SInce the recent move to Webextensions sometimes it's not possible to perform any action on emails from this extension. All actions are affected - mark as read, archive, delete. Right click on the extension's button and 'Refresh' doesn't help at all. Only restart of the browser somehow resolves the situation, but not for long. It used to be the best Gmail extension around, but I'm starting to reconsider moving to something else :-(

The bottom buttons don`t work

This was a great extension but not that it's moved to new add-ons API the buttons no longer work despite two updates.

This used to be amazing, but the WebExtensions version is unreliable and the buttons don't work. I switched to "Checker Plus for Gmail™"

Best Gmail notifier add-on in AMO.

Crap! It does not integrate with my googlemail account inbox whatsoever and is separate to my actual inbox googlemail account!!! really fucking useless!!

I just solved an issue with absent notifications in Firefox 57. I removed add-ons from sync preferences, then refreshed Firefox profile and reinstalled all add-ons. Now gmail notifier works without any problems as previously.

Getting an error message while opening the mail in full view..

5 stars for the old version, 1 star for the new WebExtensions version.

Couple days on the new version, waterfox kept crashing randomly. Old version 0.7.4 installed and all shiny + I got my tray icon back. (*) for refurbished, (*****) for legacy extension.
