Character Counter Firefox

Character Counter

Allows you to count the characters, words, sentences, keyword density and more by adding a right-click option after you've made a text selection on any website.

Features & Capabilities

This is a very simple and lightweight addon that will allow you to analyze a text as it adds an option to your menu when you highlight text and right-click.

You will then be redirected to the character counter which will safely analyze your text and display the results to you.

For your privacy - the text is sent over client-side (e.g https://www.charactercountonline.com/#text:HelloWorld).

I hope this addon will help you out and all your feedback and comments are much appreciated and will be used to improve the addon.

It works but opens up a separate window which is inconvenient. Uninstalled.

Is Character Counter Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Character Counter does not require any sensitive permissions.

Risk impact analysis details
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Character Counter may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
