Rated 4 out of 5 stars

In the recent version 8.3.0 in FF 51.0.1 pages are "saved successfully" (according to UnMHT's report), but they are not presetn in "Downloads" folder of file system.
Interestingly, there is shortcut file in "Recent" folder, pointing to absent saved .mht file in "Downloads" folder!
It is not about antivirus software on my PC, because saving to MHT works fine from Internet Explorer to the same location ("Downloads" folder).

This review is for a previous version of the add-on (8.3.0).
