Rated 5 out of 5 stars

I used IE for many years just because I could save the pages that interested me in mht format. I just changed IE for Firefox when I finally found an addon that allowed me to open those pages that for so long I was saving (with IE). By today I have been using the addon for many years to save pages as .mht and I have literally several thousand pages stored in my HD, external disks, pen drives, CD's, etc.
It is not practical for me to convert all that material. If there is not a solution soon I will have to stop using Firefox.

This review is for a previous version of the add-on (5.1.2).
