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.

Last updated 2 years ago. The main reason I would use this extension is for order pages that I may have closed, then opened later eg AliExpress price changes. So after a session Aliexpress needs logging in again and the tab is no longer original, hence it does not work. Sadly, uninstalled.

Doesn't work at all - I click the icon and nothing happens.

Firefox 62 64 bit Linux, private mode.

the older version is so much better, in the tab, you could see, that anything is working, and now the window on the checking side is not to hide :(
