I have used FF and Mozilla Archive format add-on since years. Thousand's of MHT saved as single file. And now no longer supported.
I just created an account here for the sole purpose to announce that I leave this browser.!!!!
I'm now on the latest Opera and i'm very pleased with my move. I have got back my .mht single file and the browser is incredibly fast. I will now close my account.
