Rated 4 out of 5 stars

Returns much needed functionality to Firefox. Really useful for plugin installations where you just need to quickly run the install file, instead of downloading to a folder and launching it manually.

This extension has a minor annoyance for me though. When opening up non-executable files, it adds a "Open in default Win32 application" along with the usual "Save File" and "Open With' entries in the download dialog. This makes the entire dialog look clunky and claustrophobic. It would be better if that option was added as an entry in the drop-down box right next to "Open With". This way the UI is much nicer and there is no duplication of functionality (Open With vs Open With Default Win32 app).

This review is for a previous version of the add-on (2.0.1).
