Warn Common Password
Extension Delisted
This extension is no longer available in the official store. Delisted on 2025-09-16.
Displays warning notification if word entered in any password field is present in 500000 common passwords. Works entirely offline.
This addon compares a password that you enter in any website against a list of 500000(!) common passwords from a publicly available list.
If matched with a password from the bundled list, it shows a warning notification.
THIS EXTENSION WORKS ENTIRELY OFFLINE and does NOT make any network call/request to any server. It comes bundled with a top 1 million common passwords list.
The "common Passwords list" is obtained from the Github Repo : https://github.com/berzerk0/Probable-Wordlists and it was NOT generated/collected by the developer of this extension. This addon simply "reuses" a publicly available list in the repository above.
Review the code of this extension in my github repository here : https://github.com//gkrishnaks/warn-common-password and this extension is licensed under GPLv3.
