take backup of your tabs and bookmarks in firefox

I was excited to figure out that its possible to take backup of my tabs, windows and bookmarks, basically my "profile" in firefox! Why? I usually keep many tabs and windows open, all for separate purpose and never close them... who knows when they will be helpful!

This is the link published by mozilla. The steps are quite simple too :)

Enjoy!
