Every time I launch Firefox it pops up an error stating "Firefox could not install this item because "install.rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem."

Firefox could not install this item because "install.rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem.
The statement above is in the pop up error box every time, when I launch Firefox. If I click ok in the box Firefox then opens. How do I fix this initializing/launch problem?

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). 
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. 
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions. 
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Everytime firefox updates I loose my Blue Mountain access. the pop-up reads Create & print plug-in could not install because it is not compatable with firefox 4.0.1

went to use create & print in bluemountain got "In order to use create & print in Mozilla you must download and install latest version. Do you want to install plug-in?" (clicked OK). Next message was "Firefox prevented this site (www.bluemountain.com) from asking you to install software on your computer" (clicked Allow) Next message "Create & Pring plugin could not install because it is not compatible with firefox 4.0.1" -- this sound like a firefox problem not bluemountain. Please help... I am paying to use bluemountain and firefox is not letting me get my $$$$ worth out of that site.

Launch Disk Utility in /Utilities. Then, click on the volumes under the top-level disk. The one that has this listed on the bottom is the boot volume.

Firefox could not install the search plugin from "chrome://tnt2toolbar/content/yos.xml" because an engine with the same name already exists.

each time I open Fire Fox I get this error "Firefox could not install the search plugin from "chrome://tnt2toolbar/content/yos.xml" because an engine with the same name already exists." and
I can't search for anything. HELP!!!
Thanks
Tom

That is a problem with an extension that tries to install a search bar. The tnt2toolbar should give you a clue about which extension. You didn't add troubleshooting information with the list of installed extensions, so I can't give a suggestion about which extension is causing this.
You can check for problems with preferences. 
Rename or delete the prefs.js file and possible numbered prefs-##.js and user.js files to reset all prefs to the default value.

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

Help I need help. i get this message'Firefox could not install this item because "install.rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem.' How do i fix this?

Firefox could not install this item because "install.rdf" (provided by the item) is not well-formed or does not exist. Please contact the author about this problem.
Well that is the message i get. I can still use firefox(version3.6.8)

You get that error if an extension is using an old and no longer supported method to install a plugin.
Which plugin are you trying to install?

I don't think there is any upgrade that you can purchase for CS2. If you need to reinstall CS2 then see the following...
CS2: Error: Activation Server Unavailable | CS2, Acrobat 7, Audition 3 -

I erased my HD and could not install lion. if I turn on the mac now all I see is a folder with a question-mark. How can I install a new operation system?

Install or Reinstall Mavericks, Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
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. Alternatively, 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.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

When I try to download Firefox 5.0 (I have 4.0) I get the box that indicates that Acrobat could not open 'Firefox 5.0.dmg' . Mac OS10.6.7 Help!

I keep getting the Software Update for Firefox 5.0. I try to update after viewing the informatiion choosing English and MacOS X. It downloads and then I get the message: "Acrobat could not open ‘Firefox 5.0.dmg’ because it is either not a supported file type or because the file has been corrupted (for example, it was sent as an email attachment and wasn’t correctly decoded)."
I would be most grateful for any help; I am 78 and trying but not succeeding. Ah, the scourge of age.

Sorry, Firefox 4.0.1 isn't supported any longer, that's why you are getting re-directed. Firefox 5.0 is a security update for 4.0.1; Firefox 4.0 didn't get that update, but Firefox 3.6.18 did. Best to stick with 3.6.18 until whatever you are using for those logins is updated for Firefox 5.0.

Trying to install the new itunes update and it keeps saying error could not install itunes. Currently I am running windows 7. Any advise to fix this problem.

