Hello,
Today I came to school and started my firefox and to my surprise, I had lost everything :(. No "too many tabs", No "xmarks, No "stumble upon" and many more things. I was shocked to see all my precious tabs which are not important at all are lost.
I searched a little bit and got a little hint
So checked ~/.mozilla/firefox/

• ls ~/.mozilla/firefox/

Saw 3 profiles (folders) there, 2 were previous (which I was supposed to lose) and one newly created.
And a file called profiles.ini

• Open profiles.ini for editting (vi, nano, gedit etc)
• Modify the field "Path = " change it from .default (newly created) to one of previous profiles (you may want to copy and paste folder name if you have more than on .default folders.
• One more thing if you can't decide which .default you want to chose just explore that folder and you will see required plugins etc.
• If firefox is running restart it.

And you will have your previous settings :)
