Web browser not opening

On clicking on my WEB BROWSER . no window is appearing , only a dialog box appearing with named "ALERT" any nothing else.
What is browser package name , which is by default in Solaris 10

Mozilla Firefox should be the one

i guess you are logged in via a graphical desktop? from there, open a shell and run `which mozilla`

if you get output like this (or similar), youre in luck

then just run

hopefully the browser window comes up. if not, post what happens.

Only post update 5. Prior to that it was still the mozilla suite.
