Poke around safe web sites and see if there is still a problem. Then restart.

Just downloaded latest version and now Firefox won't open a new tab. How do I fix this?

I've been using Firefox for years, however as of last week I can no longer open a new tab. I have to go to "file > new window" new tab quick function nor dropdown work. I'm using a Mac OS X 10.9.3.

Hello, discodiva64
Thank you for the question. Try uninstalling all components of iTunes in the order specified of the article below. Once this is done attempt to install iTunes again.
Removing and Reinstalling iTunes and other software components for Windows XP

If the issue persists, I would recommend going through these steps for error 7.

If the issue still persists, you may need to process the steps in the article below for each component when uninstalling iTunes.

I upgraded my Itunes to the latest version and now it won't let me view my library with the column browser. Can i get that back?

i upgraded my Itunes to the latest version and now it won't let me view my library with the column browser. Can i get that back? I tried using the shortcut for it and nothing happens. When I try to do it from the view menu, it shows up as something I can't click on. The new library format is driving me crazy and I just want to get back to the old library view.

We need to sort out some facts here first:
• You cannot be running Mt. Lion on your iMac G5. What Mac is it? What is the Model Identifier listed in About This Mac; More Info; Hardware Overview
• What is the model of your Epson Scanner?
• Have you attempted to scan using Image Capture, located in your Applications folder?
• Your Palm Pilot software will only run in Snow Leopard; so depending upon which Mac you have, you will either have to:
1) partition your hard drive or add an external hard drive and install Snow Leopard into it to "dual-boot" when you want to access you Palm software, or
2) install Snow Leopard Server (now available from Apple for $20 telephone orders USA & Canda only) into Parallels 8 to run your Palm software in Mt. Lion:

Uninstalled new version, horrible. Installed the older version and now it won't open! HELP WANT MY MUSIC!

I installed the new version thinking it would be the same, It was horrible! uninstalled it... Installed the older version and now it won't open and when I try it says it can't because the library can't open because it was used on a newer version. Come on! I just want my music! How do I open this and get my music back.
I put my Ipod in and it still says the same thing, what's going on? Please help me!

I don't know whom to thank first-- b noir for telling me about the Lorraine fix or Lorraine for figuring out the fix. THE LORRAINE FIX WORKED FOR ME!!! (I feel a little like I am advertising "Hooked on Phonics" with that last line!)
Thank you doesn't say it strongly enough, but THANK YOU b noir and Lorraine for your help. I was to the boiling point last night and starting to get there tonight. Now I am resting easy and thankful that there is a community of computer users out there who care enough to troubleshoot problems together and work together to figure out a solution--and then to take the time to post and share information.
I would STRONGLY suggest that anyone who is having the iTunes issues where iTunes just plain won't open at all after downloading the newest version and has a pc with Norton Internet Security 2005 try the "Lorraine Method."
I am so happy I think I might sing. Or not--I will let my songs on iTunes do the singing for me now that I can again!!!!!!!
And to those still looking for answers--be patient--I now know how incredibly frustrating this can be and I hope that you all find your solutions very very soon!!

You did a d/l of the iTunes .dmg - did you install by opening the .dmg and following the dialogs?

I changed my setting to private browsing and now firefox won't open. Any ideas?

In what way did it not open? Was the Firefox icon on the task bar?
Did you get any error messages? Did the computer show Firefox
as running?

I just updated to latest Firefox version and now it won't open at all. I even tried to go back to the previous version using Time Machine on my Mac and FF just won't open.

Firefox won't open after downloading latest version this morning.

Hi, JEvansIII.
Thank you for visiting Apple Support Communities.
Try resetting your System Management Controller or SMC then launch iTunes after processing these steps. If the issue persists, try downloading a fresh copy of iTunes by accessing the second link below.

Updated to 4.0 version and when it loaded I got 4 identical icons on my desktop. I went back in time on my computer and now Firefox won't open.

Updated to 4.0 version and when it finished loading I got 4 identical Firefox icons on my desktop. I went back in time on my computer to go back to an order version and Firefox won't open or is very slow to open.

Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0: http://www.mozilla.com/firefox/all.html
* Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* 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.
* It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Interrupted while setting about:config. Came back and now firefox won't open for more than 1 second.

As above. looked up and was late to work. never 'closed' file or settings.
Came back from work and now firefox opens for about 1 second and automatically closed
down immediately. I've removed it. uninstalled it. redownloaded it. still does same.
Now I can't go back in and recheck the config settings, because it won't stay open long enough
to even work on it.
I had remotely saved my bookmarks, so that's the most valuable thing.
I'd be happy to wipe it off my disc and simply replace it and start all over.
How can i get that done? I'm not a super pro, so direct steps would be really useful.

You can try to delete the prefs.js file in the Firefox profile folder.

I downloaded a new version of iTunes and now Firefox won't open iTunes

I loaded new version of iTunes and Safari. When system restarted - iTunes won't open. I deleted Safari - still no go.

I'm having this issue as well. Anytime I click on items that would normally open in Itunes, it tells me I need to install Itunes. I've uninstalled/reinstalled Itunes to no avail. In looking in Firefox's preferences, there's no reference to Itunes in the Applications tab.

I trashed my mimetypes.rdf file to reset download actions, and now Firefox won't open because profile missing, please advise

Up until recently, when I would download a pdf file, it would automatically open, and recently, for some reason, it stopped opening automatically and just downloaded to my desktop where I wanted it. I found instructions on Mozilla if files downloaded but not displayed, that included displaying my profile folder and then deleting it. I trashed it (different from deleting?) and now if I try to open Firefox, I get the message that Firefox can't open/load because profile is missing. Please advise how I can get the profile folder back in.
thanks

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.

Whatwhere is the plug-incontainer? happened to the plug-in container? it disappeared with the latest version and now firefox freezes multiple times each day.

I don't see the plug-in container in the Windows Task manager since the last update of Firefox and now FF is freezing multiple times a day (since the previous update, before yesterday's). It takes several minutes after I see this until it unfreezes, and it's quicker to "end task" and re-start Firefox than wait. This most often seems to happen when the computer's been idle for awhile, rather than when I'm using it.

Make sure that you allow the plugin-container process in the firewall.

Downloaded Safari Update and Now Safari Won't Open

This past Sunday I was informed that I needed to download an update for Safari. I did this (during a major thunderstorm, but never lost power) and everything seemed to go through properly and worked normally. I restarted my computer when it prompted me to do so. A couple hours later I tried to get on the internet and nothing happened. The icon bounced a couple times and Safari's name popped up at the top of my computer next to the apple icon, but no window opened. I tried to hit open new window and so on....when I got frustrated and quit Safari it told me me that I had like 7 windows open and did I still want to quit. I clicked yes and then another window popped up stating that Safari encountered a problem and needed to close unexpectedly. I reported it to apple like 12 times. When I called apple they expected me to pay for them to fix it, even though his explanation was "This version of Safari is probably not compatible with Tiger". The other issue is that my disc drive went bad a couple years ago and I never fixed it, so I could not re-install the original Safari. Can anyone help me fix my internet without having to pay a computer store??

HI,
If the optical disk is broken, then you can't use your install disk to repair the startup disk if necessary.
Try booting in Safe Mode
It takes a little longer then a normal boot. Once you are in Safe Mode launch Disk Utility (Applications/Utilities)
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
Click Verify.
At least this way you will know if there are problems with your startup disk before trying to troubleshoot Safari.
When you are finished click the Apple Menu / Restart.
Also I was able to delete my cache and now I can make an attempt to open a new tab, but then it immediately closes and gives me the unexpectedly had to quit message this time with a new number at the end of that KERN blah blah blah one and that number if it helps is 0x0000000c
If the startup disk is ok, post a crash report.
If Safari has just crashed, press the Report button on the CrashReporter dialog box to view the crash information.
Now copy/paste the entire contents of the Crash Reporter window into your reply here. If the crash report dialog does not appear or the crash is hard to reproduce, crash logs can be retrieved from the ~/Library/Logs/CrashReporter> folder.
