I've used this add-on for many, many years. Great for checking stock on shopping deals, waiting for new forum posts, monitoring live market data, or alerting me to election-night data updates. I'm surprised how often I find it useful, tbh. And It's been consistently reliable for years and it's always worked well for me.

Perfect for my purpose. Awesome job!

Working totally fine and free for me in 2023.

Does what it says out of the box. Thanks to the developer!

In 2022, I used Check4Change to help me monitor newly-listed tickets and price drops on tickets at StubHub. With this extension's help, I was able to snag a music concert ticket to my favorite singer of 2021, Gracie Abrams.

Does what it does perfectly. I'm an author and use it to know when my sales figures update. Hearing the "Ch-ch-ch-changes" jingle is always a delight :)

Works great, but you must first select the text you want to check for changes and then click on the c4c icon.
