Firefox crashes

Hello, It's been three days since my firefox crashed and I think that I tried everything!

I was trying to emit WiFi with the cmd command "netsh wlan start hostednetwork", but I couldn't make it (I don't know if it's relevant). In the end, firefox crashed and when I tried to open it again, I received an error of "Firefox is already running" and "Your profile has been lost". Then, I rebooted my laptop and I got the same messages. I uninstall and install again, I created new profile, I deleted profile.ini... but always the same errors.

I have always a firefox.exe running in my task manager (even firefox is unistalled), and if I try to end it, it appears a "denegated access" message. I have even tried as an administrator but it's imposible. If it's unistalled, the process is a .tmp file located in the file /tobedeleted.

I also rebooted into "safe mode" and try to delete every file of Firefox (the files in %APPDATA% and in Program files) and when I reinstalled, it worked for 2 minutes and crashed again.

I don't know what else to do and I hope you can help me. Thank you very much in advance.
