Make a wallabagger version for Thunderbird

Hi,

I use Thunderbird as an RSS reader and for now to push an article from Thunderbird to Wallagag, I need to:
* open it in Firefox
* use Wallabagger to add it to Wallabag

This procedure is quite heavy...

So would it be possible to make a Thunderbird version of Wallabagger?

As Thunderbird handles webexts too, I suppose that the specific work could be light and would mainly consist in adding a button at the good place... But maybe I'm too optimistic...
