I can't open firefox in safe mode -- firefox is frozen, I can't open the firefox menu, and I can't quit to reopen in safe mode

-I am on a Mac.
-Firefox was behaving strangely, so I quit it.
-Upon attempting to reopen firefox, the situation occurred.
-Firefox is frozen.
-I can not get into the firefox menu. If I click on the firefox icon it still shows me the finder menu (no window appeared either. There are no outward signs firefox is open.)
-I can not open it in safe mode because I can not force quit it either.
-In the force quit menu it says firefox open, but nothing happens when I attempt to force quit it.
-I got no error message.
-In other words, Firefox is totally unresponsive. I can neither interact with it or force quit it.
To the solution...
-Upon research I believe its a problem with my theme, but I repeat I can not open firefox in safe mode.
-As I said, it says firefox is open but I can not interact with it.
-I can not restart my computer because it says firefox is open.
-I can not delete firefox because it says firefox is open.
I am posting this from Safari.
Please help, and thank you in advance.

<blockquote>
With a Finder window open, are you able to force quit Firefox by selecting the Apple menu > Force Quit > Firefox?
There are another couple of way you can start Firefox in Safe Mode: one is to hold down the "Option" key when you click Firefox in the dock. The other is to run the following command in a Terminal window:
<pre>/Applications/Firefox.app/Contents/MacOS/firefox-bin -safe-mode</pre>
Terminal.app can be found in Applications > Utilities. Just paste in the line above and hit the enter key.

The Terminal command worked like a charm, thanks.

I have two apple ID, and I can't switch between them, although I change to my old ID, and it remains in the new ID, and I can't update to old purchases I did with the old id.

I already did according to your suggestion (sign in and sign out) and the id remain on the new one.
Is there something more affective?

I cannot log onto the App Store, the page appears when I call it from the dock or the Apple menu and I can call the log-in box from the menu bar, but on signing in the spinning icon just keeps spinning,(not the beachball). Using 10.6.7 and up-to-date on all software. Any suggestions?

Could be a third party app preventing you from being able to login.
Mac App Store: Sign in sheet does not appear, or does not accept typed text
If it's not a third party issue, follow the instructions here.
Quit the MAS if it's open.
Open a Finder window. Select your Home folder in the Sidebar on the left then open the Library folder then the Caches folder.
Move the com.apple.appstore and the com.apple.storeagent files from the Caches folder to the Trash
From the same Library folder open the Preferences folder.
Move these files Preferences folder to the Trash: com.apple.appstore.plist and com.apple.storeagent.plist
Same Library folder open the Cookies folder. Move the com.apple.appstore.plist file from the Cookies folder to the Trash.
Relaunch the MAS.

Firefox 4 will not let me keep my bookmarks listed on the side bar. I can open them there but once I click somewhere else they go away.

Firefox 4 will not let me keep my bookmarks listed on the side bar. I can open them there but once I click somewhere else they go away. On previous Firefox versions I could display my bookmark folders down the left side of my screen and just leave them there, accessing saved bookmarks when I needed to. Now with FF4 I can open a vertical column of my bookmark folders by clicking on bookmarks in the navigation bar but this won't stay there; if I click elsewhere they disappear. I could put a bookmark toolbar on my screen but this takes up more vertical space. I have lots of horizontal space that's unused. How can I go back to the display of bookmarks in previous versions?

You can fix that by going to View -> Sidebar and click on Bookmarks.
Or you could simply use a shortcut
''control + B''

Mac user OS 10.6.8 Firefox 6.0.2. Click the Firefox icon in dock, program does not open new window. Type cmd+N to open new window, cmd+T to open new tab or cmd+L to enter URL, nothing happens. What causes this, and what can be done?

It's strange. The problem apparently resolved itself after I ran TechTool on it. When I clicked on Firefox last night, I had no problem opening a window. Thanks for your help. (As to your previous post, the focus was on Firefox and neither the speed keys nor the menu bar would open a window or tab of allow me to enter a URL to open a window. Strange!)

If you followed these instructions and you were unable to enter recovery mode, I'm still leaning toward a hardware problem. Also, since you have IOS-7, read this. It might help.

I just got the new itunes and I can open itunes and see my music but whenI try and go to the itunes store it just loads to a white page. I try and refresh and go to the home page and nothing happens. I can sign into my account and the tabs for the itunes store pop up like they normally would when browsing the itunes store but when I click on one of them, it is a blank page. Is there a setting I need to change? Does it just take an extremely long time to load? Please help!!

Hi MrJavonte15,
If you are having issues installing iTunes on your Windows machine, you may want to take a look at the following article:

If you have previously installed iTunes and continue to have issues, you may want to remove and reinstall iTunes:

Hello there, lgi00.
It can be so perplexing getting error messages when we are just beginning to launch a program. There is a pretty in depth Knowledge Base article that dives into many of the meanings to particular error numbers. See here:
iTunes: Advanced iTunes Store troubleshooting
http://support.apple.com/kb/TS3297
Under "Specific Conditions and Alert Messages: (Mac OS X / Windows)" there is the following explanation and guidelines to getting that issue resolved:
"Error 3001," "-42110," or "5103"
This alert is related to iTunes Store movie rentals and authorization issues.
Make sure you are using the most recent version of iTunes and QuickTime. They both can be downloaded free of charge.
If your iTunes is up to date, remove the SC Info folder.
Thanks for reaching out to the Apple Support Communities for finding an answer to your question.
Cheers,
