Computer checks out fine without firefox, but as soon as I add firefox sync it crashes. I just installed a new hd because my last one crashed as well. The laptop works well that I am trying to sync from. I just really must have my bookmarks and signins as I have an online business.

I'm writing this now from my laptop as my computer is doing a "necessary"chkdsk. I didn't see a crash report from firfefox and it crashed my computer real fast, but should windows give me one when it gets back up I will send it. I will likely have to remove firefox before windows can load normally(without internet because it crashed when opening a browser), but maybe in safe mode, as I used before to get back windows, it may give me a windows crash number, but I didn't see a number last time.

Oh, I did see in a blink of an eye during the crash dump, I think, something about "pool header"

Experimental Features


I am on my main computer now after reinstalling firefox without sync. It crashed again after trying to add some items so I did another un and in. Troubleshooting identified one thing: the driver for the graphics card not compatible with Aero Effects WDDM -something like that.wrong driver..so I searched all night for the correct driver. No program for driver install worked so I did windows update, again.

I just checked troubleshooter for Aero Effects and windows no longer sees a problem.

I've called the big guys to help you. Good luck.

Until this is fixed, disable sync on all devices.
