great Rated 4 out of 5 stars

Pros:its great tool. No need to mention.
cons: Account setting is displayed and editable to everyone. If multiple users use a computer and somebody changes the account setting, the generated password changes.if you don't have backup of your setting you can be lost.If the setting is displayed only after master password and is unique to every user depending on master password it would be more useful in multi users setting. In option of character "lower case + upper case + number" is missing. Some website does not allow special character but ask for the above combination. The Above character set is available in online version though.

This review is for a previous version of the add-on (1.6.1).
