I tested the program and found no problem using it. Using your file explorer, go to a directory of your choosing.<br /> (Not the desk top)<br /> Create a new file and call it '''KillFirefox.bat''' or whatever you want. Note; this is a '''BAT''' file.<br /> Open the file with a file editor, and copy everything below into it (after the ========= of course).<br /> Save the file. Now, use the file explorer, right click the new program, and select<br /> '''Create A Shortcut'''. Then move the shortcut to the desk top. Place it somewhere on the screen<br /> so that if Firefox locks up, you can still reach the shortcut.<BR><BR><br /> If you want more information about Taskkill, open a DOS window, and type Taskkill /?<BR><BR><br /> '''WARNING ! ! !''' You will loose anything that has not been saved.<br /> <nowiki>==================================================================================</nowiki> <pre>TASKKILL /T /F /IM Firefox.exe exit TASKKILL [/S system [/U username [/P [password]]]] { [/FI filter] [/PID processid | /IM imagename] } [/T] [/F] Description: This tool is used to terminate tasks by process id (PID) or image name.
