Hackers opening multiple tabs in seamonkey browser automatically

[webc]

Hackers are automatically opening multiple tabs in seamonkey browser, especially when the bsnl connection is used. Wifi has been disabled. How to prevent the opening of multiple tabs in the browser, and trace the hacker

When unwanted tabs are opened are you doing any particular action or visiting some website? Or is it fully random?
Did you tried to reinstall browser or use different profile?
Did you tried using different operating system?
Did you tried to disable all Seamonkey modules/extensions?
Which unwanted web sites are opened?
What about trying to use VPN or proxy.

when you use other connections, no unwanted tabs are opened?
