New Firefox Extension Available!
We have completed the full rewrite of our Firefox extension, and submitted it to Mozilla on 20-Jan-2018. But we have no control as to when it will be reviewed and added to the official addon page. (It's been 48 hours so far, and nothing but radio silence.)
In the meantime, if you would like to start using the app now, we have set up a provisional version that you can access at this extensions page. Please keep in mind that this is a full rewrite of the Firefox extension, so consider it a beta version. And please report any errors to admin-at-gmailnotes-dot-com.
In case you are wondering, we still need to rewrite the web site and instructions, and we will try to get that back online in a few weeks.
For Firefox Users
Gmail Notes is a web application for attaching private notes to your Gmail. With Gmail Notes, you can create a note for each conversation in your Gmail account. To use Gmail Notes, you start by installing a Firefox extension which places the application in the Firefox sidebar. You can see Gmail Notes in this screenshot. And you can get more info at our Getting Started page.
You can then connect to the Gmail Notes service using your standard Google account name and password. When viewing a Gmail conversation, you can view/edit an existing note in the sidebar, or you can create a new one. One note can be saved for each conversation in your Gmail account. The app provides a rich text editor so that you can highlight text, create lists, include links, etc. For more user interface details, including some screenshots, look at our Everyday Use page.
Gmail Notes is not an integrated feature of Gmail, but a separate web application running on the Google Application Engine Framework. So your notes are stored separately from your Gmail data, although they are still in the Google infrastructure. And as a separate system, there are certain things that Gmail Notes cannot do. It cannot, for example, highlight which messages in your inbox have notes attached to them; you can easily do that using labels or Gmail superstars, but you will have to do it manually. There are other limitations listed on our What It Doesn't Do page.
Gmail Notes is a free service open to any Gmail user.
