Actually Firefox 3 still does not support the.mht format but there is an addon called Unmht that can help to save the webpages in the.mht ( webarchive) Format. I was using the Mozilla Archive Format is the Firefox 2 but when Firefox 3 was relesed I decided to stay in Firefox 2 since I did not have a supported webarchive addon. Once this plug-in is installed, click on the link to the dashboard and select “Open”. It may ask you to open it with Firefox if you have the unMHT add-on as described above. It may ask you to save the file to your local drive. Save it to your Desktop (or another location you will remember) and then double click the file to open it. UnMHT stopped working. This was a very helpful add on. WHAT'S THE DEAL? Firefox is version 39. Do I need to roll back to an older version?:-( Very unhappy.

I already introduced UnMHT in a previous post about Translated Excel Functions, but I think this Firefox add-on deserves its own post since it’s so useful.
What is UnMHT
UnMHT is a Firefox add-on that generates MHT files from web pages. MHT or MHTML is a file format like many others, except it works like an archive (.7z, .zip, .rar, etc.) and includes WITHIN the file all the necessary files, scripts, pictures and code required to view a web page offline, exactly like its original online version.
This is very useful. Everyone can have a different reasons to view a webpage offline, but they all share a common thing: no need to be connected to the Internet to view the page.
Installing UnMHT
Of course, since you’re already using Firefox, this will be very, very easy. Simply open your extension manager (Ctrl+Shift+A), enter “UnMHT” in the search field, search and install. That’s it! Nothing to download, no link to go to and no restart required!
Creating MHT pages
Once UnMHT is installed, simply go the a page you want to save for future use, then go in File -> Save as MHT and Voilà! You’re done. You can also simply right-click anywhere on the page and choose “Save as MHT…“. Also note that you can even save multiple opened tabs as MHT.
Enjoy!
