masterpassword for firefox
Master Password implemented as a Firefox extension
This is a firefox addon implementing the masterpassword algorithm invented by Maarten Billemont. You can visit his website at masterpasswordapp.com.
Please note that this plugin is not affiliated with Mr Billemont
Regardings adoptions for Firefox on Android: Personally I have no interest for it, but again pull requests will be accepted as long as they don't deteriorate the experence on desktop versions.
Support for Firefox version before v51 was dropped with the 2.1 release of masterpassword for firefox.
Download from the Mozilla addon store:
