefox and OS 10.2.8 - Firefox won't install

I've been trying to get Firefox to install on a G4 running OS 10.2.8.
Roam was kind enough to offer some suggestions, (I've posted under a different user account but didn't like having my full name "out there") but I'm still at square one, which is: after properly intalling Firefox, the icon just bounces in the dock and will not run. I've run the repair disk function from the installation disk, run "repair permissions" several times, etc. I've posted on Mozilla's forum as well.
The goal in all of this is to be utilizing a current, secure browser. Others in the forum have suggested browsers like Camino, but they are not compatible with 10.2.8 from what I've seen or are not currently supported with security updates, etc.
I would appreciate help getting this issue resolved!!!!
Thanks!
Jeff

I don't know... Since it works with the new user, you've narrowed it down to something in the old user's folder.
You can try deleting the FireFox preference file at
<user folder>/Library/Preferences/org.mozilla.firefox.plist
Or deleting the FireFox cache at
<user folder>/Library/Caches/FireFox/
If it's too hard to figure out, your mother and sister may need to migrate to a new user account (or accounts if you make one for each of them).

Firefox won't install bc of "Unsupported Architecture" when I clearly meet the System Requirements?

I installed Firefox 4.0 and upon clicking on the mounted image, I dragged and dropped the program into my applications folder, then because of unsupported architecture the program wouldn't launch. However, I read the system requirements before installation and I meet all of the above. I have a PowerMac w/ a Dual 1.8Ghz PowerPC G5 based processor, 1GB DDR SDRAM, and a 320GB Hard Drive running Mac OSX 10.5.8. After which I had to delete the program and restore firefox 3.6.16 using Time Machine.

Firefox 4 doesn't run on a PowerPC Mac. 
Firefox 4 requires at least OS X 10.5 and an Intel Mac.

For Mac OS X 10.4.11 or Mac OS X 10.5.8 you can look at:
