For those not familiar, here is a quick screenshot that shows how it works:
No suitable alternatives (yet)
- Errator — ghost town, only a few users and no reviews
- JS Error Notification — kinda weird, few users and only one review
Replace with unpacked extension
- Download the extension (ZIP file) via GitHub
- Unzip the file to get the extension folder,
- Move the folder to a permanent location (e.g.,
- Open Chrome browser, in the address bar visit
- Click to toggle “Developer mode” (upper-right corner)
- Click “Load unpacked” from the top menu buttons
- Choose the extension folder,
- Click “Select” and done.
After selecting the folder, it immediately will appear among your other extensions:
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.
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.
Seems that many of these “big projects” are doing away with a lot of useful features that many developers make heavy use of! Such a shame that they make all these radical decisions, without actually seeing how much of their user-base may use these features.
My biggest complaint about FireFox – was just THIS sort of behavior. They removed so many useful features that I used quite frequently like: Viewing the contents of cookies, being able to import my crafted search-engine plugin XML files (for testing before submission), backing up search-engine plugins (a BIG ouch when removed), and several other features!
I don’t expect GOOGLE, MOZILLA, and other “big projects” to cease this one-sided decision-making anytime soon, either.
This is exactly one of the major reasons why there are many alternative projects cropping up everywhere, to include an alternate to WordPress. I LOT of people are very upset that WordPress is forcing “Gutenberg editor” upon everyone – and increasing the serious “codebase bloat” in the process.
It’s only going to get worse, I’m afraid – as the “big-company mentality” sets in for the long haul. We, the users, are just “numbers” and nothing more.
Always happy to see workable alternatives presented, though.

I was doing research on a JS notifier chrome extensions and stumbled on this post.
I ended up using the mentioned extension.
Keep up the good work Jeff.
I just resubmitted this to the chrome store. Hopefully it goes through.
Awesome. Let me know if they accept it, and I will update the article.
Waiting for the submission answer ;-)
Also, I noticed while working on this project at some point, I was no longer able to manually install the legacy Manifest V2 version of the extension. It seems chromium could now be blocking legacy extensions as well.
It seems the Chrome Store has some longer delays for extension updates. I made an initial publish attempt with something that simply runs, just to see what issues there would be to publish. After it went live, I published a more fully working version and am still waiting for it to launch. I’ll update here when a much better working version is live.
Another update, 4.04 beta is live on github and pushed to the chrome store (currently, taking about 3 days to go live). The latest allows you to specify domains to apply filtering. Uncheck “show icon on all sites” and then specify the domains you want to be active.
