The only thing most of the people do on computer is surf the Internet. And for surfing Internet, the best browser, IMHO is Firefox (thankgod, someone made it). I use many plugins in firefox which make my life easier as well as help me in debugging my web applications.
I logged back into the windows (I didn’t want but there was no other way), and opened firefox. I already had FEBE plugin installed in firefox which is an awesome plugin which will back-up your bookmarks, extensions, themes, cookies, history etc, in one single archive. I backed up my profile and it took around 2 minutes to complete backup. I restarted and booted back in Ubuntu. I launched firefox, and installed FEBE and restored it by going to:
Tools menu -> FEBE -> Restore profile
I selected my backed up file.
Within 10-15 seconds, the profile was restored without any errors. I restarted my browser and found my firefox same as it was in windows.
