Lame firefox!!!!!

While I'm using my PC this evening, it suddently automatically shut off... and after I restart it... I found nothing was lost... except ALL my firefox bookmarks!!!!!

all the bookmarks I've kept is lost!!!! damn it! but luckily I made a backup of it... but it's one month before since I did the bookmark backup... so I lost lots of websites where I need to re-surf to recover them... haih......
