Firefox 6 has crashed, and corrupted a script file in Applications Data. The result , everytime i try and start Firefox, it says its already running, but it isnt. I have tried rebooting system, removing firefox ,reinstalling and still the problem exists.

It would appear that the corrupted script files are sessionstore.js or prefs.js.
these i found in Application Data/Mozilla/Firefox/Profiles/2xewu6aw.default folder

Firefox is already running but is not responding

'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox SafeMode is a diagnostic mode that disables extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.

If the problem does not occur in Safe-mode then disable all of your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You have to close and restart Firefox after each change via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Firefox won't open external links (from other programs), says its already running but not responding.

I'm having this problem, everytime i click a link on other program, like the program's link on the about tab, or a youtube link on Live Messenger, it won't open, a dialog pops up saying firefox is already running and not responding, but it is there, and working.
If it matters, i have the "beta" tab preview enabled on the windows 7 toolbar.

You're welcome

When trying to open an external link like updating a program firefox says its already running but is not responding how do I fix this?

Basically when I try to update Ccleaner or any other program tries to open a link it shows this error message. Like when I try to start BF3 from origin It shows the error message so I have to open battlelog by typing it into the browser. I dont recall me having this issue on my windows 7 64 bit laptop, but on my windows 7 32 bit desktop I have the problem. Any and all help is appreciated.

Make sure that you do not start Firefox with the -no-remote switch or have set the environment variable MOZ_NO_REMOTE=1 (Control Panel > System > Advanced > Environment variables).

Same problem as well as the network failure. Apple Care was suggesting a full reinstall and I declined. I thought it worked once but I can't be sure ... it might have been Skype which works perfectly.

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles. 
NOTE: Establish a habit of exiting/closing Firefox with Firefox button > Exit or File > Exit to allow an orderly shutdown of Firefox and closing of all of the files that Firefox has open.

When I close firefox and put my computer to sleep, the next day try to run firefox and it says its already running and I have to close it first; I have to ctrl+alt+delete to end the process and THEN start firefox.

The only other way to avoid this problem is to fully shutdown, or restart my computer.

There are other things that need attention.

HT202159 How do you reinstall an app that says its already installed but just sitting on my launch pad with a blank download bar underneath I can't reset it or delete it ?

My son has downloaded batman lego but it just sits on the desktop with a white box underneath and nothing happening
In the app store it is saying it has already been installed
We cant delete it in this stage and its not loading either any ideas would be great

First check your Applications folder to see if the app was installled there.
If not, from the App Store menu bar top of your screen click Store > Check for Unfinished Downloads.
If that doesn't help, try re downloading the app.
How to re download apps from the Mac App Store:
Open the App Store. From the menu bar click Store > Sign In
Click Purchases from the top of the App Store window.
Select which apps you want to re download. Then right or control click where you see Installed then click Install.
Make sure and use the same Apple ID used for the original download.
If you hae anti virus software installed, you may need to disable that before downloading apps.

Unable to work with songs. Says computer is not authorized, it is. Have tried deauthorizing and then reauthorizing, that works, but still get the msg that computer is not authorized. What to do? Thanks!

I have an older pc with itune songs on it. Trying to burn to disk. Tells me that the computer is not authorized to do this, it is. Have tried de-authorizing it and re-authorizing it and I'm able to do that. Then if I try to authorize it, it says it already is, but still won't allow me to work with my songs, still says not authorized. The songs I'm trying to burn were purchased from the itunes store, but don't show up on my purchased songs on my new iMac, not sure how to find them. Any ideas? Thanks!

Thanks for trying to help!
Tried it without much success though.
Looked good at first. I was able to unauthorize it and after rebooting all I went in under "store" and authorized it again, witch it did without a hassle.
But, when I had restarted everything again and tried to sync with me iPhone I still got "Part of the programs in the iTunes library, for instance 'yadda-yadda-app' was not installed on the iPhone unit 'The name of my iPhone' because you are not authorized for them on this computer. You can authorize this computer for purchases by choosing store - Authorize this computer"
(Translation to english might include minor errors...
So... Any other ideas on how to sync my iPhone with my iTunes?
(Oh, and my iPhone has never been jailbroken or anything like that.)

HOW DO YOU TURN OFF "FIREFOX PREVENTED THIS PAGE FROM AUTOMATICALLY RELOADING". I did the "see Advanced - General - Accessiblity. and still having problems

HOW DO YOU TURN OFF "FIREFOX PREVENTED THIS PAGE FROM AUTOMATICALLY RELOADING". I did perform the "see Advanced - General - Accessibility. It worked for me and my "user" site (don't know how to say my site) and still having problems with my wife's. I have gone to OPTIONS → GONE TO → ADVANCE and CLICKED THE LINE → ""Warn me when websites try to redirect or reload the page…""
This did not rememdy the problem. I did try to get on the other site suggested
http://kb.mozillazine.org/Accessibility.blockautorefresh
but got a 404 error...
I have googled the "ff prevented...." and after a number of hours searching I still have not found a fix...
REALLY HOPE SOMEONE CAN HELP ME....
JM

You should still disable this setting:
*Firefox > Options/Preferences > Advanced > General : Accessibility : [ ] "Warn me when web sites try to redirect or reload the page"
The setting in "Options > Advanced > General" is meant as an accessibility feature, as you can see by the label of that section, so that people with disabilities or people who use screen readers do not get confused and is not meant as a safety protection to stop redirecting.
What is the value of the accessibility.blockautorefresh pref on the about:config page?
*http://kb.mozillazine.org/accessibility.blockautorefresh
If you have problems with preferences, see:
*http://kb.mozillazine.org/Preferences_not_saved
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

When I try to start Firefox, I get a message that it is already running, but not responding and that I should close it before trying to run another Firefox. But I cannot find a way to close Firefox program that is not running as far as I can see. I tried uninstalling and reinstalling Firefox, but that did not work. I've tried various other things, but no luck. I thought programs should stop when the computer is turned off, but that didn't work either.
