Rated 4 out of 5 stars

On Firefox 5.0.1 running on Mac OS X 10.6.8, I found that the Mozilla Archive Format 1.0.0 add-on caused Firefox to regularly consume 100% CPU for several minutes, during which time it would be unresponsive. UPDATE: I was mistaken. Although the problem initially disappeared after I disabled the Mozilla Archive Format 1.0.0 add-on, the problem has now returned, and the Mozilla Archive Format 1.0.0 add-on is still disabled. I've increased the rating I'm giving to the add-on accordingly.



The add-on doesn't provide an option to save web pages in a format that allows them to be previewed using "Quick Look" in the Finder.



Other than that, it seems to be OK.

This review is for a previous version of the add-on (1.0.0.1-signed). 

While I don't have access to the Mac platform, the issue with Quick Look seems a limitation of the operating system. Maybe there is a way to make Quick Look compatible with MAFF or at least MHTML. You may try and write to a Mac-specific support forum, or to the Mozilla Archive Format mailing list or newsgroup (http://maf.mozdev.org/feedback.html) to see if other users have resolved the problem.
