MaxLength Revealer

If you paste a long, randomized password into a field, it will sometimes be cut off if the field has a maximum length, and it is difficult to see when it happens.

This extension will highlight password fields on the page and display their maximum length. It will also reveal the password entered. Both of these features are useful for people who copy and paste large, random passwords from managers such as LastPass. For example, my own passwords are always 128 characters in length, provided the website will allow it.

The password field will show up with a dotted border. The color will be orange if there is a hidden maximum length on the field, and green if the field has no maximum length. If it is green, you are safe to paste your super long password!

Note that this extension will rescan every couple seconds. It will also try to include password fields within frames, but this does not always work. If there is no dotted border, my extension has not scanned the field.
