I've had to stop using Firefox because when I close it, and try to open it later, I get an error saying it's already running, so it won't start. I have to reboot the computer, or logout then re-login, which sucks. What's wrong?
Some versions of Firefox are known to have memory leaks. What this can mean -- and does mean, in your care -- is that Firefox is still partially loaded in RAM. All you must do is simply end the task.
On your keyboard, press CTRL + SHIFT + ESC at the same time, and the Windows task manager will open up.
- If Firefox shows up on the Applications tab, then select it, and then press the END TASK button. If you don't see it there, try the next suggestion...
- Go to the Processes tab and look for Firefox.exe, select it, and click the END PROCESS button. If you have a long list, sort it from A-Z by clicking on the category header.
Next, I suggest you visit www.GetFirefox.com
and download and then install the latest version of Firefox 3 (currently 3.0.10).
Hope that helps.
