It's fine

Works pretty well. Plays a sound and opens a tab when firefox auto-updates the addon though, which is really jarring. I don't expect a plugin to randomly start making noise when it's not in use.

Working totally fine and free for me in 2023.

Totally useless, should be remove from addons

No longer works, poor UI, paid interface.

Does not load page, severely limited options in the "FREE" version, save your time.

This extension worked way better in the past, i've came to use it again since a week with 10 tabs and i got a ton of false positive, and i just select one world like ( unavailable or a price tag ) always been a mac user, but it seems like something is wrong with these newer releases.

Says there are changes even when there aren't. Basically useless.

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.
