Rated 5 out of 5 stars

GM-c is currently unable to check accounts in Firefox 53.0 or Pale Moon 27.3.0 presumably due to recent changes to Gmail by Google.

Until the awesome developers at Gmail Manager-community are able to adapt this add-on to the new Google changes, if anyone finds a substitute *working* gmail-checker, PLEASE share your findings here. We are all in this together.

Thanks! :)

This review is for a previous version of the add-on (0.7.1.2).  This user has other reviews of this add-on.
