Fixing Firefox IO in lab computers
Firefox is over protective to save you from crashes. That said it's vital to turn it off in the lab unless you enjoy waiting for 60 seconds for out Disk Server to respond (sorry about that).
Fixing it
- Press CTRL+L to select location bar
- Type "about:config" to the location bar, go there
- Ignore the warnign about voiding the warranty
- Write "crash"
- Double click on the entry labeled: browser.sessionstore.resume_from_crash
And your firefox will be snappy once again.
