Can only open firefox as admin, otherwise get error to say a security component could not be initilaised. Have tried deleted cert8 file but it is not recreated and still will not open

Had problems with os and now can not open firefox unless I run as admin. Error appears - Could not initialise the application's security component. The most probable cause is problems with files in your browser's profile directory. Please check that this directory has no read/write restrictions and your hard drive is not full or close to full. It is recommended that you exit the browser and fix the problem. If you continue to use this browser session, you might see incorrect browser behaviour when accessing security features.
I have tried deleting the cert8 db file but it is not recreated when I start firefox again. HD has lots of room. Can you suggest anything else to try please?
thanks, mandi

If deleting or otherwise removing the cert8.db and secmod.db file doesn't help then try a new profile.
*https://support.mozilla.org/kb/Could+not+initialize+the+browser+security+component
Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

I have tried to download the update for itunes several times and it will not complete, i get an error message

I have tried to download the update for itunes several times. Each time it get to the installation part and stall and then reverses and give me an erorr message. My current version when I open it, it says there is an error and I will not be able to download a CD into itunes, although I have completed several CD downloads.

Go to http://www.mozilla.org/en-US/firefox/new/ and download the full installer. Run the installer and you will be up-to-date. Sometimes the updater just gets in a weird state...

2009 MacBook Pro eh? It looks like your hard drive has failed. Three years is pretty standard. Often, then only hint you have is catastrophic failure.
If you put the old hard drive into an external enclosure or similar device, you may still be able to migrate your data from it. Just because it won't boot doesn't mean you can't still read from it. Still, I wouldn't keep trying it. As long as you are buying a new hard drive, may as well get sometime to use with Time Machine too.

I'm using Mac OS 10.4.11 & even typing this message the characters appear so slowly that I could get a hammer and chisel and inscribe the words faster than the new Firefox runs. WTF?

I have an older version of iTunes on my office computer and it will not let me update to the current version without an administrative password. How can I get around this??

If you have an iBook G4, (PPC) you can't do much.
But if that is a MacBook (intel) you may be able to
upgrade the OS X, if the hardware is up to it...
Since there were about nine different build models
of MacBook (not powerpc iBook) to identify what
one you have would be the first step to knowing
what OS X and RAM upgrades it could use.
If the computer is not already at OS X 10.6.8,
it can't go online to get or use OS X 10.7.5. So,
when you more accurately describe the 'Book,
detailed information is available.
When you find the serial number, there is a web
page that can be used to identify by serial no.
http://www.powerbookmedic.com/identify-mac-serial.php
That'd be a first step. Or even the Model number
which should be visible on the outer case by hinge.
Good luck & happy computing!

I uninstalled it and now am trying to reinstall from the CDs that I own and it will not read the disk. Nothing happens. I had previously downloaded it to my laptop and work computer. How do I install it again?

You can't run PSE from a USB drive, nor can you transfer PSE to a different computer via a USB drive. PSE must be installed on a computer using the installer program provided by Adobe.

'The installer has insufficient privileges to modify this file C:\Program Files (x86)\Common Files\Apple\Apple Application Support\Web kit.resources\inspector\Images\Spinner Inactive Selected.gif.'
That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?

When trying to download apps to my ipad, I get a message saying a secure connection could not be established and to check my date and time settings?

When trying to download apps to my ipad, I get a message saying a secure connection could not be established and to check my date and time settings. Can someone tell me what this means and how to fix the problem?

It's a POP account. I decided to clean up my mailbox today after noticing the computer was real slow after USA Today started sending their daily top stories with new graphics. Also before I noticed the problem with mail deletion - two things happened. 1) I updated security sofware as prompted by Apple and 2) downloaded Mackeeper and went throught some preliminary scans but did not buy their package. Thanks forn nstaying with me.

HT1645 whether i use a DL DVD or just a DVD R, it tells me there was an error during multiplexing. I have tried changing every setting, best performance, professional quality, etc. and still get the same error message every time i try to burn to dvd.

Welcome to the forums.
Looks like that error message does refer to encoding (see http://support.apple.com/kb/HT1645) but a problem could be that your video has to be reloaded into iDVD if you started the encoding process and then switched settings. You could start a new iDVD project, or try deleting encoded assets.
Let's start from the beginning -- what length of video are you trying to fit on the DVD? (this will indicate what encoding options you have). Double layer DVDs can be finicky and are used for video more than 2 hrs long.
Use good quality media -- Verbatim is often recommended around here, and I've used Sony DVD-R with good results.

After accepting update to my time capsule, I can no longer complete a backup because there is not enough space. I tried deleting old files, but it doesn't seem to work. Any advice:

My time capsule was updated through an apple download update on June 16, and now I cannot back up my computer. The message is that there is not enough space. I tried deleting my files, but it didn't help. any suggestions?

How much space is there according to airport utility?
TM can be fussy.. Do a factory reset of the TC and give it a new name. Use short, no space and pure alphanumeric type names..
And reset TM. See A4 here. http://pondini.org/TM/Troubleshooting.html
Then set up TM again to the TC and see if TM will start .. the reset will not hurt the backup and TM can still find it on a renamed TC.

If so, then they are gone.
