Can't open firefox after download. What's up with that?

Two weeks ago Firefox quit downloading attachments. Tried every online fix I could find and nothing worked. I uninstalled and installed the latest version. Program seems to download and it installs an icon on the toolbar but when you click on the icon nothing happens. I don't have time at work to debug a defective product. What a colossal waste of time. Why must software companies continue to dick with something that works perfectly and make it more and more complicated and unusable. I hate Internet Explorer but at least it works.

hello dowens, since this can sometimes be caused by malware active on a system, please run a scan with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes], [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] & [http://www.microsoft.com/security/scanner/default.aspx microsoft safety scanner].

I can't open firefox after ATTEMPTING to update

I was prompted to do an automatic update or uversion update, not sure which. I did, as usual, and when I came back to the computer, it stated, as usual, that Firefox needed to restart, so I closed it, and it attempted to reopen the browswer. I could see part of my toolbars adn the words on my desktop background, but no actual browser window, with the yahoo screen or toolbar tabs, etc. I could blindly click, and assume I hit a button that said "Close" or "OK". I think it was telling me the software update failed. It closes, tries to open up again, I see the "well, this is embarassing," but still no browser screen. It repeatedly does this close/open until I just close it, because the actual window never opens. I started using IE and attempted to update firefox version from the mozilla website, but it won't happen. I followed forum topics related to the above issues, but they require making changes through the Firefox window, which now (the next day) will not open at all. I want to uninstall and reinstall, but I don't want to lose my bookmark profile in Firefox. I also attempted two failed tries at connecting to a livechat, which got me down to #1 then informed me it was unable to connect. Lastly, even using my IE window, when viewing forum topics, lines overlap and make it hard to read the postings. This is somewhat similar to the words showng up on m background all jumbled, but not in an actual browser window.

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
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.
You can initially skip the step to create a new profile, that may not necessary for this issue.

Can't open firefox after upgrading to the latest version. All programmes affected, basically nothing works and it's driving me mad!

Having updated firefox, it does not work. After an hour or so to try and open firefox, it says firefox has crashed and gives option to restart or quit.
Same with internet explorer and chrome - no response. After about an hour, excel finally opened but so slow to be able to do anything.
Also noticed a message bottom right corner of screen saying this version of windows is not authentic. I have windows 7 and it is legitimate and have not seen this message before.
I have read lots on the internet but nothing seems to match my problem if nothing working. I am unable to change settings or look at set up of any programmes because I cannot get in to them.....
Any ideas would be so gratefully relieved please!!
Thank you in advance,

Start your '''Computer''' in safe mode. Then start Firefox. Try '''Safe''' web sites.
Starting The Computer In Safe Mode;
If running, turn your computer off.
Remove any disks and thumb drives that are in your hard drives or ports.
Now start your computer but also;
'''Windows; '''Press the <F8> key repeatedly.
'''Mac: '''Hold down the Shift key.
'''Linux; '''Using the command line, Linux/Unix computers can be booted
into various run levels that determine which resources are loaded.
For example, "runlevel 1" is typically the equivalent to Windows and
Mac safe modes.
* Source; '''[http://encyclopedia2.thefreedictionary.com/Linux+Safe+Mode Safe Mode; Free Online Encyclopedia]'''
When the '''Boot''' menu is displayed, release the key you were pressing.
You must now choose what mode to use. The most used are;
* Safe Mode; The computer runs with only a minimum set of programs.

Can't open firefox since downloading 5.0

I can open internet explorer; but since downloading firefox 5.0, I can't open it.

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.

Can't open firefox after setup and transfer

I transfered applications and files from my old imac to new macbook. Also copied my firefox and thunderbird profiles. Thunderbird email works fine. But, when I try to open firefox, I get this message: "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." No other copy of Firefox is open and I have uninstalled and reinstalled Firefox, but no luck. What in Leopard would cause this? No problem with Tiger...
Thanks, Rich

Hi,
Have you tried some of the suggestions here?

I'd recommend trying to launch it in safe-mode and see if you get any error messages.

Can't open Safari after downloading update this morning

Macbook pro, OSX Mavericks
Can't open Safari. Did an Apple update this morning and when i click on Safari, it just bounces. won't open

If you installed "CleanMyMac," the instructions for removing it are linked to my last comment. If it's something else, see below. If you don't know what you installed, ask for instructions.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

Unable to open firefox after download

I'm using a netbook with linux and firefox 2. I tried to download the newest version of Firefox, but it will not open. It says to change the helper application in preferences, but I don't know what that is. I need to upgrade my system because of security issues. Please Help!!!!

The version of Xandros Linux ''(from early 2007)'' that Asus was using on theEeePC doesn't have the GTK package needed to run Firefox 3+ versions, you need to update it. See these: <br />
http://forum.eeeuser.com/viewtopic.php?id=41815 <br />
http://wiki.eeeuser.com/howto:installfirefox3?s=firefox <br />
I am not aware any support articles about installing a version of Firefox newer than Firefox 3.0, although I read somewhere that if Firefox 3.0 worked, Firefox 3.5 would. But 3.5 is an unsupported version nowadays, you need Firefox 3.6.x at least.
I quit keeping track of the upgrade stuff about Xandros Linux because I installed a much newer Linux distro on my EeePC 900A in 2010. This is what I replaced it with: <br />

Create a new profile as a test to check if your current profile is causing the problems.
See Basic Troubleshooting: Make a new profile:
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

TS2363 Help can't open iTunes after download

I was able to download iTunes, but when I click on it I receive: Do you want to allow the following program to make changes? Program name Apple. When I select Yes, nothing happens. Any suggestions?

I am having the same issue. I was able to use iTunes to rent a movie, watch the movie, and since then, it shuts down less than 10 seconds after start up. Is there something wrong with the newest version of iTunes?
Can anyone tell me why iTunes is shutting down automatically and what can i do to fix it?

Can't open itunes after downloading latest update

After installing latest ITunes update, the ITunes Store doesn't open. Additionally, the Apple Device Manager program tries to run in the background consuming 50% of my CPU while never doing anything. I have tried the Netsh Winsock reset, and I have tried removing all the Apple programs (in order) after updating Windows. Actully I have tried both things multiple times over the past few weeks, and yet I still have the same problem. ITunes Store does nothing, and I have to end the process for Apple Device Manager. I have tried to remove the device manager program, but it still locks out the store. I have tried going to a restore point only to find that the Library file is not recognizable.
I am not sure if it is an issue, but the latest download (10.5) mentions 64 Bit, while my windows 7 operating system is a 32 bit (not sure what that means, but thought I would throw it out there).
Any other suggestions are deeply appreciated!

Just to point out that there is another thread on this subject and Apple are on the case:
