MHT is a very useful file format for saving HTML web pages and all embedded graphics into a single file (also known as web archive).
The format is supported on IE, Opera, Microsoft Word, OneNote, etc. and comes handy if you need to attach an entire web page as an email attachment.
Now your favorite browser Firefox 3 cannot export web pages to MHT format by default but there’s an excellent add-in called UnMHT that makes MHT support in Firefox better an IE and Opera.
With Un-MHT, you can read any MHT files in Firefox just like any other HTML or text page.
Other than viewing MHT files, this add-in adds a "Save all tabs as MHT" feature that lets you save the current window or all open websites as separate MHT files in one go taking the file name from title of the web pages.

Considering that Windows Desktop Search can index content stored in .mht files, this may prove very useful if you need to save your work and close the browser.

This is really good when you try to present a site offline.
Have been using ‘Mozilla Archive Format’ Addon since the start of Firefox . Have to tweak it to use for higher version of FF.
great tips Amit……thanks for sharing this..
I was missing this functionality in Firefox
You need a account to access it :( the add-on is still in development phase! But worth installing it! Thanks Amit.
Excellent plugin! The only time I ever had to open Internet Explorer was to view OneNote MHTML files. Now that I have support in FF thanks to this extension, I will never have to open IE ever again. Thanks!

Sounds better than other ways of saving and archiving webpages !
Ok Amit, I need a solution for this problem. I am in a browser downloading .jpg files by doing Save As. Now I have three folders to download the files from, lets say a web page, and the numbering in each of the folder is same. For example, Folder A contains files from 1 to 10 - 1.jpg, 2.jpg, 3.jpg and so on. Folder B also contains files with same numbering. I was to save all the files from the three folders in a single folder on my local drive. The problem is that IE or any other browser keeps asking me if I want to overwrite an existing file with a similar sounding file name from another folder. Do you have trick up your sleeve? :)
YOu may trying downloading the full web page (with images) to your desktop using the “Save as” command and then these files should get saved in a new folder on your desktop.
