By "fails to load", i mean using it to open MHTs. Just to clarify.

Confirmed here save fails and opening too:

- "Save as MHT..."
- "Quick Save" 
- "Save multiple tabs as MHT"
- opening MHT file in the browser

on Windows XP SP3, 4GB RAM, Nightly 47.0a1 Build ID 20160218030349 on a fresh profile + UnMHT 8.1.0 and and throws the same error:


> Failed to retrieve file.
> [Exception... "It's illegal to pass a CPOW to native code arg 0 [inIDOMUtils.getUsedFontFaces]"  
> nsresult: "0x80570036 (NS_ERROR_XPC_CANT_PASS_CPOW_TO_NATIVE)"  location: "JS frame ::

> UnMHTSaveContext.prototype<._startGatherDocument/</</gatherFont :: line 3467"  data: no]: 
> https://www.bugzilla.org/

As for the opening a MHT file, it doesn't throw an error, it just doesn't open files in the browser, and the browser keeps asking what to do with this file instead opening it, when I choose to "Open with" and choose Firefox, it keep asking again instead of opening it and so on...

After disabling Options >> General >> Startup >> "Enable multi-process Nightly", the add-on is working back as by magic wand, just like in another UnMHT 8.1.0 bug 1248120 I reported. 

The add-on is completely broken with "Enable multi-process Nightly" feature enabled
and not only does not work but also break switching between tabs as in bug 1248120 and the add-on is working back after disabling the feature as well as switching between tabs bug also is gone then.
