"Checker Plus for Gmail" has gone from excellent to poor overnight! This extension has worked well for me in the past, but a few weeks ago the wheels came off:

I can no longer reply to emails from "Checker Plus", and I get this mysterious "Unknown Failure" when trying to add my accounts. I suspect Google is the cause, but unfortunately, it may have doomed "Checker Plus" to the ranks of "NOT READY FOR PRIME TIME".

it works fine but i almost threw up when i saw the ui change please for the love of god stop making everything circular first youtube now this. let me change it back at least it's so ugly

Good addon but leaving the placeholders for premium only features in menus is a dick move. Promptly removed.

It's a great extension, i use it for years. Recently however it started to throw a detection error which is quite annoying hence the 2 stars

Have been starting to get a "detection mode" error to where it constantly asks me to autodetect my accounts, and it has gotten on my nerves to the point of uninstalling.

I love it but since the last update I can't use it anymore it sais: we have a special offer for bla bla bla and it doesn't show new emails

sokszor lefagy hibát ír!

I really hate the material design.

Can not login on Firefox 57. Please make it work.

First i'd like to say its a great extension. And i know it is not targeted for FF57+ however it does install on FF57b2 however it doesnt work. First it doesnt check for new mails (it says "cant access dead object") and then in th eoptions i cant control watched labels since when i try to unselect inbox it says "observer is null" :)

P.S. on FF55 situation is the same. :(

Somewhy it blocks push notifications on android device.
