As the title implies, I am unable to open any local files on Firefox. The tab just keeps loading forever and using up all available memory until it crashes the tab. (the browser still remains operational, since the crashing process is a child process of the main browser) I took a look at the process in GDB and it looks like it's hanging in `read () at /usr/lib/libpthread.so.0`, called from libxul.so. (possibly a spinlock, since it also grinds one of my cpu cores down) I've checked and this problem is not related to my profile, settings, or extensions. I'm at a complete loss for what to do now to fix this, since I don't have the time or disk space to build a full debug build of Firefox and figure out what's going on.
