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

I have never seen one password. This does not work, does nothing.

Doesn't Work

Does absolutely nothing. Not the only one of these that do nothing!

The worst thing is advertising, mentioning the applications you have on Google Play.

After another big mistake is to have to press and it stays the banner above everything annoying the access depending on which web to be able to see the password.

There is much to improve in my humble opinion, and most importantly remove spam.
