Thunderbird 78 (September 2020)
Please note that I'm aware about Thunderbird 78 and the fact that Signature Switch
is no longer compatible with this new release.
Just like many other Add-Ons, Signature Switch
will have to be redesigned from the ground up to work with the new APIs.
I already started to do a complete rewrite of my Thunderbird-extensions:
However, they're still in early alpha-stage with just basic functionality.
Contributions (pull-requests, testing, etc.) are welcome.
The Web-/MailExtension APIs
also don't yet offer all of the necessary methods/hooks to implement every existing feature of the old XPCOM-/XUL-addons.
This will hopefully improve in the near future. So please be patient.
Oh… and by the way: Leaving (negative) one-star reviews at addons.thunderbird.net won't motivate me to speed things up!
I'll publish installable XPI-files here, once they've reached beta-stage.
All of this is a pretty time-consuming effort; which is mainly done in my spare-time.