Trying to install the new itunes update and it keeps saying error could not install itunes. Currently I am running windows 7. Any advise to fix this problem. This is doing this when installing itunes/quicktime, safari 5, mobileme control panel, and the software update itself. The itunes version is 10.3.1

That suggests that the installer is getting damaged during the download.
I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

OS X could not install on this disk. Not enough disk space

Hi,
Disclamer here is that I am completely new to the Mac world after having used purely Windows for the last 15 odd years so sory for any silly mistakes
I tried to do an upgrade on my Mac Book Air but am running into a really annoying issue am hoped that someone would be able to give me some much needed help.
I downloaded Mavericks from the app store with no issues. I then tried to do the upgrade and I get to the OS X installer screen, were I chose my language then hit next. I then select the harddrive to install on press install. I then get to the Installing X screen and status says Installing OXS on the disk "Macintosh HD"
After a few seconds I get a message saying "OS X could not install on this disk. There is not enough space on this disk to install the selected items. Deselect at least 1.16 GB and try again"
I appreciate that I need to delete some files but how can I get get to the files in order to delete them as, as soon as I resart the PC I get caught in the same loop
Manu thanks for taking the time to look at this and for your help

If you cannot get into your Mac at all, if you MacBook Air is still under AppleCare, you can purchase an external hard drive to connect up to your MacBook Air (MBA), bring both the drive and your Mac in an Appe Store or Apple Auhtorized reseller/repair center so Apple techs can install a bootable copy of OS X 10.9 Mavericks onto the external drive where you can boot to that drive from your MBA and access your MBA's internal hard drive and start cleaning off and archiving data.
You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Delete any other mail in your Junk folders. Also, look through your Sent Mail to see if there is anything that can be deleted.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

"Adobe Acrobat could not install correctly"

Has a fix been found yet for this damn annoying problem.
I get this message regularly on my Mac G5, Leopard 10.5.2. I must have reinstalled the program about 5 times by now. It works properly for a few days, then this-
"Adobe Acrobat could not install correctly"
"A required component was not found, please restore the Adobe Acrobat folder from your original CD".
Doing a forum search, I noticed people were having this same problem as far back as October 2007. Has it been resolved yet, and if so how?

I discovered that when I initially install Acrobat it works fine. However, after I run the program Monolingual, which removes languages and architectures that my Intel Mac does not require, Acrobat has this exact failure.
I went to Monoligual's website and in their FAQ's they address this issue. (http://monolingual.sourceforge.net/faq.php) You simply need to add the Acrobat folder (/Applications/Adobe Acrobat 8 Professional) to the Monolingual preferences list and then uncheck both boxes. Also, with Acrobat Professional 8.1.4 you need to add the folder /Library/Printers/PPDs to the list and uncheck both boxes, because Monoligual will delete four Asian Language folders from this folder and Acrobat will give you an error if they are not there.
So, if you use Monolingual, or some other program that removes languages and architectures, this might be your solution.

10.5.2 The Installer could not install some files in "/"

I have tried to upgrade my Inter Mac Mini Core Duo 1.66 to 10.5.2.
I ran the install through software update and proceeded through the 2 restarts. Once my mini restarted I checked "about my mac" to find that it still said the system was 10.5.1
I ran software update again to find that on trying to install i now get the message
Install Failed - The installer could not install some files in "/" please contact the software manufacturer for assistance.
I then tried the same with the combo updater and got the same message
I have tried to verfiy my disk or repaire permissions using disk utility for it to completely hang with the spinning beach ball and causes finder to crash.
I have also booted up with the leopard disk in and tried disk utility which says there are no problem with the disk but disk utility in leopard still hangs
Can anyone help??
Is anyone getting the same problem?
Thanks

I'm having the same problem installing the Leopard Graphics Update on my Dual 2.5 G5. Installing 10.5.2 went fine, but afterwards the graphics update would fail to install, with the same error message you got. I tried both Software Update and downloading the standalone installer.
But wait, there's more! I also can no longer repair permissions using Disk Utility. I get the following message: "Error: The underlying task reported failure on exit." Booting from my Leopard install CD does allow me to fix permissions.
Lastly, my second internal hard drive is now also behaving oddly, Any time I try to drag a file to the Trash, I get a dialog box telling me: "The item "(file name)" will be deleted immediately. Are you sure you want to continue?"
I've run DiskWarrior from the CD and tried fsck in Single User mode (no errors found). Nothing seems to help
I had no problem updating to 10.5.2 on my MacBook, but the update to my desktop has been a real booger. Anyone who can offer any input, I'd sure appreciate it.
