Clicking on Firefox Icon won't open Firefox anymore/ system says Firefox is unsafe

I was in Firefox last night. When I logged out of a gaming site and closed windows I could not reopen Firefox. I had to go back to Zoomtown today to get into the internet.

Sorry you are having problems. First of all try Fifrefox's safemode.
*[[Troubleshoot Firefox issues using Safe Mode]]
If that works post back for further advice.
Next step, if safe mode did not work.
First: Try a clean install, (you have had a none standard version installed previously) that involves deleting the program files. Then if necessary try troubleshooting by creating and using a clean empty Firefox profile.
See
* this recent post [/questions/940399#answer-377134]
* http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Clean_reinstall
Second: try a New Profile
*http://kb.mozillazine.org/Profile_Manager#Creating_a_new_profile
* this will be an additional profile, it is still worth backing up any existing or currently working profile on a regular basis
**[[Back up and restore information in Firefox profiles]]
* Until you are absolutely confident about the repercussions I suggest
** always use an empty folder when creating a new profile
** never delete or rename profiles, just disable or remove shortcuts
** after creating a new test profile open it and check for any addons or plugins that may be have been included by default

Firefox 4 won't open on my Mac; says it's not compatible with my system (Mac OS4)

I read the system requirements for Firefox 4. My mac should be compatible. I had Firefox 3.6? on my mac. Am running Mac OS 10.4.11. I downloaded Firefox 4; when I tried to install, it said there was a "newer" version of the software on my machine (but it is/was version 3.6) and asked if I still wanted to proceed. I said yes, thinking Version 4 would replace 3.6. Well, it did this. Now, Firefox is in my apps folder, but the icon has a / sign across it and the app won't open up. Just says it cannot open because it is not supported on this system.... Now what do I do? I can't go back to the 3.6 version because I can't find a version of it to download and I can't open 4. Help! How do I get Firefox back on my computer?

4.0 needs 10.5 and an Intel processor. 
http://www.mozilla.com/en-US/firefox/4.0/system-requirements/
For older Macs that aren't supported in Firefox 4.0, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .

After i install firefox on my computer, i click on it and it doesnt open up, it just says it loading up then it stop loading

after i install firefox on my computer, i click on it and it doesnt open up, it just says it loading up then it stop loading
== This happened ==
Every time Firefox opened
== i installed it ==
== User Agent ==
Opera/9.80 (Windows NT 6.0; U; en) Presto/2.5.24 Version/10.53

When you say "it just says it loading up" I assume that the window has appeared, and your start page is not loading.
Do you have any security software that might be getting in the way? Firewall? Anti-virus?

Hard Drive icon won't open and menu bar flashes off and on

All of a sudden, in the middle of the day, my eMac went haywire. I can launch apps and docs are one the desktop. But I cannot open the Hard Drive icon. If I double-click on it (or used Command-O from keyboard), the icon won't open. And when I attempt to open it, the Finder Menu Bar begins flashing off and on (vanishing, reappearing, vanishing) across the top of the screen. I haver rebooted, run disk utility to repair permissions, even booted from TechTools to run its diagnostics. But still no access to the Hard Drive icon. I logged out and logged in as a TEST user, and same thing happens even when logged in that way. Literally, this happened in an instant. One minute the eMac was fine, then this started. Anyone else seen this? -- david

If the problem exists in both your regular account and your Test account odds are that it is at the system level. You can try a Safe boot (hold down the shift key at startup) to see if there is a third party startup item or one of the optional Apple functions that is causing the problem. You could also boot from the installer disk and use the Disk Utility->Repair Disk function. If you have a utility such as Tiger Cache Cleaner which will do a deep cache clean you can also try that.

Some files in "DOCUMENTS" icon in dock won't open. Get msg saying You need a newer version of Pages to open this document." Have Pages 4.1 installed. Same files will open ok from Finder, Pages App. Recently sync'd with ipad2 (Pages) after iOS5 installed.

Some files in "DOCUMENTS" icon in dock won't open. Get msg saying "You need a newer version of Pages to open this document." Already have Pages 4.1 installed. Same files will open ok from Finder/Pages App./selected file. Prob not noted until recently after sync'd with ipad2 (Pages) when I installed iOS5. Anyone-- please?!

