Firefox will not boot after shutdown

[seadragon1855]

Previous Firefox still works fine but now it makes me feel boredom

I still use Firefox 18 previously normal operation but often failed recently, I double-click, select Open does not open

But the removal is complete reset to normal, shutdown the same error. Do not know what my Firefox error??

You do know how to fix it help me.

Thank!

You need to upgrade your version. It's not even safe to use such out of date software.
