System FreezeFollow

I checked around and didn't see anything about this. I have been getting odd freezes here lately. It is happening everytime I am in Firefox browsing around the net. I checked my event viewer in safe mode and there wasn't any clues to what happened. I also ran Hijack This and it came up clean as well. Anyone have any thoughts on this?

Firefox version: Gecko/2008070208 Firefox/3.0.1
Addons: NoScript, AdBlock, FlashBlock

OS: Windows XP SP3
A/V: Windows One Care (going to be switching to AntiVir within the next 3 months)

System:
MSI 690G Mainboard (cant remember model off the top of my head)
AMD 64 X2 4600+ 2mb Cache
2x 1024mb (2048mb) DDR-2 800mhz Corsair XMS2 (I Think) (Confirmed by MSI to work with my system)

I am also using built-in sound. Provider is RealTek

So far it has only occured while using FF.

Eh its still sort of new... less than a year old.
I haven't tried re-installing FF yet. I am probably going to reformat my system anyways. I tend to collect alot of junk over a long period of time and every once in a blue moon the system needs a good recycling lol.

Sounds like you are being victim of random memory dump/retention issues which is common with some games and browsers.

I haven't heard of this with Firefox however, unless the items you are browsing are over addressing memory such as a flash games.

Hard to say with a sudden freeze, however after format I would keep track of what you are doing so when it does freeze you will know why.

I do know one instance where mine will freeze as well and that is when I am on a website which uses playlist.com embedded playlist player. Reason is does is because it keeps addressing memory even after you close Firefox or move on to another website.
