But owing to the highly customizable nature of Firefox, you can add MHT functionality to Firefox in no time. What you need to do is download an add-on called unMHT (https://addons.mozilla.org/en-US/firefox/addon/8051) and install it in Firefox. This add-on will add the Save as MHT and Save all tabs as MHT in the File menu of Firefox. Now you can save any page or all pages open in tabs of Firefox to a web archive MHT file.
The problem with unMHT Firefox add-on is that, by default, it allows you to save files only. If you double-click on any of the saved MHT files, it opens in Internet Explorer. Its no fun to use Firefox to save the MHT files and then to have to open them using Internet Explorer. You can associate MHT files with Firefox so when you double-click on MHT files, they open in Firefox instead of Internet Explorer. To associate MHT files with Firefox follow these steps :
- Make Firefox your default browser (Its pointless to associate only MHT files to Firefox). To make Firefox your default browser, Open Tools → Options → Advanced in Firefox and click on Check Now. When asked choose Yes.
- Right-click on an MHT file and select Properties. (If you do not have an MHT file, you can create using either Internet Explorer or Firefox web browser. In Firefox, just open a webpage and choose File → Save as MHT.)
- In the Properties window, click on the Change button.
- In Windows Vista/7, click on the Browse button and browse to firefox.exe. In Windows XP, you can browse the firefox.exe directly. The firefox.exe file is typically located in C:Program FilesMozilla Firefox folder. Select the Firefox.exe and click OK.
- Click on the OK button on all the open windows to save the changes.
- Enjoy viewing MHT files in Mozilla Firefox.
