Firefox won't open after update, black screen, beep and "do you want to allow program to make changes..."

Updated Firefox yesterday and now the program will not open on my desktop. Screen goes black for a second, issues a beep and then get box asking if I want to allow Firefox to make changes to my computer. Does not matter if I click yes or no, box disapears and nothing happens. Willing to remove and reload the program but hate to lose all my bookmarks.

'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "'Start in Safe Mode"''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''
'''''If it is good in the Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one.

I also have the same problem, but the Software Updates tool doesn't recognise that Quicktime is out of date. Have you tried downloading Quicktime 7.7 Leopard from http://support.apple.com/downloads/#quicktime as this worked for me...?

In Windows 7, Microsoft updated UAC in several ways. By default, UAC does not prompt when certain programs included with Windows make changes requiring elevated permissions. Other programs still trigger a UAC prompt. The strictness of UAC can be changed to either always prompt, or to never do so.

Firefox won't open after update/upgrade--how do I correct this?WinXP SP3

I got a message saying I should update/upgrade. I did AFTER SETTING RESTORE POINT. After this Firefox will not open (I have tried several ways). I went to restore point and restored. Still will not open. If I can't get it working I will look for another browser. I am now using IE and it is too slow. Thanks for help.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Firefox won't open after updates, unless I start it in safe mode

If Firefox has an update, and I let it update, it will not restart in regular windows. If I click the icon, nothing ever happens. This has been going on for awhile now, it is not a new problem for me. I'm running Windows 7.
The only way for me to fix this issue is to go into SAFE MODE and open Firefox from there, then it finishes the update and will let me load it in regular windows. It is extremely annoying, I have done fresh installs of the program multiple times, that doesn't help.
Any help would be appreciated.

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!

Firefox won't open after update

I recently upgraded to the latest version of Firefox, 3.6.6. Since then, I cannot open
the program. I have discarded the old version, and reloaded - still no luck.

Windows asks "Do you want the following program to make changes to this computer?" every time I start Firefox.

Neither my shortcuts nor my firefox.exe have Run As Administrator checked. And yet I get this prompt every time I start Firefox on my new laptop with Windows 7 Professional 64-bit.

unchecking "Run this program as an administrator" under the Compatibility tab in the properties of the program was my first guess....darn.
Ok I understand that this is only happening in Firefox. If you start it in safe mode does this still happen? This will tell you if its an add on or a changed configuration:[[Troubleshoot Firefox issues using Safe Mode]]

My itunes wont open everytime i open it it says "do you want the following program to make changes"i click yes then nothing happens

ive uninstalled it and everything it has asked. i have a sony vaio windows 7. i cant sync my phone and i need to ASAP.

That message can sometimes indicate compatibility mode issues.
Try the following document, only be sure that none of the boxes in the compatibility mode tab are checked (not just the compatibility mode box itself):

ITunes won't open after update; MacBook Pro, Mac OSX 10.6.8, iTunes version 11.1.5

iTunes won't open after update - help, please; MacBook Pro, Mac OSX 10.6.8, iTunes version 11.1.5.

i had a problem similar to yours and better yet, i have the fix for it. i downloaded maverick 4 months ago and was without itunes ever since. all itunes icon did was bounce. itunes would never open and whats more, is when i would try to update it, i would get a "thank you for downloading itunes!" page , but the download would never work. so i scoured the net for solves. nothing that worked. <4 months later> then last night i took a new approach. i decided even though maverick would not allow me to uninstall itunes, i would find a way to uninstall itunes. then i would reinstall back to 11.1.5 i was successful and heres what i did.
step one-
Back up your iTunes Library.itl file, found under ~/Music/iTunes
(even tho i didnt, i only had 3 artists in there at the time. and they didnt get erased but i advise you back up just in case.)
step two-
download itunes 10.7 from apple. i used this link Download it from Apple here
(i pulled the link from Aarons website (awesometast.com). you download 10.7 however you want but i used the link above and have had no issues).
although im not sure you need to do this step ( you may be able to download 11.1.5 itunes without 10.7, i did because i was following intructions from http://awesometoast.com/downgrading-to-itunes-10-7-from-itunes-11-on-osx/
step 3-
open Terminal
step 4-
enter in these 3 commands hitting return after each line. 1st line nothing seems to happen, 2nd line nothing seems to happen and 3rd line gives you a warning and requires password to continue. when i did it, my password didnt appear as i entered it and i hit return without looking, so i entered it in again, although im not sure i had to the 2nd time.
killall iTunes
killall "iTunes Helper"
sudo rm -rf /Applications/iTunes.app/
step 5-
drag off and dump the itunes icon (which now has the ? shadow in it) off your dock.
step 6-
install 10.7 itunes you downloaded earlier. (not sure if this part is neccesary. you may be able to just download 11.1.5 but i downloaded 10.7 because i was following Aarons steps.) itunes now works.
step 7-
go to apple and update to 11.1.5 itunes. install it. open it and you have itunes 11.1.5 in perfect working order. assuming you have a decent internet speed for the downloads, the whole process takes very little time.
with those steps above, you can solve itunes just bouncing and not launching issues and also the "thank you for downloading" and nothing downloads issue. enjoy. also i would like to give a shout out to http://awesometoast.com and thank Aaron for the knowledge that enabled me to get itunes back into my life.

