Software Update for Wyse X50M

 Software Update for Wyse X50M

I just bought a WYSE X50M thin client. I added the additional 2GB of memory and got a 32GB SD card for it. I would like to upgrade the Firefox browser. I tried to do this by going to Firefox and disabled the internet connection. I had to reset to default and reconnect with a physical Ethernet cable in order to re-establish a Wifi connection. I got this cool laptop on Tech for Less. I am an end user who has been using Windows and would like to learn more about Linux (SUSE Linux, in this case).

Is there a way of upgrading Firefox and adding Chrome and Opera without blowing up the machine? I am entering this entry (wirelessly through the built-in Wifi) with the WYSE X50M as we speak, so it works. I would also like to add a user account, as I am currently using the admin account, and based on my research, I have to be very careful, as the admin privileges are powerful enough to do something fatal.

Any help or guidance that anyone could provide would be appreciated.

Sincerely,
Bruce
