Firefox won't open on my laptop. Need help?

[Jessica Ray]

I just turned my laptop on and tried to go on Firefox, but when I double clicked it wouldn't open. It worked yesterday, so I don't know what the problem is. I can't restart Firefox because it won't open. Nothing comes up when I click on the icon. I'm having to use Internet Explorer until I can resolve the issue. What can I do to get Firefox to work again?

Start Performance Monitor. Kill all instances of Firefox. Reboot computer.
Start Firefox again.

You can try rebooting, and running Firefox with -safe-mode -no-remote.
firefox -safe-mode -no-remote
It'll ask you something about disabling plugins, etc... answer carefully.
I think there's also some trick where you can start firefox with one of (ctrl, alt, shift, or win). I don't remember which one.
If your desperate, you can try deleting(or moving elsewhere) your Firefox profile.

First again restart your computer. If it doesn't workyou should uninstall your firefox and then again install firefox. It might be work. I think there is no need to reboot your computer.