How come my apps won't open after updating to ios5

how come my apps won't open after updating to ios5?

Thanks for the feedback. This is a custom enterprise application. So there is not an update yet. It will take our developer a little time to get it IOS 5 compatiable. So unless I can change the IOS we can't use application until we get upgrade of the custom app.

Cant get itunes to open after update. have uninstalled and reinstalled 3 times

Cannot get itunes to open after updating. Have uninstalled and reinstalled 3 times asper itunes instructions.

Okay. That's got the most common (current) possibility ruled out.
There's a lot of stuff that might be on the table still, though.
In the course of your troubleshooting to date, have you worked through the following document?

[SOLVED] Firefox won't open after restart..Until I updated everything

When I start my computer or reboot Firefox won't open unless I keep clicking the icon. I have it pinned to the task bar and it's set as default. when I click the icon it glows orange but then fades back to clear. sometimes as many as 15 - 20 times before it starts. I clean the temporary files every day with CCleaner. I'm not that computer smart but I haven't changed any settings and it was working perfectly until a few days ago. Once it opens I have o problems opening it and closing it
UPDATE:
I disabled the Facebook video call plug in updated all my Firefox stuff and it opened first try

Thank you Alice It took me two years to get Firefox looking exactly how I wanted it. I'm not very good with computers. I thought I would have to start over. The strange thing is there was no indication of a problem. It just wouldn't open. Skype kept crashing my computer so I followed their instructions on removing everything in the registry. I remembered something about Facebook video chat being through Skype so it just made sense to disable it. I didn't even know I had it until I updated the rest of the stuff. I don't know if that was it but Firefox is working and that's what matters.

Firefox won't open following update. Can't open Profile Mgr, even when using entire directory path in cmd line

I'm running Firefox on a Windows 7 machine. Firefox won't open following the latest update. I've read the help articles and it seems like I need to create a new profile because my settings have likely been corrupted. I'm unable to open Profile Mgr, even when using entire directory path in cmd line. I've tried the following commands in the command line:
firefox -p
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -p
Nothing happens with either command.
I'm also running Norton Internet Security. I read a help article Re Virtual Browsing features possibly causing a problem. The article said to check the virtualization setting in the internet security software and to clear the virtual cache. I went thru all of the settings menus in Norton Internet Security version 21.6.0.32 and I didn't see anything that looked like 'virtualization" settings, so I assumed that this doesn't apply to me.
If you have any ideas, I'd sure appreaciate your expertise!!

hello arcandl, when firefox isn't launching after you double-click on the shortcut this is sometimes also a sign of malware being active on a system.
you might want to try running a scan with some different other security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] which are specialised in removing adware and browser hijackers.

Firefox won't open after re-installing and can't remove from control panel. What do I do?

After a storm and short power failure, I started having trouble with certain sites loading, and pages moving slower. I emptied my cache and defragged and ran total virus/ malware scan, but still had problem. (Pages loaded fine on AOL) I decided to uninstall Firefox and re-install to help fix problem. I did this, and now Firefox won't open, no matter if I double click, right click (open), or go through "all programs". I tried to uninstall and re-install again, but now I can't get it to respond through my control panel, either.

Try the procedures in the [[Firefox will not start]] article.
