Firefox: https://addons.mozilla.org/firefox/addon/originmarker/
A browser extension to allow users to easily identify phishing domains all done client side.
With a marker in the bookmarks bar that changes based off the active origin/domain the user is viewing.
It can be renamed per origin manually or automatic using the hash of the origin encoded in emoji.
Do not enable bookmark sync between devices.
Rename the folder/marker on the origin or just use Automatic mode.
When you rename a marker it will not change the mode.
If no Marker name is set emojis will be used to identify the origin.
This works by using a sha256 hash of the origin encoded into emoji.
Like Universal mode but with a personal salt. It will be different emojis per origin then other users.
Markers will not get a automatic value.
The Origin is based of the protocol, hostname and port number of a URL
