Cannot load firefox on this computer

I unistalled Chrome and tried to install Firefox but when I hit run, it appears to install but when I look at programs, it is not there nor is the icon.

hello Money2ski, could you specify how far the installation process is actually going - is the setup wizard (pictured in step 4 at [[Install Firefox on Windows]]) showing up?
some general troubleshooting advice for installing firefox: one thing you can always try is to right-click the setup file and run it as administrator. in case this doesn't work either try temporarily suspending the security programs you're using. in some cases it can also be malware active on a pc that is preventing the installation of firefox - please also do a full scan of your system with the security software already in place and/or a different tool like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes].

All of a sudden I cannot load Firefox. It gives this message: Script: chrome://tavgp/content/libs/include.js:595

I cannot load Firefox. I have been using it for years. When I click, the hourglass comes on for about 3 seconds then goes away nothing happens. I kept trying different things don't know what I did just before but at some point, it gave me this error message: Script: chrome://tavgp/content/libs/include.js:595
Thanks

That is a problem with an AVG extension (toolbar).
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

Changed out the hard drive in my imac mid 2007 intel. Once the disc loads, I get "Mac OS X cannot be installed on this computer." Help! Be gentle. I am truly a novice. Thanks in advance.

I changed the hard drive in my mid 2007 Intel Imac. I'm trying to re-install the the op system. I'm receiving a message stating that "Mac OS X cannot be installed on this computer." I am a "newbe" to Mac's. Can someone help? Please be gentle. I raeally am a novice. Thanks in advance

I believe these are the wrong system restore discs for your model iMac, assuming your are correct that you have mid 2007 iMac.
These gray colored type restore discs are Mac-machine specific and are the wrong ones for your iMac.
They will not work.
The original OS X restore discs for your model iMac would either install OS X 10.4.11 Tiger or OS X 10.5 Leopard.
You have gray system restore discs for a later model iMac. These will not work with iMac year and model.
Sorry.
You need to purchase a full retail version of OS X 10.6.3 Snow Leopard here instead.
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
These discs will work with your year and model iMac.
Assuming that your hard drive was installed properly, these white retail OS X install discs should be able to boot, format and install OS X 10.6 Snow Leopard to your 2007 iMac.
Good Luck!

"OSX Mavericks cannot be installed on this computer" is the message that I receive when trying to download Maveracks. I have a late 2007 iMac with Snow Leopard 10.6.8 installed, 167gb free space and 3 gb memory. What are reasons that it won't download?

Does your computer meet the requirements listed below?
To install Mavericks, you need one of these Macs:
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)

IMac G5 (Ambient Light Sensor):Mac OS X cannot be instlled on this computer

I have 3 iMac G5's identical specs. They will not install OS X 10.5, but they ran 10.4.11 just fine.
Specs: iMac G5 PowerMac8,2
CPU Type: PowerPC G5 (3.0)
CPU Speed: 1.8 GHz
Memory: 1 GB 2x 512MB PC 3200U-30300
DVD+R (dual layer) 5x read
- DVD±RW 5x read
- DVD±R 6x read
- DVD-ROM 8x read
This fits into the spec required to install OS X 10.5. However, when I attempt to boot from the install disk, erase local disk, erase and format disk using the disk utility, Mac OS extended, Apple Partition Map. I receive message Mac OS X cannot be installed on this computer. At one time I received a message Kernel Panic CPU 0 driver cannot be found for this computer.
I also attempted to install from external DVD±RW DL (non super drive) boots, loads the installer, then same error message. If you need more information ask? Any insight would be appreciated.

As should be obvious by now, your problem is caused by using a model-specific grey installer disk with another Mac model. Not only will it cause technical problems because is it not designed for this purpose, it is a violation of the license that comes with the Mac to use its disks to install the OS or other included software on another Mac.
You must obtain a retail copy of Leopard to install that OS on your iMac G5. You must have a license for each Mac you install it on, either the license that comes with that OS pre-installed on a Mac or the one that comes with the retail copy of the DVD.*
Also note that the grey disks for each Mac you own should be retained, as they include installers for the bundled software that comes with it & a model-specific Apple Hardware Test ("AHT") that must be run from that disk. You cannot easily duplicate the grey disks, in part because the AHT partition is not a conventional boot volume & a disk image file of the entire DVD must be written in a specific way to the duplicate to work like the original.
However, even if you manage to do this, the duplicate still cannot be used with another model, so the only reason to make a duplicate of a grey disk is as a backup for the original.
\* A site license or bulk license also meets this requirement, but you still must obtain a suitable installer disk.

I erased by Hard drive without backing up. Now, when I put the install disc one inside, it says that Mac os x cannot be installed on this computer. The computer was running Mac os x 10.5.8. Any help?

Boot from your DVD by switching on the Mac & inserting the disc, restart it & hold the "C" key. Once the installer window loads & you have selected your language, choose Disk Utility from the Utilities Menu. You will then need to select your disk from the menu within Disk Utility & choose how you wish to format. It should be formatted Mac OS Extended (Journaled).
Once it has formatted, you should then be able to install the OS.
PLEASE REMEMBER...that formatting a disk will completely erase it's content. Be sure that you don't wish to recover any of your previous content before doing any of the above.

