Firefox 4 opens, then as soon as I move my cursor, it disappears.

I open Firefox 4 but as soon as I move my mouse, Firefox totally disappears. I'm using Windows XP and never had a problem before I upgraded (?) to Firefox 4.
When I looked there was no crash ID.

hello Fakusnamus, multiple other affected users have reported that this was an issue caused by malware on their pc.
please run a scan of your system with [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] and the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] as well.

PS CS5 Extended on Windows
When trying to use the clone stamp and/or healing brush as soon as I move the cursor from the toolbar over to the image I get an exact copy of the existing layer that moves around the window with the movement of the clone stamp/healing brush. This just started tonight. What's causing this weird behaviour?

What are the settings in Window > Clone Source?

Recently, when I opened a website (any website) with Firefox, it opens, then 'disappears' into the side of my screen. I can't get the webpage to display normally.

After years of problem-free browsing on the same computer, Firefox now opens up to the taskbar, then you can see the page move over to the right of the desktop, then disappear. Cannot get it to display in center of screen as normal.
This happened for the first time about a month ago. We uninstalled Firefox, updated to the most recent version and reinstalled.
All was well until yesterday. Doing it again.
IE works fine.

* Use Restore or Maximize in the right-click context menu of the Taskbar icon to set focus to the Firefox application if you do not see the Firefox window.
* Open the system menu via Alt+Space and see if you can move and resize that window.
If that works then close Firefox (File > Exit/Quit) to save that setting.

XP computer crashes when Firefox is open, then blames nVidia, but no blue screen appears.

XP Service Pack 3, with all updates
Firefox multiple versions, currently 15
nVidia 6200 with multiple versions of drivers
Deep Scan using Vipre with current updates, found no viruses.
Computer reboots unexpectedly, no blue screen, but on recovery, Windows reports there was a blue screen and nVidia caused it. However, without Firefox open, I've had no crashes. Sometimes Firefox can be open, but then crashes when one of several new tabs (sites) are opened, but cannot identify what site might be causing it.

Are you experiencing this issue with another browser? Can you update to the newest version at http://getfirefox.com ?
Also you may have a virus -
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try some of the following programs to scan for malware:

The first time I click on Firefox,it opens then a box says trying to close ,and it closes no matter what I do.I must open Firefox twice before I can use it.

that's it.

Ga naar C/Windows maak er een nieuwe map aan, bv Program files Fientjefien.Ga vervolgens naar Program files of Program files (x86) knip de map Mozilla Firefox en plak die in je nieuwe map Program files Fientjefien. Dus gewoon de Mozilla map verhuizen.

Firefox keeps opening offscreen. I used the move function to get it back onscreen but everytime i reboot it happens again. Is there some setting I can change?

I have 2 displays hooked up, a monitor and my TV(which is usually off). When I hover over the Firefox icon on the taskbar I can see Firefox and the tabs that are open but when I click on them, click restore or maximize nothing happens. i was able to get it back using the move command and somehow either using the arrow keys or moving my mouse I was able to drag the window onto a visible area of my monitor. Is there some setting I need to change so that I don't have to do this every time I reboot? I'm running Windows 8.1. Thanks in advance for any advice.

Firefox stores the last window position in a settings file that can occasionally become corrupted. You could try removing that file and see whether Firefox correctly identifies your primary monitor. Here's how:
Open your current Firefox settings (AKA Firefox profile) folder using either
* "3-bar" menu button > "?" button > Troubleshooting Information
* (menu bar) Help > Troubleshooting Information
In the first table on the page, click the "Show Folder" button to open a new window showing your currently active settings files.
Leaving that window open, switch back to Firefox and Exit, either:
* "3-bar" menu button > "power" button
* (menu bar) File > Exit
Pause while Firefox finishes its cleanup, then rename '''localstore.rdf''' to something like localstore.old
Start Firefox back up again. Is the window visible?

When I download files from the internet, it shows the file downloading in the download box, but then as soon as it's done it just disappears. How can I fix this?

This has been happening for several weeks.

It sounds like perhaps the file doesn't have an extension that the system recognizes. Is this all files, or just one specific one, and if so, which? What is the name (and extension, if it has one) of the downloaded file? What kind of file do you *expect* it to be? (PDF, or whatever). Renaming a file with the appropriate extension can often fix that kind of problem.

When I open firefox it opens in a extremely small size. How do I fix this so it opens in full screen?

Firefox opens in an extremely small size when I open it. I tried to maximize it and restart. Nothing fixes it. How do I fix this problem? It is driving me nuts.

To make it open at a nice size, make sure you have only one Firefox window open, then un-maximize it (which should make it small again), then resize the window '''by dragging the corners''' ('''not''' using the maximize button) to make it whatever size you like. Close the window and it should then start back up at the same large size.
The same trick should work with any Windows program that opens in an annoyingly small window :)

Try to create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

How can i do solve this error plz plz plz plz help me out what you say troubleshooting,error or issue.'''

Did you perform a Firefox Reset either by clicking the button on the Help > Troubleshooting Information page or via the Safe mode start window?
You may have gotten the Safe Mode start window as the result of not being able to start Firefox more than once after crashes.
See:
*http://kb.mozillazine.org/Firefox_crashes
*https://support.mozilla.org/kb/Firefox+crashes
If you have submitted crash reports then please post the IDs of one or more crash reports that have this format:
*bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
You can find the IDs of the submitted crash reports on the about:crashes page.
*You can open the about:crashes page via the location bar, like you open a website.
See:
*http://kb.mozillazine.org/Mozilla_Crash_Reporter

If you can't open Firefox then see:
*http://kb.mozillazine.org/Mozilla_Crash_Reporter#Location_of_crash_reports
*http://kb.mozillazine.org/Mozilla_Crash_Reporter#Viewing_crash_reports
"Reset" creates a new default profile with a time stamp appended to identify it and tries to recover settings like bookmarks and history and passwords and cookies and auto-fill data from the old profile, but you lose data like extensions and other customizations.
*http://kb.mozillazine.org/Profile_folder_-_Firefox
Firefox 15+ versions will move the old profile folder to an "Old Firefox Data-##" folder on the Desktop that gets a number appended if you use reset more than once, so you can no longer use the profile manager to revert to the old profile.

Firefox 4 opens, then as soon as I move my cursor, it disappears.
