I've revoked my original 4-star review - here's why:

It seems the recently updated extension no longer supports the Firefox ESR channel for older PCs that can't run Windows 10/11.

The extension was working fine until 7th April 2026, then on that day a new version installed automatically, and now it's just a mass of error messages ... all of them in a bold white font on a bright red background.

The messages rapidly accumulate down the screen, over the top of emails, rendering the extension near-useless.

Decided to 'update' it to disable any interaction with emails when it's incessantly requesting relogin... well, if you're so desperate for 1/5 stars, here it is...

Janky plugin that doesn't allow you to change the order of your email accounts unless you add them in manually - and then you are limited to 3 accounts before you have to give him money. Bait and switch. Uninstalling.

Very impressive extension, really just does the whole setup automatically. Thank you, Jason.

Excelente extensión, ayuda a estar pendiente en cualquier pantalla del correo

This addon is not even open source. Author can see all your email and contents in it. Look at his homepage and privacy policy. At least he is being honest about it.
It is upto you, users to trust this random man on the Internet with your gmail contents. I don't know why Mozilla has this under "Recommended" section.

First too get notified for all that website its okay with us

How do people trust their data to a random guy's extension instead of googles relatively solid service never ceases to amaze me.
