Uninstalled Firefox using Revo Uninstaller (advanced mode) in Vista, and now Firefox will not run, period. No task in task manager. What dependencies did I screw up?

I wanted to reinstall Firefox to get rid of all the old Java libraries still installed. I uninstalled using Revo Uninstaller in Advanced mode, and I didn't bother checking what it did this time. I know firefox needs something to exist before it will start, otherwise I wouldn't be having this problem.
== This happened ==
Every time Firefox opened
== I uninstalled Firefox with Revo Uninstaller in Advanced Mode ==
== User Agent ==

Yes, it needs the user profile, I think. Granted you probably lost all your bookmarks and passwords and history and so on...
Go to your [http://support.mozilla.com/en-US/kb/Profiles profile folder] and delete it (or back it up, maybe there's stuff you can scavange from there).
Try to reinstall Firefox now. It should create a new profile.
And the Java stuff will still be there. It is uninstalled separately at your operating system's control panel, I believe. You can disable the plugins you don't want, too. Just go into Tools > Add-ons > Plugins.
And for future reference, if you uninstall Firefox and check the box that says to delete your private data too, it will clean every single trace of Firefox from your computer. This isn't some fishy software you download from a fishy site. Firefox is clean and safe to use :)

I upgraded to FF 3.6.10 and now FF will not run at all. (Safe Mode will.)

I upgraded to FF 3.6.10. I have tried opening/starting FF from the Start Menu, from the Desktop FF Icon, and from the Program Folders Mozilla folder.
When I try to run FF, it will not start. In the Task Manager, FF shows up in the list of Processes -- for 1 second or less, and then disappears.
FF Safe Mode, however, will run.

If you do not have the original install DVDs, use the Aperture Trial installer instead:
Try if this download link for the trial version still works: if yes, you can unlock it with your serial number:

I uninstalled Firefox once, reinstalled it and it ran. I had a problem so I did it again. Now it will not run and I get an error message saying that firefox is running and you can only run one at a time. I can't figure out what is running.

Because of a problem, I uninstalled Firefox once, reinstalled it and it ran. I had a problem so I uninstalled/reinstalled it again. Now it will not run. I get an error message saying that firefox is running and you can only run one at a time. I have uninstalled multiple times and can't figure out what is running. The is only one Firefox installed and it is not open. What does this mean and how do I fix it?

If you use ZoneAlarm Extreme Security then try to disable Virtualization.

The first time an iPhone is connected to iTunes that is used to sync with another iPhone or iOS device, you are prompted to transfer the backup for the other iPhone or iOS device or to set up the iPhone as a new iPhone.
The former does as provided - it transfers the backup for the other iPhone or iOS device to the iPhone replacing all data on the iPhone that is included with the backup being transferred. The latter does nothing allowing you to make your various selections for the iPhone sync preferences with iTunes.
This is designed to be done right away with a new iPhone.
If you don't have a backup for the iPhone with iTunes on your computer and don't have an iCloud backup that hasn't been updated since choosing to transfer the backup for your iPod Touch to the iPhone, the data that was on the iPhone is gone.

I am on windows 7 and I upgraded to 10.0.2 and now it will not open. I have removed firefox completely and uploaded it again and that did not work. So my latest attempt I removed firefox 10 again and uploaded the beta version and once again nothing.

I am on windows 7 and I upgraded to the newest verison of firefox and now it will not open. I have removed firefox completely and uploaded it again and that did not work. I then made sure it could get through my firewall and that did not work. So my latest attempt I removed firefox 10 again and uploaded the beta version hoping that would do it and once again nothing. It will not open at all. Please help - is there a live chat or a number to talk to someone at Firefox?

I think when uninstalling you may also have to choose (tick) to delete the preferences and other personal data like the bookmarks, stored passwords etc. to erase completely. If you are installing afresh, please try right-clicking on the file and '''Run as administrator''' to install. And when uninstalling, please also make sure choose to delete all data and also manually delete any '''Mozilla''', '''Mozilla Firefox''' or '''Firefox''' from %appdata%, %localappdata% and %programfiles%. You can open a location by typing for eg. %appdata% in the '''Run''' box (Windows key + R). You may also have to check the '''VirtualStore''' folder in %localappdata%. Files in the VirtualStore can be problematic. I think a clean installation may help.

Please note that using system restore would usually damage the Firefox installation.

