Backspace removes two chars in web shell

[no_connection]

Not sure what the behavior should be but for me backspace removes two characters when in web shell.
This makes for some annoyance when correcting typos etc.

FreeNAS-9.2.1.5-RELEASE-x64 (80c1d35)

Happening with Firefox of three different versions. 19.0.2, 12.0 and 8.0.1
Seems fine with Opera but then up/down arrow won't work like it should.

Yeah, we've had this problem before.. we can't reproduce it easily. :(

Our guess is that it's a browser or addon problem. I've never had the problem on my own systems but I've seen it on a few customer's machines.

I tried adding all my addons to a fresh install of latest FF but could not reproduce the issue.
I will see what I can come up with.
