> What version of flash are you using?

The latest version, the actual number is too long for me to remember, but I updated my Ubuntu to the latest.
Confirmed on Fedora 10 with FF 3.1b3 and flash plugin 

Build identifier: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9.1b3) Gecko/20090305 Firefox/3.1b3

Crash report:
This bug is not limited to btw, I get the same result with all flash based video content (youtube etc. etc.)
This is in safe mode or a new profile?
Summary: Fullscreen video crashed firefox → Fullscreen video crashed firefox [@ ]
Version: unspecified → 1.9.1 Branch
This was in safe mode. I've also just reproduced the crash with a random youtube video and safe mode + a new untouched profile:

The crash does not occur if hardware acceleration is disabled in the flash plugin.

Backtrace points to which in my case is provided by NVidia (version 180.29). I would have attributed this to a NVidia and/or Adobe flash bug, but everything works perfectly in Konqueror (exact same flash plugin used) both with and without hardware acceleration enabled.

======= Backtrace: =========
well, i'm glad you'd attribute it to nvidia, because that's all we can do. file a bug w/ them and provide urls to cross link these bugs.

just because one browser doesn't crash doesn't mean it's the fault of the browser. the stack clearly faults nvidia, as they don't provide symbols we're unable to do anything. it's nvidia's job to either provide symbols or work w/ the caller to debug the problem. most likely the caller is adobe and they can either work w/ them directly, or through our bug system. however we can't do anything. and they can't until you report this bug to them.
I've tried poking nVidia about this at

There is a workaround which is to create a script that does the following.
export LD_PRELOAD=/usr/lib/
