Memory goes off the charts, firefox needs to be killed.

Reproducible: Always

Steps to Reproduce:
1. Open the mht file with firefox
2. watch your single-core machine get on its knees
3. kill firefox

Actual Results:  
memory usage shoots up, got to over 1GB the first time before I could kill it.

Expected Results:  
fail gracefully if it's a bad file, which I'm note certain it is (works in IE, etc)

Does it work if you run Firefox in the safemode ?
(close ff and click on the Firefox safemode entry in the windows startmenu)

my bad - I guess mozilla/firefox doean't handle the MHT filetype internally?

in safe mode when I load the mht, it asks how I Wasnt to open it (mhtfile is the
only entry).  I choose it, it pops open an Internet Explorer and show it to me
there.

when I open it in regular mode, firefox opens it directly (shows opening in
tabs... dialog) and the memory oscillates between 80M and 800M and eventually it
finishes loading while still using 770M of RAM.

Based on this, I guess an extension or plugin might be handling it?

it's an extension if ot works in the safemode.
(safemode is just Firefox without extensions)

Mozilla doesn't support mhtml Files, see bug 18764

marking invalid (you can't report extension bugs in bugzilla)

thank you, sorry for the trouble.  i will try to contact the author of the
extension, Christopher Ottley, even though there appears to be no conatct info
for him.