You have 2 versions of Pages on your Mac.
Pages 5.2 is in your Applications folder.
Pages '09/'08 is in your Applications/iWork folder.
You are alternately opening the wrong versions.
Pages '09/'08 can not open Pages 5 files and you will get the warning that you need a newer version.
Pages 5.2 can open Pages '09 files but may damage/alter them. It can not open Pages '08 files at all.
Older versions of Pages 5 can not open files from later versions of Pages 5.
Once opened and saved in Pages 5 the Pages '09 files can not be opened in Pages '09.
Anything that is saved to iCloud and opened in a newer version of Pages is also converted to Pages 5 files.
All Pages files no matter what version and incompatibility have the same extension .pages.
Pages 5 files are now only compatible with themselves on a very restricted set of hardware, software and Operating Systems and will not transfer correctly on any other server software than iCloud.
Apple has removed almost 100 features from Pages 5 and added many bugs:

Hello flarogue7
This issue means there is certain issue with your HOSTS file.
Just navigate to C:\Windows\System32\drivers\etc on your computer, rename the HOSTS file and try to install. It will install.

Help! Icons won't open

I have a problem recurring on and off where when I turn my computer on, none of the icons open. I have to manually shut it down with the button, Then, when I start up again there is often just a black screen, or the same thing happens where the icons won't open, or it starts a disc scan. So far, if I walk away and come back to it much later in the day, it will work again. Am wasting so much time, and I am am afraid one of these days it just won't be usable at all. I have a toshia satellite, just barely a year old, with windows 7 (which I loathe.)( Any suggestions? I have tried the geek squad and gotten nowhere.

Go to START/MSCONFIG and disable all startup programs (under the STARTUP tab) except your anti-virus. This is a possible error occuring from a memory leak in a background program, so this might assist. Please post results or any action you've taken in testing/resolving.

Why Facebook app icon won't open?

My iTunes won't open! It keeps saying 'The iTunes Library.itl is locked on a locked disk or you not have write permission for this file.' Please Help!

My iTunes won't open! It keeps saying 'The iTunes Library.itl is locked on a locked disk or you not have write permission for this file.' Please Help!

this may happen on external drives if:
The external drive was hotpluged (removed) without going the correct "eject" way
The iTunes library (database) got corrupted
First Aid for external drive
Close iTunes
Unmount (eject) external drive the right way.
Mount drive again
Go to Workplace -> right click external drive -> choose "clean up" This will force the filesystem to rescan the file structure of the drive and rebuilding the file system table and journaling file.
After the tool shows "done" (could last some time depending on size of drive) restart iTunes
If your iTunes library is on your internal drive, this may happen
The system was not shoot down correct, e.g. "pulled the plug"
The iTunes library (database) got corrupted
First Aid for internal hard drive
Close iTunes
Reboot system
Go to Workplace -> right click external drive -> choose "clean up"
After the tool shows "done" (could last some time depending on size of drive)
Reboot system, restart iTunes

Quicktime Desktop Icon won't open

I click on the QT icon on my desktop and it won't open the program, but if I click on a QT file, the program opens with no problem.
I just uninstalled QT and then reinstalled it, and I keep getting the same problem. Any help on this? Thanks.

Does the program open if you go "Start > All Programs > QuickTime > QuickTime Player"?
(Trying to get a feel for the full scope of the problem.)

My desktop icons won't open but I can open them from the finder thru the dock; how can I fix this? I run 10.5.1

I run 10.5.1 and I have been getting a blue screen on boot that takes forever before the screen icons pop up...then I can't open them by clicking on them even though I can do so thru the finder in the dock. Any ideas how to fix? I dumped a bunch of stuff my boot drive to free up space...I have aropund 130 out of 160 gig that's available.

Go to your Applications folder where you have installed these applications that will not open. Right-click, or two-finger tap (if enabled) the application icon. Choose open, and the application will launch. This is a one-time deal, as afterwards, that specific application will launch normally.
This is an Apple security mechanism. You can override this in System Preferences > General: Allow apps downloaded from: Anywhere. However, it is not set to Anywhere to protect you, and even I do not leave Anywhere permanently enabled. Only for those apps that I know are not in the App Store, and already know have this open behavior.
