Firefox wont start or load but when I press ctl, alt, delete I see it running?

I upgraded Firefox. I worked for one night, the next night When I tried to open it it didnt work. I press ctl alt delete and noticed that it was running in the background but no window... IE and Chrome works fine... I do have internet.
I ran virus scans with no problems what so ever. Ran malwarebites and no issues. I have the windows firefall and disabaled it to see if maybe thats the problem, I also checked to see if Firefox had permission to pass the firewall and those were no issues.
Any Ideas.. please help.

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).

My MB pro doesn't recognize any start up discs. I have the flashing question mark, but when I press option/alt, I'm only prompted to start the internet recovery. Afterwards the Mac OS X Utilities pops up, but there's no start up disc?

Hello, sullivja.
Thank you for visiting Apple Support Communities.
Here is an article I would recommend going through when experiencing this issue.

Firefox needs to close and I can't load Firefox until I close it or reboot. Firefox appears not to be running and is not listed when I press "Ctrl-alt-delete."

Message says that Firefox needs to close. It does not appear to be running even when the "Taskmaster" (Ctrl-alt-delete) is displayed. The message says to close Firefox or reboot my computer. It happens constantly, even though I have closed Firefox, already. It appears to happen most often when I reach a page that refuses to respond to any mouse clicks, although, I can close the page (x). I, then, I cannot open Firefox until I reboot.

I bought about 350 musics on iTunes but when I click on the link to see the musics I bought, it shows only 204 musics

I bought about 350 musics on iTunes since I started using iPhone, but when I click on the link to see the items I have bought, iTunes shows me only 204 musics. This is a problem that annoys me because I have authorized a new device where I'd like to listen to all musics I have bought. I have already turned on the automatic transferences on the iTunes preferences so that all musics, books and apps are automatically transferred to the device. Even so, iTunes continues to show only 204 musics and I am not able to see all musics I have bought.
So, is there anything I'm missing here? Is there other local on iTunes where I could see all musics I have bought instead of only a subset of them?
Thanks in advance for any help,
Márcio

Just to better clarify what is happening: when I click on the link to show the musics I have bought on iTunes, musics that I had already bought some time ago do not appear anymore. So, I'm not able to download them anymore. For instance, in the set of the musics iTunes does not show me anymore there are 17 Peter Gabriel's musics. They are not shown and I cannot download them. So, how could I be able to download all musics I have bought instead of only 204 musics?
Thanks again

When I get to the login page on my macbook, I type in my password and it starts to load, but then the screen turns blue and it goes back to the login. What should I do?

I was having some problems with my mac, safari and itunes was freezing alot. I have to force shutdown and when I tried to start up again i get to the login page, type in my password and it starts to load, but then the screen turns blue for a few seconds and it goes back to the log in screen. What should I do?
Please Help!!

Somewhat similar problem:
Put in the password, hit enter, the screen goes blue for half a second, then goes back to login screen and carries on logging in as usual. Drives me mad. It doesn't happen with a fresh Lion installation, nor if booted into safe mode. On the machine in question it also happens to new user accounts.
I've removed all login items, including Startup Items and Launch Demons (pun intended) and Agents, I've compared system login plists with a fresh Lion installation - can't see differences. I've removed Little Snitch and PeerGuardian (no more third party kexts).
@Carolyn: I've done disk maintenance with DiskUtility and fsck and even DiskWarrior, cleaned caches, etc. etc.
Any ideas would be gratefully received.
Sorry for trying to hijack the thread (as it's not about Lion), but it seemed dead anyway.

Iv tryed this numerious times still keeps going back to pasword. Can not get any further. Tried restart holding shift key.. still nothing. What do i do?

Thank you for your help.
I couldnt get to the hard drive/ desktop. Soft login not even working. So i could not do any of that.
In the end i took it to Apple and its actually the hard drive on its way out. A common issue with that series of Mac. Funny seeing i dont use this mac much. However being 2.5 years old and out of warrently, Apple have recognise this issue with this series/ Model and installing a new hard drive at no cost.
Very luck and greatful. And not feeling so dumb that it was something i did or could troubleshoot myself.
Hope this helps others that it just might be your hard drive failing.

