Heads up about the JavaScript Errors Notifier extension for Google Chrome. Looks like it was removed from the Chrome store sometime last year. Not sure of the reason behind it, but can tell you that currently there are no suitable extensions to replace it. Kinda sucks because JavaScript Errors Notifier was one of my favorite “always on” extensions. It makes it easy to spot any JavaScript errors as you develop, design, or browse the Web. Fortunately there’s still a way to use this extremely useful extension..
For those not familiar, here is a quick screenshot that shows how it works:

If the current web page does not have any JavaScript errors, it is greyed out. If the page does have any errors, the little icon displays red. Then if you click on the icon, it pops up a little dialogue with specific details about each error. Again, super useful for web developers and anyone who wants to keep an eye on things.
No suitable alternatives (yet)
I’m hoping that this post will bring attention and “inspire” someone to pick up development or fork the JavaScript Errors Notifier addon. Currently there are no suitable alternatives for Chrome. So it falls into the “one of a kind” and “virtually priceless” categories.
To be fair, there are a couple of other “JavaScript notifier” type plugins available for Chrome, but they don’t really inspire a lot of confidence:
- Errator — ghost town, only a few users and no reviews
- JS Error Notification — kinda weird, few users and only one review
You can check those out if you’re feeling brave, but for me there’s too many red flags to take seriously. The original, now-removed JavaScript Errors Notifier extension had many, many users, and many great reviews.
So what to do? As a web developer, I can use the browser’s code inspector to really dig in and examine JavaScript (and other) errors on any web page. BUT as a regular human just browsing the Web, there is no way to monitor JS errors “as you surf”. I manage many web pages, and surfing around pages is one way that I keep an eye on things, catch errors, and so forth. Thanks to the JavaScript Errors Notifier extension, I’ve caught a lot of errors that otherwise would have been missed.
The good news? JavaScript Errors Notifier is still available on GitHub :)
Replace with unpacked extension
JavaScript Errors Notifier is developed by Sergey Barbushin. It’s currently available as a free Firefox add-on. For Chrome, the extension was available for several years at the Chrome Web Store via the following URL:
https://chrome.google.com/webstore/detail/javascript-errors-notifie/jafmfknfnkoekkdocjiaipcnmkklaajdThat’s now a 404 Not Found, sadly. The good news is that the source code for the extension remains available at GitHub. So for now at least, it’s still possible to run JavaScript Errors Notifier as an “unpacked” extension. This may change in the future, but for now it works great. Here’s how to set it up in a couple of minutes:
- Download the extension (ZIP file) via GitHub
- Unzip the file to get the extension folder,
/javascript-errors-notifier/ - Move the folder to a permanent location (e.g.,
/Applications/on macOS) - Open Chrome browser, in the address bar visit
chrome://extensions/ - Click to toggle “Developer mode” (upper-right corner)
- Click “Load unpacked” from the top menu buttons
- Choose the extension folder,
/javascript-errors-notifier/ - Click “Select” and done.
After selecting the folder, it immediately will appear among your other extensions:
JavaScript Errors Notifier running locally (click to view full-size image)I’ve been running the extension this way for a couple of weeks and it’s working beautifully. A few notes to keep in mind:
- The extension will break if you move the folder after install
- After installing, you can check for errors by clicking the “Errors” button
- At this time, there is only one error: “Manifest version 2 is deprecated, and support will be removed in 2023.” Not a huge deal really.
Hopefully, the extension author will jump back in and continue development. If not, then eventually it will no longer work, have bugs, etc. But for right now, running the extension locally/unpacked works great. Maybe it will buy enough time for some alternate JavaScript-notifier extensions to hit the scene.
A lot of people use this extension, so hopefully someone will pick it up, fork, or whatever is needed to keep it alive and awesome.
