Firefox 17.0.11 ESR : add-on version 3.0.1-3.0.2 NOT working, but v3.0.0 OK Rated 4 out of 5 stars

Seems a very good add-on.

However with 'Firefox 17.0.11 ESR' and 'Mozilla Archive Format' version 3.0.2-3.0.1, when doing a 'save as' or a 'save page in archive as' the possibility to save as MAFF or MHTML does not appear in the drop-down box (only the regular save options).
(in the change log, I can see that something has been changed in a the 'save as' dialog box in version 3.0.1-3.0.2)

No problem with add-on version 3.0.0
(I have to remember not to update this add-on for the moment)

This review is for a previous version of the add-on (3.0.2).