Whenever I try to upload photos into iPhoto, they load but when importing it just stops a picyure or two into it and then just sits there. I can't stop the import so I have to shut off my camera when it is importing and start again. Help?

As a test launch iPhoto with the Option key held down and create a new, test library. Tru importing from your camera to it and to see if the same problem persists. Does it?

My Mac won´t load. When I turn it on, I type the password, then it starts to load, but nothing happens. It gets stuck on the grey screen with the apple logo. I can´t go to an Apple store since I´m working in Bolivia. Thanks

Firefox wont start "XPCOM" message pops up, need my user and passwords!!??

My window 7 wasn't starting up properly so I did a system restore and now firefox wont start a message pops up stating "XPCOM" and I googled it and everything is telling to reinstall Firefox. I don't wont to reinstall it just yet because I need my passwords and username back. I cant find a solution on the forums either, or if there is I haven't found it or I simply didn't understood the solution itself. Please get back to me asap
thank you!

This usually happens because of a failed Firefox update that left you with a mixture of old and updated files in the Firefox program folder.
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
*Download the full Firefox installer and save the file to the desktop https://www.mozilla.org/en-US/firefox/all/
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
*Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*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.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
If you keep having problems then also create a new profile.

Stop Firefox from starting a new tab when a new window opens?

This might be answered, but I cannot find a solution. I will give a scenario for my issue.
I am on the UPS website and click a button to print a shipping label. This opens a new FireFox window, BUT... the new window defaults to a generic tab that ALWAYS opens in circumstances like this. It does NOT open to the tab with my label. The print menu opens, but I cannot switch to the tab with my shipping label. No right click to print either. So I have to go to another browser. Absolutely annoying.
So how can I STOP Firefox from starting this generic tab when a FireFox window opens? BTW, the tab has a search bar at the top and several boxes that I can click on for Facebook, Instagram, etc. Thanks!

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

Firefox remembers my passwords, etc but when I use the saved bookmark and activate it, the log in data does not display

firefox has remembered my passwords but when I click on the bookmark it opens gmail as an example but does not fill in my account name. When I fill it in the password is automatically entered..
== This happened ==
Every time Firefox opened

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" (on Mac: "Firefox > Quit")

Each time I open Firefox on my Mac, I am told to upgrade, but when I press install it simply runs on and on without completing.

Lately when I open Firefox, a dialog box comes up informing me that I should upgrade. But when I press install what I get is a process that goes on and on and never ends. I have had this happen several times and each time I have ended up closing the box and ending the process. This concerns me because I fear that at some point my version of Firefox will be so old that it will cease functioning. What can I do to insure that the newest version is installed. I have a Mac Book with OS 10.6.8.

This seems to have solved the problem. In any case I now have v. 35 instead of v. 14. Thank you.

Look at the highlighted copy of your Help > About Mozilla Firefox image attached below this message.
'''Reset general user-agent'''
-In Firefox, type '''about:config''' in the URL bar and press the Enter key.
-If you see the warning, accept it (promise to be careful).
-Filter = general.useragent.extra.firefox
-Right-click that preference and select Reset
-Then restart Firefox (File > Restart Firefox)

Installed the new Lightroom 5 CC on a Mac running the OX X Yosemite version 10.10.3 (14D136) Lightroom starts to load but within a 1/2 sec it closes. Is there a fix?

Installed the new Lightroom 5 CC on a Mac running the OX X Yosemite version 10.10.3 (14D136) Lightroom starts to load but within a 1/2 sec it closes. Is there a fix?

I had the same problem earlier today. Sign out of your account for CC in the Preferences panel, close the CC toolbar app. Then sign back in, and the download process might begin in earnest for you. Took me SIX HOURS to download this pig, and now it crashes continually. This software is not ready for release based on today's experience. Hopefully you will at least be able to get to the level of frustration I have arrived at, beyond the level of frustration you are currently stuck at trying to get it to work.I am on the same OS. Too bad Apple abandoned a pro level competitor to LR. Hopefully in the near future they will update Photos so that it competes well with LR.