I updated Firefox and now it will not open at all. The hourglass shows that it's working but then nothing. I went to add/remove and removed mozilla and reinstalled it and still the same thing. It worked fine before I updated.

I updated Firefox and now it will not open at all. The hourglass shows that it's working but then nothing. I went to add/remove and removed mozilla and reinstalled it and still the same thing. It worked fine before I updated. Now I can't even remove the program at all. Why is this happening?

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.com/kb/Safe+Mode
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
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

After a Firefox upgrade/update, your firewall may not recognize that new version and will not allow access to the internet; that is your firewall doing its job. You may need to
#close Firefox (Firefox button > Exit or File > Exit)
#remove permissions for Firefox from your firewall's programs list
#restart Firefox
#allow your firewall to detect the new version and give the permissions needed by your firewall for Firefox to access the internet.

I can no longer import pictures to my ibook (OSX version 10.6.8) using iphoto 09 version 8.1.2 and now get message that file is in an unrecognizable format. What is wrong? Same camera as before.

As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.

Run the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

Silverlight 5 WebBrowser Control - Is the SL5 WebBrowser control is set to work in IE7 mode only? I have a 3rd party web site i'm hosting and now they will not work with IE 7 Compatibility mode. Looks like this control can't detect I'm setup for IE 9.

Silverlight 5 WebBrowser Control - Is the SL5 WebBrowser control is set to work in IE7 mode only? I have a 3rd party web site I'm hosting and now they will not work with IE 7 Compatibility mode. Looks like this control can't detect I'm setup for IE 9. I'm
running IE 11 with registry hack for IE 9. I think the SL5 webbrowser control is set to work only in IE 7. can some one verify this or tell me how to set the WebBrowser control up to run either IE8, 9, 10 or 11? I have same issue with machines running IE 8
and above. This Silverlight 5 application is running out of browser with the elevated privileges (hack) and at test certificates install in proper stores. This application has been running for 2.5 years. Vender switch on some changes a couple days ago that
broke this application. Help!!

Hi,
It seems there is nothing to do with IE mode.
Please make sure your link still can be accessed.
The WebBrowser displays HTML content in applications running in a Silverlight 4 or later out-of-browser applications or in Silverlight 5 in-browser trusted applications only.

Welcome to the Apple Community.

Connect the micro USB cable to the Apple TV and to your computer.
Reconnect the power cable (only for Apple TV 3)
Open iTunes.
Select your Apple TV in the Source list, and then click Restore.

I have reset my ipad using General Reset Erase All Content and Settings. And now it will not boot. All i see on screen is the Apple logo. What do i do?

When you restore, you can restore to factory settings or to a backup. Restoring to factory settings removes everything and takes you back to out of the box status and you start all over again. Restoring from your backup will replace all of your app data, bookmarks, email settings and things like that. You still may need to sync all of your purchased apps and music, photos and so on back to the iPad.
I assume you want to restore from your backup to put all of you data back on the device so connect the iPad to your computer, launch iTunes, right click on the device name on the left side under the devices heading and select restore from backup. After you restore from your backup, make sure that you sync all of your other content with iTunes.

Installed Adobe dlm add-on and now Firfox will not open. I see the process starting in Task Manager but no window opens. Unistalled Firefox then re-installed but still no luck. HELP ME!

I installed Adobe dlm add-on and now Firefox will not open. I see the process starting in Task Manager but no window opens. Unistalled Firefox then re-installed but still no luck. HELP ME! I do not want to use IE! I presume it has something to do with Adobe DLM as ever since then it is not working.

I had this problem for a couple weeks as well and it was extremely frustrating considering we use firefox for all our company tasks. Here is the solution:
First of all if you have no bookmarks you want to save, then go directly to step 7. If you want to save your bookmarks first, then follow these steps.
1. Shut down the computer
2. Reboot and open firefox
3. Go to Task Manager, right click firefox.exe, and click END PROCESS TREE
4. WAIT 30 SECONDS! Then Double-click the shortcut to try and open firefox again
5.Repeat steps 3 and 4 until firefox finally opens (trust me, eventually it will)
6. Once it finally opens, backup your bookmarks,
7. Download a copy of firefox from there website
8. Uninstall from programs menu and make sure to check the box REMOVE ALL COMPONENTS
9. install the new copy and BOOM! it works
If it doesn't work, you're an idiot. If you don't want to reinstall firefox, then you're out of luck. Good Luck!
