Firefox/Vista Erros

Friday, May 18th, 2007 by | Filed Under: Using The Internet

Firefox/Vista Errors

A lot of faithful Firefox users have been presented with a lot of errors while using Firefox with the new operating system of Windows Vista. These intermittent errors can be very annoying, especially when you are right in the middle of editing a very important document with your favorite Web application, etc. So, today we are going to deal with two of the most frequent Firefox errors in Vista.

One goes like this: “The program must close to allow a previous installation attempt to continue. Please restart.”

This error comes up when you start Firefox and no matter how many times you restart it, there’s no change. You just keep getting this error and aren’t able to use the browser.

To get rid of this error, close Firefox down completely and open the Windows task manager by pressing Ctrl + Alt + Del. Once it opens up, under the Processes tab, look for a process named “xpicleanup.” If you find it in the list, just end it.

Next, open this folder: C:\Users\<your_username>\AppData\Local\VirtualStore\Program Files\Mozilla Firefox (start by double clicking the My Computer icon on your desktop, open the C: drive and so on). The “AppData” folder is hidden by default, so to view it, either enable the viewing of hidden files and folders by going to Organize Folder and Search Options, Folder Options, View tab, Show Hidden Files and Folders or simply go under the Start menu and type “%Appdata%” in the search box. Press Enter when you’re done.

Once you reach the folder, locate the file named “xpicleanup.dat” and delete it.

Now, start Firefox and it should work. However, in case the problem still persists, go to the task manager again and end any process by the name of “xpicleanup” or “Firefox.” Then go to the Firefox installation directory, which by default, is C:\program files\Mozilla Firefox. Again, locate any files by the name of “xpicleanup.dat” and delete them. This should solve the problem for good.

Another common error that Vista users get with Firefox reads like: “Error opening file for writing.” In this case, Firefox simply requires you to log in as an Administrator. To tackle this little issue, simply right click on the Firefox icon and choose “Run as Administrator.”

I hope these solutions will help all you Vista users who read the newsletter to avoid these pesky little Firefox errors!
