Feedback from some buyers: Every time I open Mozilla Firefox, it asks for an administrator account and password, but he doesn't know what password we've set.
In fact, our technicians didn't set any password for Windows OS, this problem comes from the automatic update of Mozilla Firefox, many Firefox users are crazy about this problem, here is the solution we found on the Internet, only three simple steps to help you solve the problem:
1. Save installation file on your harddisk
2. Right click on mouse
3. Execute (file) as administrator
For Ubuntu OS, mostly we set password 123456.
