Launching Firefox gets the Mozilla homepage not mine, why?

When I launch Firefox it goes directly to the mozilla start page as if I never used Firefox before. Everything is blank, no bookmark, no history, nothing. Why can't I go directly to my homepage? This frustrates me so much I have to go back to safari. I would use Firefox.

The user agent corruption looks like a consequence of Fast Browser Search (FBSMTWB) that has created a general.useragent.override pref.

Download a fresh Firefox copy and save the file to the desktop.
*Firefox 12.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded 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.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Firefox will not open at all. I only get the Mozilla Crash Reporter over and over.

After updating yesterday, Firefox will not open. I repeatedly get the Mozilla Crash Reporter. I've scanned my computer for malware, I've tried to open it in safe mode (it won't), I've completely uninstalled and reinstalled Mozilla, but nothing works. Each time I reinstall, I still get the Mozilla Crash Reporter. The program will not open at all.
I ran my crash ID. Here is the info: bp-eff196eb-ed21-45ee-83c6-e0fc42130123

hello, this crash is caused by Websense Endpoint security software that is running on the system. please try to install all the updates for this program that are available...

Can't launch firefox or the profile manager. Get an error that the profile is missing. Any ideas?

I have numerous users that are having this same issue. I cannot launch firefox or the profile manager. I have tried removing firefox and installing it again but get the same error. Any help would be greatly appreciated.

See:
*http://kb.mozillazine.org/Recovering_a_missing_profile
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.org/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.

As far as your UserAgent showing Firefox 3.0.11, see this:

I updated iTunes today (Windows). When I tried to launch, I get the message, ""The procedure entry point AVCFURLAssetInheritURIQueryComponentFromReferencingURIKey could not be located in the dynamic link library AVFoundationCF.dll".

I updated iTunes today (Windows). I restarted the computer but when I tried to launch, I get the message, ""The procedure entry point AVCFURLAssetInheritURIQueryComponentFromReferencingURIKey could not be located in the dynamic link library AVFoundationCF.dll".
I then did a new install of the latest iTunes version and got the same problem. No more iTunes.
HELP!!!

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

I upgraded my Yahoo IM and after it uploaded, my homepage went from Firefox to the Yahoo homepage and I cannot get the Firefox homepage to come up. I have tried to reinstall Firefox, but the Yahoo homepage still comes up. How can I get the yahoo page off and get the Firefox page back on?

Here are instructions to [[How to set the home page#w_restore-the-default-home-page|restore the default home page]].

Most of the time, when I try to load the home page, I get the message server not found - now I get this message and can't go anywhere

I have dial up - once I connect to the internet, I get the message server not found and am unable to go anywhere on the internet. This started trying to load my banks online site and started about a week ago. I've tried freeing popup blocker, gone through the settings with a bank IT specialist, tried to us IE which has resulted in a request for a cable and now no access to any website. Any suggestions appreciated. Thanks

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.

Running Windows XP service pack 3. Updated Firefox from 8.0 to 9.0. Now when Firefox opens "The URL is not valid and cannot be loaded" is displayed in a window and no home page appears. What's wrong?

Running Windows XP service pack 3. Updated Firefox from 8.0 to 9.0. Now when Firefox opens "The URL is not valid and cannot be loaded" is displayed in a window and no home page appears. What's wrong?

That issue can be caused by an extension that isn't working properly.
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.

I have a Macbook Pro 15" with Mountian Lion. I want to install an older game but I get the "Classic environment not supported" error. I see some reference to ACGI and Apache software that may solve the problem but it is not in my Utilities file. What to do??

The Classic game Risk II running in Sheepshaver on my Lion Mac Mini:
[click on images to enlarge]
Here is a post I recently assembled for another similar question:
With the newer Intel Macs, you have to run a Classic emulator such as SheepShaver, which requires you to extract the Mac ROMs from your older Classic Mac and then install Mac OS 9.
A related program is Chubby Bunny, which comes bundled with all of that included (google the term "Classic-On-Intel v 4.0.1 chubby bunny").
