👁️ obsolete, the feature is already builtin without requirement for this addon:

Every single one of these "show password" add-ons is fake. None of them work at all! I tested them all on Charles Schwab Online banking login and not one will show password. No buttons appear. Nothing happens when I click the text. Why do people build fake programs? This is something people need!

Don't work

It doesn't function on ANY site at all.

It doesn't fucking work
