TB 78.4.0 : ThunderKeepPlus installed from file (didn't find an update). Before, I had the icon in the top bar - but in TB 78 it disappeared after each restart. I discovered, that I have to move the icon to the bar below: e.g. between the global search box and the three thick bars on the right - here, it is kept over the restart.

10.11.20: doesn't work anymore. Message says "Sie wurden abgemeldet. Aktualisieren Sie die Seite, um sich wieder anzumelden und weiterzuarbeiten." Translated: I was logged off and shall reload the page to login and continue.

When I click "Reload", the same message again. If I close the popup with the message, it stays but doesn't communicate with Google.

I cleared TB cache and cookies, no change.

Update: after I installed addon "G Suite in Tab", I got the same error for Google Keep. Then, I opened the Google calendar (from G Suite), got the Google login screen. I did a logoff/logon, now Google Keep works from both work: "G Suite" and "Thunderkeepplus".

Although stated "compatible Thunderbird 13-45.*", version 0.9.1 runs in Thunderbird 52.0.1 32bit.

The addon just adds a button "Google Keep" to the menu bar of Thunderbird. If you push it, a new tab in the Thunderbird main environment is opened, that shows a browser window to Google Keep. You have to login in this browser window at the first call, then your credentials are saved. No settings in the addon itself, really simple.

And that's why I use this addon:

Websurfing with Firefox, I open links as tabs, so my tab bar is really filled.
Not so in Thunderbird, where I read my mails mostly in the preview window - so I have no or just few tabs in Thunderbird.

As I use lightning (connected to my Google Calendar), my Thunderbird becomes a "single point information center".

To enhance Thunderbird further to a single app mail/calendar/notice point, I installed this addon.

What I miss: some kind of addon to connect notices between XNote/Xnote++ and Google Keep

This review is for a previous version of the add-on (0.9.1).
