Firefox has become very unstable over the years, particularly with the unfortunately ubiquitously-necessary Java and Macromedia plugins.  I've had lots of browser crashes, a few BSODs and often a lot of lag and unresponsiveness.

Webmasters gripe about ad blockers, but most flash ads are super-bloated and buggy to the point of crashing Firefox a lot, and its even creeped in a bit to the same plugins on Chrome sadly, though nowhere near as bad as Firefox (and thus I tend to default to using Chrome).

Chrome's been my default for sometime now. Still have FF v24 and it seems stable. Last time I used it there were no problems even viewing pages here. 

Usermode software on modern versions of Windows cannot directly cause a BSOD. If it can, then that's a bug/vulnerability in the kernel or drivers. BSODs tend to pretty universally be due to driver bugs or hardware faults.

What kryo said.

I became quite adept at BSODs over the years....I could crash anything....usually by toying with shells...

I let the smoke out......once.

hehehe

not bsod. but my firefox has been crash happy for quite a while now (months?) .... maybe to do with that reloadplus.... or maybe something else entirely

Well, I ran complete and extensive memory checks on my PC, both system memory and video memory, and there were no errors at all. Since I reinstalled Firefox fresh yesterday I have noticed a lot of improvements and fixes in areas where I was having issues before. So I guess every so often it might be a good idea to uninstall it, run a registry cleaner, and then reinstall with the latest version rather than totally relying on updates. I also turned off the hardware acceleration and I have had no crashes or BSOD's since. I also turn off hardware acceleration in IE. Here's hoping all is well!

before to Standby or Hibernate the OS always close Firefox (my restart after the Standby is only lasting 20 seconds well spent)

daily check this page http://www.mozilla.org/en-US/plugincheck/ and keep all the plugins updated

and ... if you like the Tabs Previews resting on a Dock (autohide) use my new Stylish style http://userstyles.org/styles/94040/topsidebar-tabspreview-dock

BTW only on Firefox !

Thanks for the info frankell, I already keep all my add-ons up to date though. Not too sure about the dock, I am really basically a minimalist kinda guy. Nice looking though!

Myopia runs rampant through his genes....

OK, had another BSOD, and using the WhoCrashed software Jim recommended it showed it being caused by my video drivers. So then I rolled back the drivers and installed the latest drivers from nVidia for my GTX560 cards, turned on SLI, and then re-enabled hardware acceleration in Firefox and IE since that evidently wasn't it. Now we shall wait and see ...

Except I only got them using Firefox watching live streaming video, and got several of them per day.

Watching the same video streaming (from the same streaming sites) on Chrome, I did not incur BSODs.

I also am using Pale Moon x64 . I have Google also but it runs much slower than Pale Moon. Google sometimes does not load web pages correctly, but that is on my system, not everyone has same problem , Firefox in the past crashed quite a few times than I found Pale Moon and it runs flawlessly on my PC , but like I said before not everyone will have the same result on there PC. If your running 64bit you could try these Waterfox, Cyberfox, or maybe Nightly. I have tried them all and they seem to work great with Windows 7 64bit O.S Hope you find the problem alot of times it is something simple at-least in my case .

The firefox media plugins could be making slightly different calls and hitting some bug in the hardware video acceleration. It's impossible to say without actually looking at the BSOD, but the fact remains that FF can't be causing it directly.
