Just Works Rated 5 out of 5 stars

Works great for both Firefox and Thunderbird. Thank you for fixing a real annoying problem! After enabling FIPS in Firefox and having a few https app tabs as startup page I could get up to ten (sic!) password prompts on a typical Firefox start, before installing StartupMaster.

This review is for a previous version of the add-on (1.3.1-signed.1-signed).
