Is Firefox still installed on your computer? You can call up the Windows "Run" dialog from the applications screen or by holding down the Windows key on the keyboard and tapping the R key.

In the Run dialog, type or paste this and press Enter:

firefox.exe

Will Firefox run?

why is there no phone number to call,please provide one.

Mozilla does not have the resources to provide call centres for one on one support by phone, chat, or email on desktop Firefox especially since it would be for free for a free product. Products that have one on one support are generally for paid for products like some antivirus clients for example.