Dear readers,
I have macbook pro 15" intel processor (from 2008 i think). Today i wanted to upgrade to snow leopard from 10.5.8 and i get this message "10.6 cannot be installed on this computer?"
I have free space on my hdd. I also booted the dvd manually by restart + alt, but i still get the same message. Any ideas why I can't upgrade?
Thank you

Do you have a retail Snow Leopard installer DVD? Did you do the following first:
Repairing the Hard Drive and Permissions
Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Then boot from the Snow Leopard DVD as follows:
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Your computer must have at least 1 GB of installed RAM to run Snow Leopard. Your hard drive must be partitioned using the GUID partition scheme and formatted Mac OS Extended, Journaled.
BTW, future questions about Snow Leopard should be posted in the Snow Leopard forums rather than here in the Leopard forums.

HT201364 Can't download Mavericks installer on recent Mac. "OS Mavericks cannot be installed on this computer", which is running 9.1.

I want to download the Mavericks installer so I have a backup installer that does not require the internet. Although, the App Store button allows me to download, I get a message that Mavericks cannot be installed on this computer.
Computer is late 2013 retina MBP 13" with lots of memory.
My OS is 10.9.1 (13B3116) currently running.
Is the App Store version of Mavericks too old (jan 16) for my rMBP?
Rick

Judging by the build number, it appears you have a special build of Mavericks installed and the App Store version (13B42) won't work with your computer.
Kappy - if I try to download Mavericks I get the message below, so apparently I can down load it again?
I also have a copy of the installer in my Applications folder, although it is in a folder.

Reinstall Lion problem: "Lion cannot be installed on this computer"

Hi, I just bought a new Mac Mini 2011 with Lion already installed on it. After use Time Machine to bring back my old data I found out the system wasn't working at the speed anyone would expect from a brand new product. As an example, it takes too long to login or to get the window to close one of the apps of the dock (it can take at least 5-6 seconds to appear...) Something that didn't even happen in my old MacBook.
For this reason I tried to reinstall Lion using the method described here: http://www.apple.com/macosx/recovery/
I even tried with the external Usb drive option but when the utility tries to verify the system I get this error message: "Lion OS 10.7 cannot be installed on this computer".
I will call Apple Techincal Service of course, but in the meantime... anybody has any idea about why this is happening?
Thanks!

Try:
Reinstalling Lion Without the Installer
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

CANNOT LOAD FIREFOX-LOOKING FOR PERMISSIONS-GIVES 2 CHOICES 1)USE CURRENT USER-(DOESN'T WORK) 2)USE -ADMINISTRATOR-ASKES FOR PASSWORD (I HAVE NO PASWORD) CAN I BE HELPED

cannot load firefox. goes thru the run process,that asks for current user or administrator.i click current and it just diappears.the second choice gives me a user name(ADMINISTRATOR). won't accept anything i put in as a password.

Check that you do not run Firefox as Administrator.<br />
Right-click the Firefox desktop shortcut and choose "Properties".<br />
In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected.<br />
Also check your security software.<br />
Remove all rules for Firefox 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.

These apps cannot be accepted on this computer error

I am trying to update iPhoto and iMovie from versions 9.3 (iPhoto) and 9.0.5 (iMovie) to iPhoto 9.4.3 and iMovie 9.0.9. I keep on getting an error message that reads "These apps cannot be accepted on this computer. Future updates of these apps can be found through Software Update." Well, software update just launches the App store. I have done extensive searching on forums and tried to delete the apps and run the updater like suggested, but it still does not work. There is also no option to "Accept" the applications in the Mac App Store.
I am running the latest version of OSX (10.8.4) and have never had problens updating before. I have a mid 2009 15' MBP and have been the only owner. My laptop came with iLife '09 and, as the very rude guy from apple support pointed out, I have never purchased iLife 11.. but have somehow been allowed to update through software update and the Mac App store (have never pirated the software, as the Apple tech suggested). I guess my question to you is:
1. Why is it suddenly giving me problems when I try and update the software and 2. How am I supposed to buy the software if I am only given the option to "Update." I would also love to know how I've been able to keep updating for this long without having to pay for iLife '11.
Thanks for your help.
Corey

There are problems with some of what you describe. iLife '09 was not Mac App Store (MAS) software. iLife '11 originally was also not MAS software. iLife '11 is a major paid upgrade from iLife '09 and Software Update (SU) would not have upgraded your iLife '09 to iLife '11.
iLife '11 did not transition to the MAS until after the MAS was issued to the public as beta software for OS X 10.6.6 in JAN 2011. After that, Apple began phasing boxed software out of their stores as the supply ran out and iLife was issued as 3 individual apps for $14.99; iPhoto, iMovie and GarageBand, sold only in the MAS. The MAS cannot update the original boxed version of iLife '11. Those apps can only be updated through SU.
So the part of your story that doesn't work is how you got from iLife '09 to iLife '11. You did not get there through SU. And if the MAS is reporting that those apps must be updated through SU, they would be the original, none-MAS versions that came preinstalled on new Macs or as boxed software. Could you have transfered these iLife '11 apps from another Mac? A Mac that is newer than your own and would have had the boxed set versions of iLife '11 preinstalled?
