Flash crashing in Firefox

I sent this to Edubuntu Users list already, but haven't received any responses. Figured I would try this list. I apologize if some of you are on both lists and receive this twice....

I'm having an issue with Flash crashing in Firefox on each of my LTSP servers. Firefox and Flash are are up to date. Flash doesn't crash on all sites, just the majority of them. I have purged flashplugin-installer in favor of the adobe-flashplugin from the Canonical repos and am still experiencing the issue. If I launch firefox from terminal (on thin client) and then access the offending websites, I get the following errors.

###!!! ABORT: DRI2Connect: BadRequest (invalid request code or no such operation): file /build/buildd/firefox-24.0+build1/toolkit/xre/nsX11ErrorHandler.cpp, line 157

###!!! [Parent][RPCChannel] Error: Channel error: cannot send/recv

If I go to the server console and launch firefox from a terminal, I get

Failed to opem VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory

but the sites with Flash work from the console. I believe this has something to do with video drivers, but am not 100% sure. In the meantime, I have been pushing users to use Chrome with built in Pepper flash player. This is working, but Chrome seems to be slower than Firefox and I haven't been able to figure out if I can do global settings on Chrome like I can using syspref.js in Firefox. Ultimately, I just want to get Firefox and Flash working well again.

Any help or guidance would be greatly appreciated!
