Firefox browser won't open and doesn't show in task manager
All of my browsers will not open, but Firefox is my main browser. I've tried pretty much everything to get it to work (re-install, start in safe mode, entered ping 126.96.36.199 then www.firefox.com into the command box thing - did this with all the browsers- but they all come back with not recognised as an internal or external command, operable program or batch file) . It just won't launch, and does not appear in task manager at all. I'm at a loss for what to do. Please help!

What is your computer system and Firefox?
Type about:preferences#advanced<Enter> in the address bar.
Under Advanced, Select Network. Look for Configure How Firefox Connects and press the Settings button. If you are using a proxy, make sure those settings are correct. If there is no proxy, first use No Proxy. If there is a problem, then try System Proxy.
Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;
- Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
- Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
What version of Windows are you running?
To try starting Firefox without using its icon, you could use the Windows "run" dialog. Hold down the Windows key and press r to call that up. The type or paste
firefox.exe and press Enter to run it.
Do other programs start, such as Notepad.exe? If all EXE programs stop running, that can indicate bad registry settings caused by a malware infection.
