Hi, there,
I completely agree with Karel Klapka: this add-on works, but of course there's room for improvement (as the author says).
Negative comments came mainly from the fact that the action button wasn't in the right place - it should be on the calendar page.
There may be a solution for that:
Add line: "allowed_spaces": ["calendar"] under: "browser_action" in manifest.json

Thanks a lot for your work on this great plugin!!!

Plugin works - you have to activate it via the Open Multimonth button, visible on Mail view title bar.

See further help and description at github home page:


The button is sadly not visible on Calendar view, as one would expect for a calendar plugin:-). Maybe that the previous reviewers just did not know how to activate it because of that.

1] First humble wish: please put the link to github page and usage instruction to the plugin description on thunderbird.net page

2] Second humble wish: please put the [Open Multimonth] button to the Calendar view:-)

It is great, best wishes for the plugin growth!!!

Thanks once more,
Karel Klapka

Don't waste your time: it doesn't work

What doesn't work exactly?? Could you report at https://github.com/gilgaTheDev/multimonth-view-addon/issues, please?

Now that another user has told us how to activate it, I change me review to 3*. The dev should of told us how to activate it, AND, for those of us using dark themes the icon on the mail view toolbar is hardly visible.

ALSO, the icon should be on the Calendar view toolbar, not the Mail view toolbar. It if was, then it is a lot more likely that we would have seen it.

I would like to give at least 4* but the above oversights preclude that. Once they are fixed I will change me review.

Simply does not work. It says added, but nothing changes and I have no instructions.
