User Reviews

Users largely praise Word Counter for being simple, reliable, and fast, with useful statistics like estimated reading time and extra metrics, plus unobtrusive UI (especially right-click). It’s handy for quick checks (e.g., students’ word counts). However, several reviews flag accuracy issues (miscounts, especially with apostrophes), limited language support (Asian languages), and occasional non-functionality. Many also request more customization options for displayed sections and reading-time controls.
Pros
  • Simple and easy to use; just works as advertised.
  • Provides useful statistics, including estimated reading time and extra metrics like average word length and longest word.
  • Unobtrusive integration (right-click) that doesn't clutter the workflow.
  • Helpful for quick word checks (e.g., checking students' word counts).
Cons
  • Occasional accuracy issues: miscounts, especially with apostrophes or punctuation.
  • Not fully compatible with Asian languages.
  • Occasional non-functionality or bugs (fails to work in some cases).
  • Requests for more customization options (enable/disable sections, adjust reading-time features).

Excellent. Simple. Clear. Does what it says it will do and even a little more. I use this extension to give me a rough idea of how long it'll take to read something. I estimate (conservatively) 200 words a minute. Thank you for making this, and making it available. -- Joshua :-)

Is Word 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.

Word 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.

Word Counter is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
