Rated 5 out of 5 stars

This add-on is absolutely worth 5 stars. It gives me a very easy way of saving many tabs in one file and then being able to open them directly as they would display had I opened them live. HOWEVER, please note that unfortunately version 2.0.2 is not yet compatible with FF 9.0.x (it worked perfectly in FF 8). It is not possible to open a MAF file containing multiple tabs yet. If you are looking for that option: wait for a newer version than 2.0.2. This issue has already been reported recently, so I am pretty sure that it will be fixed soon.

This review is for a previous version of the add-on (2.0.2.1-signed). 

This has been fixed in version 2.0.4, thank you for the report. This version is already available for manual installation and will probably be available as an automatic update in the next few days.
